# MRAPIDS-Agent MCP Server - Comprehensive Test Cases
## 🔍 Deep Review Summary
**MRAPIDS-Agent** is a Model Context Protocol (MCP) server that enables AI agents to safely execute API operations through MicroRapid. It implements a secure, policy-driven architecture with comprehensive rate limiting, authentication management, and audit logging.
### Key Architecture Components:
- **MCP JSON-RPC Server**: Runs on port 3333 by default
- **Policy Engine**: Rule-based access control with conditions
- **Rate Limiter**: Multi-tier token bucket implementation
- **Auth Manager**: Profile-based credential management
- **Audit System**: Structured JSON logging with rotation
- **Security Layer**: Prompt injection detection, response redaction
