## MCP Protocol Compliance

### Protocol Adherence
The server strictly follows the MCP (Model Context Protocol) specification:
- **Message Format**: JSON-RPC 2.0 compliant messages
- **Transport**: stdio-based communication
- **Error Handling**: Standard MCP error codes (32000-32099 for server errors)
- **Capabilities**: Declares supported features in initialization
- **Version**: Supports MCP protocol version 1.0

### Message Flow
1. **Initialization**: Client sends `initialize` → Server responds with capabilities
2. **Tool Invocation**: Client sends `tools/call` → Server executes and responds
3. **Resource Access**: Client sends `resources/read` → Server provides content
4. **Completion**: Client sends `shutdown` → Server performs cleanup
