EXPLAINED · WE RUN ONE OURSELVES

MCP, explained properly — and the 35 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 300 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 21 of the 35 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.

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 35 partners that ship an MCP server

We went through all 300 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. 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.

35 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".

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 35 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.

7 of the 35 are stated to work without a paid plan at all: ClickUp, Bright Data, Replit, ElevenLabs, Beehiiv, Plesk, Gamma — 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 — Miro, Tenable, Freshservice, Circle

These four 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. 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

21 of these 35 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.

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. Nine 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 35 partner servers we checked, 14 state a plan or price in their own docs and 21 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 300 tools in our partner database against their own documentation on 2026-07-28, 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.
