MCP Endpoint Check
Read-only checks for public MCP endpoints: HTTPS reachability, initialization, tools/list schemas and latency. Offers a free one-URL check and a paid batch audit; it never invokes advertised tools.

Check what an MCP endpoint serves.
Get HTTPS reachability, the MCP initialize result, advertised tool names and input schemas, and response latency. The checker never invokes advertised tools.

What the report includes
- Reachability: public DNS screening, TLS response, status and latency.
- MCP: initialize handshake and tools/list output, when supported.
- Safety: no redirects, private destinations, URL credentials or tool calls.
DNS is screened before connection; the hosting platform performs the final DNS resolution, which can change after that check. Submit only public endpoints you are authorized to inspect.
