Bug Report: CIMD is unavailable because the server did not advertise CIMD support
`Steps to Reproduce`
- Create an MCP server that advertises /.well-known/oauth-protected-resource/mcp
- Which points to an OAuth authorization server
- Which has metadata at /.well-known/oauth-authorization-server
- Which advertises CIMD support via client_id_metadata_document_supported
- Add it to ChatGPT
`Expected Result`
CIMD based OAuth works
`Actual Result`
Received error "CIMD is unavailable because the server did not advertise CIMD support."
`Environment`
Firefox on Ubuntu, though User-Agent seems irrelevant
