Discover MCP servers
A genuinely separate code path from any Persona listing. Mcp has no isPublic/visibility field, so unlike Agent/Skill/Knowledge there is no separate “public browse” subset — a bare Project credential OR a ProjectRuntimeContext without scope=mine both see every MCP in this Project’s own Domain, any owner type. scope=mine (ProjectRuntimeContext only) narrows to just that external user’s own MCPs.
Authorizations
Developer Platform Project credential, minted via POST /api/v1/projects/{projectId}/credentials. Send as Authorization: Bearer <keyId>.<secret>. Optionally pair with the x-persona-external-user-id header to act on behalf of one of the Project's own external users. This credential is a server-side secret — see the Integration Guide.
