# Implementation Notes
## Overview
This MCP server implements the Model Context Protocol for Google's Gemini API. It provides a standardized way for Claude Desktop to interact with Gemini models.
## Protocol Implementation
### Initialization Flow
```typescript
// Client sends initialize request
{
"jsonrpc": "2.0",
"id": 1,
"method": "initialize"
}
// Server responds with capabilities
{
"jsonrpc": "2.0",
"id": 1,
"result": {
"protocolVersion": "2024-11-05",
"capabilities": {...}
}
}
```
### Content Generation
```typescript
// Client sends generation request
{
"jsonrpc": "2.0",
"id": 2,
"method": "generate",
"params": {
"prompt": "Hello, world!"
}
}
// Server responds with generated content
{
"jsonrpc": "2.0",
"id": 2,
"result": {
"type": "completion",
"content": "Generated text..."
}
}
```
## Key Components
1. WebSocket Server
- Handles client connections
- Manages message routing
- Implements protocol lifecycle
2. Gemini Integration
- Model initialization
- Content generation
- Error handling
3. Message Processing
- JSON-RPC parsing
- Protocol validation
- Response formatting
## Security Considerations
1. API Key Handling
- Environment variables only
- No logging of sensitive data
- Secure key rotation support
2. Input Validation
- Request format validation
- Parameter sanitization
- Error boundary handling
## Performance
1. Connection Management
- Single WebSocket connection
- Efficient message routing
- Resource cleanup
2. Error Handling
- Graceful error recovery
- Detailed error messages
- Proper status codes
