Three bugs fixed to make the end-to-end OAuth flow work for OpenAPI MCP servers:
1. **Transport mapping in getTemporaryPayload**: `TRANSPORT.OPENAPI` is a UI-only concept;
the backend only accepts `"http"`, `"sse"`, or `"stdio"`. The pre-OAuth temp-session
call was sending `transport: "openapi"` and getting a 422. Fixed by mapping to `"http"`.
2. **deriveErrorMessage handles FastAPI 422 arrays**: FastAPI validation errors return
`detail` as an array of `{loc, msg, type}` objects. The shared error extractor was
returning the array directly, causing `Error: [object Object]`. Fixed to map each
item to its `.msg` field.
3. **Skip OAuth discovery when authorization_url already provided**: `build_mcp_server_from_table`
was unconditionally calling `_descovery_metadata(server_url)` for OAuth servers. For
OpenAPI servers the url is the spec JSON file, not the API base — this caused a timeout
fetching e.g. the GitHub spec (2 MB). Fixed by skipping discovery when `authorization_url`
is already set.
Also: collapsible auth section in MCP server form, "Create OAuth App →" link next to
Client ID when a docs URL is available (e.g. GitHub OAuth App creation page), and
`extractErrorMessage` helper in `useMcpOAuthFlow` for cleaner error display.
