### 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`
