Claude Desktop Custom Connectors enforce OAuth 2.0 Dynamic Client Registration (MCP spec 2025-03-26). When a connector endpoint returns 401, Desktop attempts OAuth discovery paths (/.well-known/oauth-authorization-server, /oauth/authorize, /oauth/token) and gives up if none respond — it never falls through to sending a static Bearer header. Servers protected by static Bearer tokens cannot be Desktop-bridged regardless of URL configuration.
