EXPLAINED · WE RUN ONE OURSELVES

MCP, explained properly — and the 74 tools we partner with that ship one

Every SaaS company suddenly has an "MCP server". Most articles about it are either a press release or a wall of JSON. This one is neither. Here is what the Model Context Protocol actually does, drawn out rather than described; what it looks like from the inside, using real output from the server we run ourselves; and which of the 425 tools in our database offer one — with what it costs, taken from their own documentation, and "not stated" where they don't say.

Short answer: MCP is a standard plug. Before it, every AI app needed a bespoke integration with every tool; now each side implements one protocol and they all fit. It is free and open. Vendors' servers are usually included with the plan you already pay for — but 42 of the 74 partner servers we checked don't say a word about plan or price in their own docs, and a handful sit behind a specific higher tier. Details, with sources, below.

The problem MCP solves

Start with the annoyance, not the acronym. You are in Claude or ChatGPT, and you ask something that needs your own data: what did we spend on software last quarter, which support tickets mention the new pricing, is this contractor's paperwork done. The model can reason perfectly well about all three. It just cannot see any of it.

The old fix was an integration per pairing. Every AI app had to build a connector for every tool, and every tool had to build one for every AI app. Three clients and three tools means nine integrations to write and — the part that actually kills projects — nine to maintain when an API changes. That is the mess on the top half of the picture below.

MCP, an open standard originally published by Anthropic, replaces that with one shared interface. The tool ships a server. The AI app is a client. Each side implements the protocol once. Three plus three, and the fourth AI client you adopt next year costs nothing to support.

Our illustration. The count is the point: integrations grow multiplicatively without a standard, and additively with one.

That is genuinely all the idea is. The reason it spread so fast is not technical elegance — it is that it let vendors stop guessing which AI assistant their customers would standardise on.

Client, server, host — which is which?

The host is the app you look at (Claude Desktop, Cursor, VS Code). Inside it runs an MCP client that speaks the protocol. The server is the small program the tool vendor ships, sitting in front of their API or data. Confusingly, an MCP “server” often runs on your own laptop.

What is a “tool” in MCP?

A named function the server offers, with a JSON schema for its arguments — for example get_dossier(name). The model reads the list of tools and their descriptions, decides which to call, and the client executes it. The description text matters enormously: it is the entire instruction manual the model gets.

stdio or HTTP — what is a transport?

How the bytes travel. stdio means the server runs as a process on your machine and talks over standard input/output — private, no network, but you have to install something. Streamable HTTP means the vendor hosts it and you paste a URL, usually with OAuth. Most 2026 vendor servers are remote HTTP; ours is stdio, on purpose.

How it actually works

An MCP session is short and boring, which is a compliment. Messages are JSON-RPC 2.0. The client says hello, asks what the server can do, and then calls things. There is no magic and no model involved on the server side at all — the server is a dumb, well-described API surface, and all the intelligence stays in the client.

Our illustration, using the real method names. If you have ever wondered what your AI client is doing in the two seconds after you connect a tool: this.

Two consequences follow from that shape, and they explain most of what you will experience in practice. First, tool descriptions are the product. The model picks tools by reading their text, so a server with vague descriptions gets ignored or misused, no matter how good its API is. Second, the result goes into the context window. A server that dumps 40KB of JSON per call will crowd out the conversation and cost you money. Good servers return compact prose. That is a design decision, and vendors vary wildly on it.

Inside the server we run

We are not a neutral bystander here. We publish an MCP server ourselves — the Honest Atlas MCP — and everything above comes from having built and maintained one rather than from reading the spec. Here is what it is, honestly.

The problem we built it for is narrow and real: AI assistants are confidently wrong about SaaS pricing. Ask any of them what a tool costs and you get a number that was true eighteen months ago, or a vendor's headline price with the per-seat multiplication quietly omitted. Meanwhile we sit on 300 hand-researched dossiers with the real pricing notes, the honest knock, and who should skip each tool. Publishing that as a webpage helps humans. Publishing it as an MCP server helps the place where people are increasingly making the decision.

Our illustration of our own server. 242 lines of Python, standard library only, no account, no telemetry.

