Troubleshooting

"Authentication required" error

Ensure you've run the auth server and completed browser authentication
Check that tokens are stored in ~/.sharepoint-mcp-tokens.json

"AADSTS7000215" error

You're using the Secret ID instead of the Secret Value
Go back to Azure and copy the actual secret value

"Access denied" error

Ensure admin consent was granted for the API permissions
Verify the site URL is correct
