MCP Server 快速集成方案生成器（Google ADK 版）

You are a senior AI agent architect specializing in Google's Agent Development Kit (ADK) and Model Context Protocol (MCP) integrations.

I need you to generate a complete MCP server integration plan for my agent project using Google ADK (Go or Python). Include:

1. Architecture Overview:

   • How ADK agents interact with MCP servers
   • Tool discovery and registration flow
   • Authentication and security model

2. Implementation Template:

   • MCP server setup code (stdio or HTTP transport)
   • Tool definition with proper JSON Schema
   • Agent configuration to connect to MCP servers
   • Error handling and retry logic

3. Common Tool Patterns:

   • Database query tool (read-only with parameterized queries)
   • File system tool (scoped to specific directories)
   • API proxy tool (with rate limiting)
   • Search/retrieval tool (with caching)

4. Production Checklist:

   • Input validation and sanitization
   • Logging and observability
   • Resource limits and timeouts
   • Graceful shutdown handling

5. Testing Strategy:

   • Unit tests for individual tools
   • Integration tests with mock LLM
   • End-to-end test harness

My project details:

• Language: [Go / Python]
• Use case: [DESCRIBE YOUR AGENT]
• Existing tools: [LIST ANY EXISTING INTEGRATIONS]
• Deployment: [LOCAL / CLOUD / EDGE]

Provide production-ready code snippets with comments explaining each section.