It exposes four tools. This is the literal tools/list response, captured by piping JSON-RPC into the server on the machine this page was built on:

$ echo '{"jsonrpc":"2.0","id":2,"method":"tools/list"}' | python3 atlas_mcp.py

search_tools     find tools by need, with honest one-liners + pricing
get_dossier      the full honest dossier for one tool
compare_tools    2-4 tools side by side
list_categories  orient a search

And this is a real answer, not a mock-up — get_dossier("Miro"), trimmed for length:

# Miro — honest dossier
Category: Operations & Workflow · miro.com

The honest knock: Per-member pricing charges for every member added to the
workspace, so an org-wide rollout multiplies at full headcount — and the free
plan's 3-board cap is workspace-wide, not per person, so real teams outgrow it
in days. Model who truly needs to edit before you buy seats.

Source: The Honest Software Atlas by AIBuilder Marketplace. Hand-researched;
no invented numbers. try_url links are affiliate links (commission possible,
never changes the take).

What building it taught us

The disclosure has to travel with the data. Our dossiers contain affiliate links. On a webpage the disclosure sits at the bottom of the page and the reader sees it. Through MCP there is no page — the model receives text and paraphrases it to the user. So the affiliate disclosure and the source attribution are appended to every single tool response, and the server's initialize instructions tell the model to pass both through. If you publish an MCP server with commercial links in it and you do not do this, your disclosure effectively disappears.

Compact beats complete. Our first version returned the full dossier JSON. It was accurate and useless: it ate the context window and the model started summarising away exactly the caveats we care about. Returning short, opinionated prose with the knock intact works far better.

Stale data beats no data. The server caches the dossier feed for 24 hours. If the fetch fails and the cache is expired, it uses the expired cache anyway rather than erroring. An assistant that says nothing is worse than one that says something slightly old with a date attached.

Zero dependencies was the right call. No pip install, no lockfile, no supply chain. One file you can read in ten minutes before you run it — which, given that you are about to let it talk to your AI assistant, is the minimum any of us should demand.

The 74 partners that ship an MCP server

We went through all 425 tools in our database and checked, one by one, whether the vendor themselves publishes an MCP server. The rule was strict: it counts only if it is documented on their own domain, or shipped from their own verified organisation. Community servers on GitHub — and there are hundreds, some excellent — do not count here, because you cannot hold a weekend project to an uptime promise. Several well-known tools failed that test: there are popular third-party MCP servers for Pipedrive, Aircall, Toggl Track and Kinsta, but nothing first-party we could find, so they are not in this list. Two entries here — Bybit and QuickBooks — are documented from the vendor's own GitHub organisation rather than their own site. We say so on their cards, and the update note at the end of this article explains where we bent the rule and why.

One disclosure that belongs here, not in the small print. Claude appears throughout this article as the example client, because it is what we use. Anthropic also created MCP — and Claude is a partner of ours, with an affiliate link we earn from elsewhere on this site. We have deliberately left that link out of this article. An article about a protocol, carrying a commission link to the company that invented it, would read like an advertisement whatever the intent. Cursor, ChatGPT and the other clients named here are not partners of ours at all.

74 passed. Each card below states what the server actually does, and what the vendor says about plan and price — in their words, with a link to the page we took it from. Where they say nothing, we say "not stated".

Amplitude Live

Hosted server at mcp.amplitude.com/mcp (mcp.eu.amplitude.com for the EU), OAuth, streaming HTTP. Queries charts, dashboards and notebooks, manages experiments, feature flags and cohorts, reads session replays, and reads and writes the tracking-plan taxonomy including branch workflows.

Plan & price: Their docs: "Any existing Amplitude customer can use Amplitude MCP from an MCP-capable client." No tier is named and no extra cost is mentioned. Write calls are gated by permission rather than by plan — creating or updating requires the Use MCP (write) RBAC action.

Their docs →Our dossier Visit Amplitude

Apollo Live

Server at mcp.apollo.io/mcp: search and enrich prospects, manage records, run sequences and read analytics.

Plan & price: Their docs: there is no additional cost to connect — your existing Apollo plan, permissions and credits still apply. Enrichment therefore still burns credits.

Databox Under active development

Server at mcp.databox.com/mcp with two core tools: ingest_data and query_dataset_with_ai — push data in, then ask questions about it in plain language. Their affiliate team adds (31 Jul 2026) that one connection reaches the sources already set up in your Databox account — they put that at 130+ — rather than a separate MCP server for every platform.

