Issue
When attempting to connect GitHub Copilot to the public MCP endpoint `nordicsemi.mcp.kapa.ai` (as described in the [Kapa.ai MCP integration docs](docs.kapa.ai/.../overview, I'm encountering an authentication error.
CFG
- MCP URL: `nordicsemi.mcp.kapa.ai`
- Copilot client: GH Copilot for VS Code / GH Copilot CLI
- Auth flow: Standard Google sign-in (public MCP, no API key)
ERR
1. When triggered by Copilot, the auth flow opens a browser window with a redirect to:
`127.0.0.1:35001/
2. The page displays: "Authorization Failed / An unexpected error occurred."
3. Unable to complete authentication; MCP connection in Copilot fails.
ENV
- Copilot Environment: GH Copilot VS code / GH Copiilot CLI
- MCP URL: `nordicsemi.mcp.kapa.ai`
- OS: Linux
How to reproduce
1. Configure Copilot MCP URL as `nordicsemi.mcp.kapa.ai`
2. Trigger an MCP action (e.g., ask a question)
3. Complete the Google sign-in prompt
4. Receive the local callback error: `127.0.0.1:35001/
Could you please investigate the authorization failure on the public MCP endpoint? If you need additional logs or authentication details, let me know how to collect them.
Thanks in advance!
