Tools

Open a tool for its reasons and full description. Descriptions are the publisher's own words, shown as they are.

  • vouch_checkGet an MCP tool's independently measured trust score before relying on it: real invocation trials, not self-reported metadata.No findings

    Why it is in this group

    • The description's first verb is "get": a word for reading.
    Description, as the server wrote it
    Get an MCP tool's independently measured trust score before relying on it: real invocation trials, not self-reported metadata. Call this before adding a new MCP server to a project, or when deciding between two tools that do similar things. Look up by tool name, package, or server — free text.
  • vouch_compareCompare 2-5 MCP tools' measured behaviour side by side before picking one.No findings

    Why it is in this group

    • The name "vouch_compare" says "compare": a word for reading.
    Description, as the server wrote it
    Compare 2-5 MCP tools' measured behaviour side by side before picking one. Call this when weighing alternatives for the same task. Never collapses the comparison into a single ranked number — each tool keeps its own score and tier, and a caveat is surfaced when compared tools weren't measured at the same tier.
  • vouch_findSearch Vouch's independently measured corpus of MCP tools by free-text query.No findings

    Why it is in this group

    • The name "vouch_find" says "find": a word for reading.
    Description, as the server wrote it
    Search Vouch's independently measured corpus of MCP tools by free-text query. Call this when choosing an MCP tool for a task and you want options ranked by measured reliability rather than popularity — optionally filtered by measurement tier (deep = full behavioural battery, shallow = schema + sample-call only).

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