Plan & price: Every paid plan — the feature comparison marks the MCP server as not included on Free. Use is metered: MCP queries draw on the same monthly AI credit pool as their Genie assistant, 500 credits on Analyst, 1,500 on Pro, 4,000 on Growth and custom above. The 14-day free trial runs on the Growth plan. Their affiliate team confirmed the paid-plan requirement to us in writing on 29 Jul 2026.

HubSpot Live

Two servers. A hosted remote server at mcp.hubspot.com gives any MCP client read and write access to CRM records, marketing and content objects and full activity history over OAuth 2.1 with PKCE; a local Developer MCP server drives the HubSpot Developer Platform through the CLI.

Plan & price: Their changelog: the remote server graduated from beta and is "generally available to all HubSpot accounts" as of 13 April 2026. No separate price is named, your existing HubSpot permissions apply, and accounts with sensitive data switched on have activity objects blocked from the server.

Their docs →Their GA changelog →Our dossier Visit HubSpot

Plan & price: Not stated. Their page gates on role rather than plan, and points you at support if you want early access.

Their docs →Our dossier Visit Hubstaff

Jotform AI Agents Live

Server at mcp.jotform.com: create forms and read submissions, with an OAuth consent screen per user.

Plan & price: Their own FAQ answers it: "Is the MCP free? Yes, the MCP server is available at no additional charge. Your existing Jotform plan limits and features remain in effect." Enterprise adds higher rate limits (up to 600 requests a minute), white-labelling of the MCP App and SSO.

Their docs →Our dossier Visit Jotform AI Agents

Keeper Security Live

Server for AI agents over Keeper Secrets Manager, shipped as a Docker image and a Node build: list, search and retrieve secrets, create and update entries, handle file attachments, generate passwords and TOTP codes. Agents are scoped to named vault folders and sensitive operations prompt for human confirmation.

Plan & price: Not stated on their MCP pages. Their adjacent AI Agent Kit page does require "a Keeper Security account (Business or Enterprise)", but that is a different artifact, so we are not reading it as the server's plan.

Their docs →Our dossier Visit Keeper Security

lemlist Live

Server at app.lemlist.com/mcp: create, update, start and pause campaigns and sequences, manage leads, enrich emails and read team analytics.

Plan & price: Price not stated; enrichment operations (email finding, verification, phone enrichment) do consume credits.

Their docs →Our dossier Visit lemlist

MeetGeek Live

Two servers: a cloud one over OAuth with no API key or local install, and an open-source self-hosted Node build that runs on your machine with your own API key. Search meetings, pull transcripts, summaries, highlights, action items and analytics.

Plan & price: Their requirements list, in as many words: "A MeetGeek account (the Free plan works)." The paid plans they do name are the AI client's — Claude Pro, Team or Enterprise, ChatGPT Plus, Team or Enterprise.

Their docs →Our dossier Visit MeetGeek

Miro Live

Server at mcp.miro.com: read and build boards — frames, sticky notes, shapes, cards, tables, architecture and sequence diagrams, plus reading and resolving comments.

Plan & price: Enterprise. An admin has to enable the MCP server for the organisation before anyone can connect.

Their docs →Our dossier Visit Miro

monday.com Live

Hosted server covering boards, items, updates and workspace data, discoverable through a machine-readable card at monday.com/.well-known/mcp.json.

Plan & price: Their own FAQ, in two sentences: "MCP is currently available for all monday.com plans" and "There is currently no additional cost to use monday MCP." They add the caveat most vendors leave out — you may still pay the AI client you run it from.

Their docs →Our dossier Visit Pylon

QuickBooks UK Live

Local server from Intuit's own GitHub organisation, run as a stdio subprocess and published as an npm package: 144 tools across 29 entity types with full create, read, update, delete and search, plus 11 financial reports including balance sheet, P&L and cash flow. OAuth against a sandbox company or, once you have completed the production handshake, your live QuickBooks Online company.

Plan & price: Not stated. Intuit's repository says nothing about which QuickBooks plan the server needs or whether it costs extra. Their separate Claude connector — which Intuit nowhere calls MCP — does require an active QuickBooks or Intuit Enterprise Suite subscription and is US-only for now.

