Vouch does not always answer

Over the last week it answered 99.8% of our checks. We check every 15 minutes, so you hear about the next outage within the hour — not from your users.

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

vouch

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_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.

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 — questions

Answers built from our own checks of this server.

What can Vouch do?

It exposes 3 tools, read directly from the server on our last check. Among them: vouch_check, vouch_compare, vouch_find. 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 Vouch working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 92 checks got a reply (98.9%), average response time 382 ms. The bar chart above shows every period we have measured.

Is Vouch still maintained?

The linked repository no longer exists on GitHub — it was deleted or made private. We show this because it changes what you can expect: an unmaintained server may keep answering for months and then stop without warning.

How do I connect Vouch?

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 Vouch need an API key?

No. Vouch completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 3 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Vouch?

It answers our handshake in 382 ms on average, which is faster than 43% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
