Security profile

Claimed and verified servers get a weekly static scan that shows what the code can reach: external services, environment variables, shell commands, agent configuration folders, plus any dependencies with known advisories. Claim this listing to get one. How the security profile works

Documented tools (4)

From project documentation. A server handshake does not verify each tool’s description or behavior.

echo

plain tool.

get_weather

a valid x-mcp-header: "City" annotation on its city argument.

invalid_header_tool

an annotation using the header name "Bad Header". The space makes it an invalid RFC 9110 token, so the whole tool definition is invalid.

trigger_invalid_params

answered with a real -32602 Invalid params error whose message is not about a missing tool.
