What the code does

We read the source, 20 h ago · rules 3dff92dd89df

Evidence

Things with no honest explanation: a promise that contradicts the code, code that runs at install time while hiding what it does, data leaving the machine.

Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

VouchSpec Agent Skill Evidence — questions

Answers built from our own checks of this server.

Why is there no tool list for VouchSpec Agent Skill Evidence?
The server answered our handshake with an authorization challenge, so it is running — but it will not describe its tools to an anonymous client. To see them you need to connect with your own credentials. We record it as alive, not as broken: 100.0% of checks in the last 24 hours got a reply.
Is VouchSpec Agent Skill Evidence 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 230 ms. The bar chart above shows every period we have measured.
How do I connect VouchSpec Agent Skill Evidence?
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. You will need your own credentials: it refuses anonymous clients.
Does VouchSpec Agent Skill Evidence need an API key?
Yes. Every time we knock, VouchSpec Agent Skill Evidence answers with an authorization challenge instead of its tool list — that is how we know it is running and gated rather than broken. Bring your own credentials and it will talk.
How fast is VouchSpec Agent Skill Evidence?
It answers our handshake in 230 ms on average, which is faster than 61% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
Is VouchSpec Agent Skill Evidence open source?
We cannot say either way: written in HTML and 1 stars on GitHub, but we could not determine the licence, and without one the code is not open source by default.
