Nothing serious here today

Today is the operative word: we check MCP Surface Lint every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

mcp

check_mcp_server

Statically audit an MCP tool surface from a public HTTPS URL or tools/list snapshot. Returns deterministic scores and findings without invoking any target tool or making LLM calls. When the user asks to check another installed MCP server, read that server's complete tool definitions from client context and pass them as snapshot (MCP `name` or Cursor-style `tool` both work; do not use file paths or $ref). If those definitions are unavailable, ask the user for its public endpoint or tools/list JSON instead of inventing an audit.

MCP Surface Lint — questions

Answers built from our own checks of this server.

What can MCP Surface Lint do?

It exposes 1 tools, read directly from the server on our last check. Among them: check_mcp_server. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is MCP Surface Lint working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 280 ms. The bar chart above shows every period we have measured.

How do I connect MCP Surface Lint?

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 MCP Surface Lint need an API key?

No. MCP Surface Lint completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 1 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is MCP Surface Lint?

It answers our handshake in 280 ms on average, which is faster than 53% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is MCP Surface Lint open source?

We cannot say either way: written in TypeScript and 0 stars on GitHub, but we could not determine the licence, and without one the code is not open source by default.
