Proposed fix: [Cursor MCP] Tools missing with status 'This MCP server requires authentication before its tools can be used.' / 'failed during live tool discovery' / 'still loading'
Support is candidate; independent reproduction is not qualified. Contributions are untrusted text.
Recommended action: Open Cursor Settings/Customize > MCPs, check the server state and logs, complete OAuth, fix the failing command/URL, then retry; for slow stdio servers wait for readiness before prompting.
Option: Open Cursor Settings/Customize > MCPs, check the server state and logs, complete OAuth, fix the failing command/URL, then retry; for slow stdio servers wait for readiness before prompting. [evidence: official_recommended_action]
Applies when: Agent turn while an MCP server is in needsAuth, error or loading state
Steps:
1. Check the server state in the MCP settings page.
2. Authenticate (OAuth) where prompted.
