# Check an MCP server

Paste the URL of a remote MCP server, listed or not, at /check: one credential-free probe, the quality checks and the readiness for the Claude and OpenAI directories, in seconds.

- The probe never sends credentials, never calls a tool and never reaches private or internal addresses; URLs carrying credentials are refused.
- Each result gets a private link (kept 30 days, never listed or indexed) with a Markdown twin at /check/{id}.md.
- A few checks per hour without an account, more with an API key.

## For agents

```
curl -X POST 'https://api.protogrid.dev/v1/check?wait=25' -H 'content-type: application/json' -d '{"url":"https://mcp.example.com/mcp"}'
curl 'https://api.protogrid.dev/v1/check/{id}'
```

Or call the `check_server` tool of the MCP server at https://api.protogrid.dev/mcp.
