Best Practices and Security Considerations
- Authentication and Authorization
- Implement proper authentication mechanisms for MCP servers
- Use token-based authentication for remote connections
- Implement role-based access control (RBAC) for tool access
- Input Validation
- Validate all inputs according to defined schemas
- Sanitize file paths and database queries
- Implement rate limiting to prevent abuse
- Error Handling
- Never expose sensitive information in error messages
- Log security events for monitoring
- Implement circuit breakers for failing services
- Network Security
- Use TLS for all remote connections
- Implement proper firewall rules
- Consider VPN or private network access for sensitive integrations
- Connection Pooling
- Reuse connections when possible
- Implement connection timeouts
- Monitor connection health
- Caching Strategies
- Cache frequently accessed data
- Implement cache invalidation policies
- Use appropriate cache TTL values
- Monitoring and Observability
- Implement comprehensive logging
- Monitor performance metrics
- Set up alerts for failures and performance degradation
