Troubleshooting

Authentication Failed

• Verify your token/session ID is valid

• Check organization slug is correct

• Ensure token has appropriate permissions

Connection Error

• Verify GLITCHTIP_BASE_URL is correct

• Check network connectivity

• Ensure GlitchTip instance is accessible

No Issues Found

• Verify issues exist in GlitchTip

• Check organization slug

• Ensure you have permission to view issues

Security

• Never commit .mcp.json, .cursor/mcp.json, or .env to version control

• Use .env files for storing secrets (automatically ignored by git if added to .gitignore)

• Use API tokens instead of session IDs for team usage

• Each developer should use their own credentials
