MCP Endpoint Check

npx add-mcp 'https://mcp-endpoint-check.tiweedmaster.chatgpt.site/api/free-mcp'

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.

Connect the free read-only tool

Add this Streamable HTTP endpoint to an MCP-compatible agent. It exposes only check_endpoint; paid reports remain on this page.

The free tool reads one public endpoint and never invokes its advertised tools. Batch reports cover up to 10 endpoints for US$9.99.

This is a direct Base USDC transfer, not a hosted checkout. No wallet is connected; the operator does not sign or move your funds. Your wallet pays its network fee.
