# Model Context Protocol (MCP) SDK Implementation
|
||
|
|
|
||
|
|
## Overview
|
||
|
|
This package implements a Model Context Protocol (MCP) server in Go that facilitates real-time communication between AI models and clients using Server-Sent Events (SSE). The implementation provides a framework for building AI-assisted applications with bidirectional communication capabilities.
|
||
|
|
|
||
|
|
## Core Components
|
||
|
|
|
||
|
|
### Server-Sent Events (SSE) Communication
|
||
|
|
- **Real-time Communication**: Robust SSE-based communication system that maintains persistent connections with clients
|
||
|
|
- **Connection Management**: Client registration, message broadcasting, and client cleanup mechanisms
|
||
|
|
- **Event Handling**: Event types for tools, prompts, and resources changes
|
||
|
|
|
||
|
|
### JSON-RPC Implementation
|
||
|
|
- **Request Processing**: Complete JSON-RPC request processor for handling MCP protocol methods
|
||
|
|
- **Response Formatting**: Proper response formatting according to JSON-RPC specifications
|
||
|
|
- **Error Handling**: Comprehensive error handling with appropriate error codes
|
||
|
|
|
||
|
|
### Tool Management
|
||
|
|
- **Tool Registration**: System to register custom tools with handlers
|
||
|
|
- **Tool Execution**: Mechanism to execute tool functions with proper timeout handling
|
||
|
|
- **Result Handling**: Flexible result handling supporting various return types (string, JSON, images)
|
||
|
|
|
||
|
|
### Prompt System
|
||
|
|
- **Prompt Registration**: System for registering both static and dynamic prompts
|
||
|
|
- **Argument Validation**: Validation for required arguments and default values for optional ones
|
||
|
|
- **Message Generation**: Handlers that generate properly formatted conversation messages
|
||
|
|
|
||
|
|
### Resource Management
|
||
|
|
- **Resource Registration**: System for managing and accessing external resources
|
||
|
|
- **Content Delivery**: Handlers for delivering resource content to clients on demand
|
||
|
|
- **Resource Subscription**: Mechanisms for clients to subscribe to resource updates
|
||
|
|
|
||
|
|
### Protocol Features
|
||
|
|
- **Initialization Sequence**: Proper handshaking with capability negotiation
|
||
|
|
- **Notification Handling**: Support for both standard and client-specific notifications
|
||
|
|
- **Message Routing**: Intelligent routing of requests to appropriate handlers
|
||
|
|
|
||
|
|
## Technical Highlights
|
||
|
|
|
||
|
|
### Configuration System
|
||
|
|
- **Flexible Configuration**: Configuration system with sensible defaults and customization options
|
||
|
|
- **CORS Support**: Configurable CORS settings for cross-origin requests
|
||
|
|
- **Server Information**: Proper server identification and versioning
|
||
|
|
|
||
|
|
### Client Session Management
|
||
|
|
- **Session Tracking**: Client session tracking with unique identifiers
|
||
|
|
- **Connection Health**: Ping/pong mechanism to maintain connection health
|
||
|
|
- **Initialization State**: Client initialization state tracking
|
||
|
|
|
||
|
|
### Content Handling
|
||
|
|
- **Multi-format Content**: Support for text, code, and binary content
|
||
|
|
- **MIME Type Support**: Proper MIME type identification for various content types
|
||
|
|
- **Audience Annotations**: Content audience annotations for user/assistant targeting
|
||
|
|
|
||