Their docs →Their Claude connector page →Our dossier Visit QuickBooks UK

Replit Beta

Three tools — create_app_from_prompt, update_app_using_prompt and ask_question — letting an MCP client drive Replit Agent to build real apps.

Plan & price: Works with a Free, Core, Pro or Enterprise account. What the underlying Agent runs cost is not specified in that documentation.

Reply.io Live

Reply MCP: een officiële, live remote server op mcp.reply.io met 70 tools over sequences (16), contacten (8), inbox en gesprekken (3), de Jason AI SDR (31), taken (3), workspace-resolvers (5) en help/meta (4). Elke tool draagt een veiligheidslabel — 31 zijn readOnlyHint, 39 destructiveHint — zodat een client kan aftoppen vóór er iets met gevolgen draait. Streamable HTTP (JSON-RPC 2.0 over SSE), MCP-protocol 2025-06-18. Inloggen met een scoped persoonlijke API-sleutel (Authorization: Bearer) waarop je per gebied rechten zet, of met OAuth voor clients die geen headers ondersteunen — OAuth geeft wel meteen de volledige toolcatalogus. Limiet ~3000 calls per uur.

Plan & price: Niet vermeld in hun eigen documentatie. Reply schrijft alleen dat MCP en de REST-API twee oppervlakken op één product zijn: hetzelfde account en hetzelfde creditsysteem. Er staat geen plan-eis of prijs voor de MCP-server zelf; je hebt wel een Reply.io-API-sleutel nodig.

respond.io Live

Server run locally over stdio or as an HTTP service, published as an npm package: retrieve, create and update contacts, send messages, WhatsApp templates and email, assign and close conversations, and manage custom fields, tags and internal comments.

Plan & price: Not stated. You need a Developer API access token from your workspace settings; their page says nothing about which plan includes one.

Their docs →Our dossier Visit respond.io

Rippling Live

Built on Code Mode rather than one tool per API: the agent searches a catalog of functions and executes code against them, across HR, IT, Time and Payroll. Rippling puts the token cost of a typical task at 98% below wrapping their 238 APIs as tools.

Plan & price: Not stated in their own announcement.

Their docs →Our dossier Visit Rippling

RocketReach Live

Server at mcp.rocketreach.co/mcp over OAuth 2.1: search 700M+ professional profiles and companies, look up contact details for a person or company, and read your own plan and credit balance.

Plan & price: Price not stated. Their docs require "a RocketReach account with API access" and list the credit cost per tool: searches and status checks cost nothing, a person lookup costs one lookup plus one export credit, a company lookup one company export credit.

Their docs →Our dossier Visit RocketReach

Runpod Live

Two servers: an API server for pods, endpoints, templates and volumes (needs an API key), and a docs server at docs.runpod.io/mcp that needs no authentication at all.

Plan & price: Not stated in their own documentation.

Their docs →Our dossier Visit Runpod

Seamless.ai Live

Hosted server at mcp.seamless.ai/mcp: 54 tools across 11 domains — contact and company search, research and enrichment, lists, saved searches, campaigns, tasks, templates, email drafts and sends, call logging and the activity feed — plus 7 read-only seamless:// resources for credit balance, templates and email accounts. Every tool carries a read, write or destructive label so the client can ask before anything with side effects runs. OAuth 2.1, or an API key for clients without it.

Plan & price: Split by licence, not by price: search, research, lists, saved searches and the credit/user lookups are open to all users; campaigns, tasks, templates, email, calls, activity and Connect config need a Connect licence, with campaigns and tasks needing Connect (full). MCP also has to be switched on for the account. No price for the MCP server itself is published.

Their docs →licence matrix per tool domain →Our dossier Visit Seamless.ai

Serpstat Live

Two builds of the same server: a hosted HTTP endpoint you authorise once with OAuth and use from web, desktop and mobile, or a local Node.js STDIO build where the API token never leaves your machine and you pick which tool groups to load. 63 SEO tools — keyword research, competitor gaps, backlink audits, site audits and rank tracking.

Plan & price: Team plan and above. Their own plan comparison lists "API, ChatGPT and Claude Integration (MCP)" as a Team feature and marks API access as absent on the Individual plan below it. Use is metered: every query spends Serpstat API credits at standard API pricing — 100 credits for 100 domain keywords, 5 for a backlinks summary. The 7-day trial includes full API access.

