Try it

Call this server's tools from your browser. Nothing to install.

https://api.protogrid.dev/mcp

Requests go through mcptry because browsers can't call most MCP servers directly. Header values are sent to the server for that request only and are never stored or logged.

Tool list from our last check. Connect live to refresh it.

check_server

Probe a remote MCP server URL once, credential-free and without calling its tools, and get its quality checks and its readiness for the Claude and OpenAI directories. Pass `url` to start a check (waits up to 25 s for the result), or `id` to read one. Quota: a few checks per hour anonymously, more with an API key.

idstring

A check id returned earlier, to read its result

urlstring

The server's streamable HTTP or SSE URL, e.g. https://mcp.example.com/mcp. Never include credentials.

waitinteger

Seconds to wait for the result (default 25)

This tool isn't marked read-only, so it may change something on the server or in an account you connected.

I understand, run it anyway
