MCP Registry
20,381 remote servers published on the official MCP Registry (registry.modelcontextprotocol.io) are imported daily and searchable when you add a tool. Each one is probed regularly: the catalogue tells you whether it answered, and whether it wants a credential or OAuth. Adding a server only succeeds once it answered our probe with the credential you gave.
OAuth and provider apps
Most OAuth servers register Clemali automatically (dynamic client registration or our client metadata document), so authorizing is one click. A few providers, GitHub and Slack among them, only accept pre-registered apps: for those, paste a personal token or API key, or use your own OAuth app credentials.
Custom servers
- URL — https only. Private addresses, localhost and cloud metadata endpoints are refused, including after a redirect.
- Transport — Streamable HTTP (default) or legacy SSE.
- Authentication — none, a bearer token (
Authorization: Bearer …), a custom header (X-API-Key: …) or OAuth. Extra headers can reference secrets by name with{{secret:NAME}}. - Timeout — 120 seconds by default, adjustable per server.
Status
Every server is probed when added, then every 30 minutes, and whenever a call fails. ok means it answered tools/list; needs authorization means it rejected the credential; unreachable means it did not answer. The status is shown in the Sources tab and in tool errors the agent receives.