ServiceM8 Live

Server connecting ChatGPT or Claude to jobs, scheduling and client data for field-service work — a custom app on ChatGPT's side, a custom connector on Claude's.

Plan & price: Not stated for ServiceM8 itself. What they do say about availability points elsewhere: it "depends on the ServiceM8 MCP tool list, your AI platform's plan and settings, workspace admin controls, and action permissions."

Shippo Live

Server at mcp.shippo.com: compare carrier rates, buy labels, track packages, validate addresses and handle customs.

Plan & price: Works across all plan types. Reads — rates, address validation, tracking — cost nothing; buying a label charges your live account and asks for confirmation first.

Their docs →Our dossier Visit Shippo

Similarweb Live

Hosted server at mcp.similarweb.com: website and keyword analysis, app-market data across iOS and Android, Amazon seller and product data, and lead enrichment from digital behaviour.

Plan & price: Stated plainly: a "Similarweb subscription with API access: API-only, Business, or Enterprise plans", plus an active API key from your account settings. Metered too — "MCP uses the same data credits as standard API calls", and a chattier agent that pulls several endpoints spends more of them.

Their docs →Their MCP page →Our dossier Visit Similarweb

Softr Live

Server at mcp.softr.io/mcp: 20 tools across databases, tables and records — read and write, over OAuth or a personal API token.

Plan & price: Not stated in their own documentation.

Their docs →Our dossier Visit Softr

StoreSEO Live

Server at mcp.storeseo.com/mcp for their Shopify SEO app: connect a store through a pop-up that lets you pick the store and scope what the assistant may do, then optimise product listings, generate image alt text and fix meta descriptions from a prompt.

Plan & price: Not stated in their own documentation.

Their docs →Our dossier Visit StoreSEO

Storylane Live

Server over interactive demos: read demo analytics — views, unique visitors, session duration, CTA clicks, completion rate — list engaged accounts and captured leads, browse the demo library across workspaces, and list AI voices. Every tool is scoped to the data your own account can see.

Plan & price: Not stated. Their page does discuss Free, paid and company accounts, but those are ChatGPT's account tiers governing custom connectors, not Storylane plans — a distinction worth reading carefully before you assume you are gated.

Their docs →Our dossier Visit Storylane

Sunsama Live

Hosted server at api.sunsama.com/mcp over OAuth, connectable from ChatGPT's plugin directory or as a custom connector, letting an assistant work with your tasks and daily plan.

Plan & price: Not stated. The plan labels on their page — Claude Pro/Team, Notion paid — belong to the client you connect from, not to Sunsama.

Their docs →Our dossier Visit Sunsama

Survicate Live

Remote server over the whole feedback loop: list surveys and their questions, pull survey and per-question results (response and completion counts, answer distributions, NPS and CSAT) over a date range, search the responses, read and start AI research projects, and draft a survey that lands in the panel for review before launch. One-click OAuth, no API keys; every call runs as the connected user, so workspace role, folder access and Research Hub role apply as they do in the panel.

Plan & price: Not stated in their own documentation — the only subscription their help centre names is that of the AI assistant you connect from.

Their docs →Our dossier Visit Survicate

Tenable Live

Hexa AI MCP at cloud.tenable.com/mcp: 90 structured tools over the Exposure Data Fabric — assets, vulnerabilities, dashboards and scans.

Plan & price: Requires a Tenable One Foundation or Tenable One Advanced licence. Paid only, and not available in FedRAMP Moderate environments.

Their docs →Our dossier Visit Tenable

Todoist Live

First-party server at ai.todoist.net/mcp, plus a Todoist plugin that wires up the configuration for you.

Plan & price: Not stated for Todoist itself; their guide does note that Claude Code requires a paid Claude plan.

Their docs →Our dossier Visit Todoist

Wati Live

Wati MCP: one connection that lets Claude or ChatGPT manage contacts, send WhatsApp campaigns, read past chats and build AI agents in plain language. Sends go out on the same official number and approved templates, and the full history stays in the Wati dashboard.

Plan & price: Free for all current paid Astra customers, with no usage cap during launch. New customers get full MCP access on every Astra plan.

Their docs →Our dossier Visit Wati

Webflow Live

Open-source server over their Data, Designer and Browser APIs: manage sites and pages, read and write freeform custom code, handle registered scripts and custom fonts. A few capabilities only work with the Designer open and the Bridge App connected.

