/api/v2/mcp-servers/{mcpServerId}/toolsDiscover tools on an enabled external MCP server and update connection metadata. Discovery is bounded by 1,000 tools, 5 MiB, 50 upstream pages, and 60 seconds; limits or later-page failures can return an unmarked partial inventory. Results are unpaginated and may be cached; refresh=true requests fresh discovery. Invalid OAuth returns 409 with MCP_SERVER_REAUTHORIZATION_REQUIRED; reauthorize in the browser. Disabled servers and servers requiring a managed Credential Group connection return 409; unavailable servers return 503. Requires workspace read access. HEAD checks access with the same authorization as GET but skips side effects, returning an empty 200 without payload headers on success. Workspace API keys return 403; use a personal API key or scoped OAuth token.
OAuth scope: api:write.
Authentication
Send a personal or workspace API key in X-API-Key. See key types and access; operations that reject workspace keys say so in their description.
Send X-API-Key in the request header.
Alternatively
Send a Sim OAuth access token in Authorization: Bearer. See OAuth authentication and scopes.
Authorization: Bearer YOUR_ACCESS_TOKEN
Required scopes: api:write

The caller lacks the rights this operation requires. When the cause is one a caller can act on, error.details.code names it. A resource in a workspace the caller cannot reach at all answers 404 instead, so absence and denial are indistinguishable.
