What these figures do not show
- A passing check means the server completed the MCP handshake with us (initialize, then tools/list, with no credentials; mcp-handshake/2) or asked for credentials first (HTTP 401). It does not show that the server's tools work or what they return. Tool names are as the server listed them.
- Listed in the Official MCP Registry; this data comes from the Official MCP Registry. Its listing's description is not republished.
- Limited evidence: monitored for 1 day (less than 30).
