Vouch — independently measured reliability scores for MCP tools, not self-reported claims.
Server tool list (3)
Raw names from tools/list. Only developers need these.
| vouch_check | 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_find | 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). |
| vouch_compare | 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. |