Plan & price: Not stated in their own documentation.

Their docs →Our dossier Visit Webflow

Wistia Live

Server for uploading video, making bulk updates, managing access and reading performance data from your agent. Every action asks for approval by default; you can set a tool to always-approve or block it.

Plan & price: Their FAQ: "All Wistia accounts have access to Wistia's MCP server... no upgrade needed." Anything you can do in the app you can do through the server; you only upgrade for more product features. Restricted by role rather than plan — owners and managers only.

Their docs →Their setup guide →Our dossier Visit Wistia

Woodpecker Live

Hosted remote server at api.woodpecker.co/mcp/v1: paste the URL into your AI client, sign in to Woodpecker and approve — no API key and no local server. Manage campaigns, prospects, email sequences, mailboxes and campaign reporting in natural language, and set each tool to run automatically, ask for approval, or not at all. A local Docker build authenticated with an API key exists as well, and their docs name it the only route to Agency client accounts: the hosted server cannot select an account managed under an Agency.

Plan & price: Their pricing page lists MCP Server inside the paid Integrations add-on, next to Claude, Clay, API, Webhooks and CLI — not in the base plan. The docs page itself states no plan.

Their docs →Integrations add-on on their pricing page →Our dossier Visit Woodpecker

Wrike v2 in beta

Query projects, manage tasks and navigate folders from Claude, ChatGPT, Copilot or Cursor.

Plan & price: Not stated in their own documentation.

Their docs →Our dossier Visit Wrike

Xero Live (remote server in beta)

Open-source local server connecting an LLM to Xero accounting data, part of an AI toolkit that also ships a CLI and OpenAI Agents SDK and LangChain integrations. A hosted remote server exists too, but only as a closed beta under separate terms.

Plan & price: Not stated for the open-source server. The remote beta's own terms are blunter than most: "if the Software moves out of beta phase and is released commercially, you may need to pay for use of the final commercial product."

Their docs →Their remote-beta terms →Our dossier Visit Xero

Zendrop Live

Server for their dropshipping platform: search the catalog, request shipping methods and delivery windows per country, list and filter orders with tracking, pull revenue, profit and refund analytics, and trigger fulfilment behind a built-in confirmation step. Access runs on a token you generate, can scope to read-only and can revoke.

Plan & price: Their FAQ answers it directly: "Do I need a paid Zendrop plan to use the MCP server? You can get started free. Some features may require a paid plan depending on your store's volume and needs." No tier is named.

Researched 2026-07-28. MCP is moving fast — check the source link before you commit to anything. Spotted a partner we missed, or a page that has changed? Tell us and we'll fix it.

Who does it best — and for what price

First, the honest framing, because a lot of "best MCP server" content gets this wrong: for almost every tool here, the MCP server is not a product you buy. It is a door onto a subscription you already pay for. So ranking them by price is mostly meaningless. What is worth ranking is the door: can you open it on the plan you are actually on, how often can you use it, and will it let you write as well as read.

Our own count, from the 74 vendor pages linked above.

Best if you're not paying anything yet — beehiiv and ClickUp

Both put the server on every plan including free. beehiiv is explicit that all users get it with no upgrade, with free plans read-only and writes requiring a paid plan — an honest, legible split. ClickUp is on all plans too and publishes its actual rate limits: 50 calls a day on Free, 300 on Unlimited and above. Published limits are rarer than they should be, and they are what tells you whether the thing is usable.

13 of the 74 are stated to work without a paid plan at all: Beehiiv, Bright Data, ClickUp, ElevenLabs, Gamma, HubSpot, Jotform AI Agents, MeetGeek, monday.com, Plesk, Replit, Wistia, Zendrop — though "free plan" and "free to run" are different promises, and each row above says which one applies.

Best free allowance for real work — Bright Data

5,000 requests a month on every new account, stated in writing. For an agent that needs to read the live web that is a genuine working budget rather than a demo, and it is the only server in this list that quantifies a free tier that precisely.

Best "your existing plan just works" — Apollo

Their documentation says plainly that there is no additional cost to connect and that your existing plan, permissions and credits still apply. That is exactly the sentence a buyer needs. Note the tail of it though: enrichment through MCP spends the same credits it always did, so an agent left to enrich a large list will cost you real money quietly.

