Master MCP Server

# Troubleshooting: Common Issues ## Config validation failed - Error shows `<path>: <reason>` from `SchemaValidator` - Verify your file is valid JSON/YAML - Check required fields under `master_oauth`, `hosting`, `servers` ## Missing TOKEN_ENC_KEY in production - Set `TOKEN_ENC_KEY` to a strong random string - In development, an ephemeral key is generated with a warning ## OAuth callback mismatch - Ensure `master_oauth.redirect_uri` matches your runtime base URL - If behind a proxy, set `MASTER_BASE_URL` to the external URL ## 401 Unauthorized to backends - Ensure client token is valid or delegated tokens are stored - For delegated flows, complete `/oauth/authorize` and `/oauth/callback` first ## Workers runtime odd redirects - Always set `hosting.base_url` in Workers to generate correct absolute URLs
