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