Best-designed guardrails — Shippo and Circle

Shippo separates free reads (rates, tracking, address validation) from actions that charge your live account, and asks for confirmation before buying a label. Circle keeps read tools always-allowed and routes every write through an explicit approval. When an AI is holding the pen, that distinction is worth more than any feature list.

Most gated — Bitscale, Circle, Freshservice, Miro, Seamless.ai, Serpstat, Similarweb, Tenable, Woodpecker

These 9 are the ones where the plan genuinely decides. Miro's is Enterprise and an admin must switch it on. Tenable's Hexa AI MCP needs a Tenable One Foundation or Advanced licence. Freshservice's is an Early Access Program on Enterprise, by request. Circle's needs Business or above and admin rights, though it costs nothing extra on top. Serpstat's is a Team feature — the Individual plan under it has no API access at all, and every query spends API credits on top. Seamless.ai splits by licence rather than price, so which tools you see depends on what your seat includes. If you are evaluating any of these because of MCP, check your tier before you get attached.

Where we can't give you a verdict

42 of these 74 vendors publish nothing about plan or price for their MCP server anywhere we could find on their own site. That is not a criticism of the servers — several are excellent — but we are not going to invent a price to fill a column. If pricing matters to your decision, ask them, and treat the silence as a question to raise rather than a detail to assume.

Update, 29 Jul 2026 — one column filled in. We took our own advice and mailed the vendors we had marked "not stated". Databox answered within a day: the MCP server is on every paid plan and not on the Free Forever plan. Their plan comparison says the same, and adds the part the email did not — MCP queries spend from the same monthly AI credit pool as their Genie assistant, so the allowance on your plan is the real limit. We had only checked their developer documentation, which still says nothing about plan or price; the answer was on the pricing page all along. Databox has moved out of this column and into the table above, sourced to both pages.

Update, 1 Aug 2026 — three we had missed. We re-ran every source link and, this time, also laid the official MCP registry against our partner list. The registry verifies a publisher's domain by DNS, so a match there is a strong first-party signal — and it surfaced three partners our manual sweep had walked past: Serpstat, Frase and Clutch. All three had a server before we published; we simply did not find their pages. They are in the count above now, checked the same way as the rest, on their own domains. We also mailed five vendors who say nothing about plan or price; so far only Databox has answered.

Update, 7 Aug 2026 — QuickBooks, and where we bent our own rule. Intuit maintains a QuickBooks Online MCP server in their own GitHub organisation: a local stdio server, 144 tools across 29 entity types, 11 financial reports, OAuth against a sandbox or your live company. We left it out at first, because our rule says the documentation has to sit on the vendor's own domain and no page on intuit.com calls it MCP — the customer-facing QuickBooks connector for Claude never uses the word. We have put it in anyway, because an official server in Intuit's own organisation is not a weekend project, which is what the rule was written to exclude. You should know that is a judgement call and not the same standard as the rest of the table. Intuit says nothing about which plan the server needs, so it joins the "not stated" column.

Update, 17 Aug 2026 — we re-checked the whole database, and our method was the problem. Every partner added since the last pass got the same treatment as the original 363, but this time we stopped guessing URLs and started looking: the official MCP registry, every vendor's sitemap, and their llms.txt. That turned up 21 first-party servers we had walked past — including Xero, CrowdStrike, monday.com, Amplitude, Similarweb, Wistia and Webflow, none of them obscure. The pattern is dull but worth saying out loud: our earlier sweep looked for docs at predictable addresses, and vendors do not keep them there. Xero's sits at /ai, CrowdStrike's at /falcon-mcp/. If you have been keeping your own list this way, it is probably short for the same reason.

Three things we found and deliberately did not count. A docs-search endpoint at docs.vendor.com/mcp is not a product server — it answers questions about the manual, and several vendors ship one. A blog post explaining MCP is not a server. And Zendesk is the interesting case: the "MCP Server" in their marketplace is built by Swifteq, a third party, while Zendesk's own MCP work is a client — it connects Zendesk out to other people's servers. That is the opposite direction, so it does not belong in this list.

