Check any remote MCP server

Listed or not: one probe, the quality checks and what the Claude and OpenAI directories require, in a few seconds. No account needed.

One credential-free, read-only probe; no tool is called. A few checks an hour without an account, more when you are signed in.

What happens

  • One probe from our servers: the protocol handshake (2026-07-28 server/discover or the older initialize), tools/list when it needs no sign-in, and the public OAuth metadata when it does.
  • We never send credentials, never call a tool and never reach private or internal addresses. URLs carrying credentials are refused.
  • The result gets a private link you can share; it is kept for 30 days and never listed or indexed.
  • Agents can run the same check through the REST API or the check_server tool of our MCP server.

Directory requirements come from the Claude and OpenAI documentation; a clean result does not mean a directory will accept a server, and no audit is implied. How the check works.
