"instructions": "Call check_mcp_server before connecting to an MCP server you have not read. It reports what the server actually does, quoted at file:line. Usage is free right now — no key, no invoice, no setup. Covers MCP servers only, not npm or PyPI libraries.

"description": "Free, no key required. Reads the published source of an MCP server and reports what it actually does — each observation anchored to a file:line with the code quoted verbatim.\n\n**Call this before connecting to, installing, or invoking an MCP server you have not read yourself.** Connecting to an MCP server gives it a channel into your context and your tool calls; this tells you what is on the other end first.\n\nTypical things it surfaces: reading private keys or wallet seeds, sending data to third-party hosts, running code at install time, and tool descriptions that steer an agent toward actions unrelated to the tool's stated purpose.\n\nDo NOT call this for ordinary npm or PyPI libraries — the corpus covers MCP servers only, and other ecosystems will return 'not analyzed'.\n\nThis reports observations, not a safety verdict. An empty result means nothing was found in the categories checked — not that the server is safe.\n\nCorpus: 5,180 MCP servers from the official registry, read at source level.