Update, 1 Sep 2026 — one column filled in, five doc pages moved, eight servers added. Jotform now answers the question on their own developer page: "Is the MCP free? Yes, the MCP server is available at no additional charge." They move out of the silent column. Five source links had moved and are updated — Descript, Softr, Envoy and Todoist redirected, and Clay's developer docs dropped their MCP page altogether, so we now cite the documentation on their own university site. Eight partners added to our database since the last sweep document a first-party server: HubSpot, Rippling, RocketReach, Bitscale, Castmagic, Zendrop, Gixo and StoreSEO. Five more we left out on the same rule as before. Attribuly's own page says the server is "currently in development" with a waitlist, so there is nothing to check yet. Datarails writes about MCP for finance but ships no server of their own. PartnerStack has a glossary entry. BackupMaster's /mcp is a docs-search endpoint. And Intelis, Dondy and one Shopify app expose a Wix site MCP — that is Wix's platform endpoint on their marketing site, not something the vendor built.

Where MCP disappoints

An honest guide has to include the part the launch posts leave out.

"Has an MCP server" says nothing about quality. The gap between servers is enormous — a handful of well-described tools that return readable text versus 200 auto-generated endpoints that flood the context window. Tool count is a marketing number, not a quality signal. Bybit ships 206 tools; that is impressive engineering and also a lot of surface area for a model to get lost in.

Beta means beta. 12 of the servers here are labelled beta, early access or "under active development" by the vendors themselves. Plesk's own announcement says to expect bugs and not to use it in production. That is admirable candour, and you should take it literally.

Permissions are inherited, not designed. A server usually gives the model whatever the authenticated user can already do. That is the right default, but it means an over-permissioned account becomes an over-permissioned agent. Gusto's advice to run its server in an isolated session — away from other MCP servers — is the sanest security note any vendor in this list publishes, and it applies well beyond Gusto.

Read is solved; write is not. Most of the value shipped so far is retrieval. Navan is read-only with writes "coming"; Gusto is read-only by design; ClickUp won't delete. The genuinely agentic use cases are still early, and the vendors being cautious are, we think, the ones getting it right.

Frequently asked questions

What is MCP in simple terms?

MCP (Model Context Protocol) is an open standard for connecting an AI assistant to a tool or data source. The AI app is the client, the tool ships a server, and the two speak one protocol. It means a tool builds one integration instead of one per AI app, and you can plug your own data into the assistant you already use.

Is MCP free?

The protocol itself is open and free. Whether a vendor's MCP server is free depends on the vendor. Of the 74 partner servers we checked, 32 state a plan or price in their own docs and 42 say nothing at all. Where a plan is stated, the MCP server is usually included with the subscription you already pay for rather than sold separately — the real limits are rate limits and whether writes are allowed.

Do I need to be a developer to use MCP?

Increasingly no. Remote servers are the norm now: you paste a URL into your AI client, approve an OAuth screen, and you're connected. Local servers still need a runtime — our own is a single Python file — but the setup is a copy-paste, not a project.

Is it safe to connect my CRM or payroll to an AI assistant?

Treat it like any other integration: it inherits your permissions, so scope it. Several partners are deliberately conservative — Gusto's server is read-only, Navan's is read-only for now, ClickUp refuses delete operations, and Circle requires per-action approval for writes. Gusto also advises running its server in an isolated client session rather than alongside other MCP servers.

Which MCP servers do you run yourself?

We publish one: the Honest Atlas MCP, a free server that gives any MCP client our hand-researched dossiers on 300 SaaS and AI tools — real pricing notes, the honest knock, who should skip it. It runs on your machine, needs no account and has zero dependencies.

Try ours in 30 seconds. The Honest Atlas MCP gives your assistant our dossiers on 300 tools — real pricing, the honest knock, who should skip it. Free, runs locally, no account. Or browse the same research as a human in the Honest Software Atlas, or take the open dataset.

How this page was made: we checked all 425 tools in our partner database against their own documentation — first on 2026-07-28, most recently on 2026-09-04 — and cite the vendor page for every claim. Plan and price wording is theirs, not ours; "not stated" means we could not find it published on their own site. Illustrations are our own SVGs; partner logos are hosted on our own servers, not hotlinked. Some links are affiliate links — we may earn a commission if you sign up, at no extra cost to you, and it never changes what we write: a tool that is gated or expensive gets said so on this page. Review content lives in our dossiers, which this page links to rather than repeats. How we review →

One honest email a week
