MCP Client Service Package

Provides infrastructure for communicating with MCP (Model Context Protocol)
servers. This is the foundation for AI agent tool integration.

Usage:
    from app.services.mcp import get_mcp_client, MCPClientManager

    # In FastAPI route
    async def my_route(mcp: MCPClientManager = Depends(get_mcp_client)):
        result = await mcp.call_tool("llm-gateway", "chat", {"prompt": "Hello"})

    # Direct usage
    manager = MCPClientManager()
    await manager.initialize()
    result = await manager.call_tool("issues", "create_issue", {...})
    await manager.shutdown()
