Attempting to connect to a local MCP Server, Accomplish calls GET /.well-known/oauth-authorization-server. Since this local service does not require authorization, the MCP Server responds with a 404. Accomplish can not connect.
Run a local MCP Server with no required Authorization/Authentication. Accomplish fails to connect.
Expected Behavior
Accomplish handles the 404 and attempts to query the service endpoint(s) anyway and only then determines whether to consider the service available. Auth failures would not be reported as a 404 in any case.
Environment
Accomplish 0.4.14 on Windows 11. MCP Server on LAN-based VM.
