What the code does

Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Runs an external command src/utils/test-impact-analyzer.ts:51
      const diffOutput = execSync(

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

Kesslerio Attio MCP Server — questions

Answers built from our own checks of this server.

Is Kesslerio Attio MCP Server working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 0 of 91 checks got a reply (0.0%), average response time 423 ms. The bar chart above shows every period we have measured.
The registry lists Kesslerio Attio MCP Server as active — why does it not respond?
The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.
How do I connect Kesslerio Attio MCP Server?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Kesslerio Attio MCP Server need an API key?
No. Kesslerio Attio MCP Server completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. This is what we observed, not what the docs claim.
Is Kesslerio Attio MCP Server open source?
We cannot say either way: written in TypeScript, 69 stars on GitHub and 73 open issues, but we could not determine the licence, and without one the code is not open source by default.
