What we verify
We read the real schemas
We open a live MCP session, run the handshake and read every tool schema from the server itself. Nothing on this page is a publisher's description of their own server.
Live example: xyz.mindjack/mcp
We check TLS and OAuth
We read the certificate chain, the OAuth metadata and whether the call path needs a token. A README shows none of that.
Live example: VerifyMCP
We rescan daily
We resolve each package's production dependency tree against OSV and rescore every server daily, so a tool set that changes under you shows up here.
Live example: Canvas API MCP
