Troubleshooting

MCP servers not connecting?

• Check Node.js is installed: docker compose exec mcpjungle-gateway node --version
• Verify credentials are set (GITHUB_TOKEN, NOTION_API_KEY)
• Check logs: docker compose logs mcpjungle-gateway | grep -i mcp

Authentication errors?

• Verify API key format: Bearer sk-xxx
• Check key exists in API_KEYS environment variable

Permission denied?

• Check your role: GET /mcp/acl/role
• Verify role has permission in configs/mcp-acl.yaml

Next Steps

1. Configure Credentials: Set GITHUB_TOKEN and NOTION_API_KEY
2. Customize Roles: Edit ACL configuration for your needs
3. Test Integration: Run test suite to verify setup
