### Current Implementation
🎯 Task: Set up CoinGecko API Server
📊 Progress: 100%
#### Changes Made
- ✅ Initialized Node.js project with `npm init -y`
- ✅ Installed correct CoinGecko API package (`coingecko-api-v3`) instead of non-existent `coingecko-server`
- ✅ Installed Express.js for server functionality
- ✅ Created server.js with basic API endpoints
- ✅ Created README.md with usage instructions
#### Technical Metrics
- Package Size: coingecko-api-v3 (2 packages)
- Dependencies: Express.js (69 packages)
#### Next Steps
1. 🔴 Test API endpoints with real data
2. 🔴 Add error handling and rate limiting
3. 🔴 Implement caching for API responses
## Task Progress - 2025-03-20 (Update)
### Current Implementation
🎯 Task: Enhance CoinGecko API Server with comprehensive endpoints
📊 Progress: 100%
#### Changes Made
- ✅ Implemented all endpoints from CoinGecko API Swagger definition
- ✅ Added proper parameter validation for required fields
- ✅ Organized endpoints into logical categories
- ✅ Updated README.md with comprehensive endpoint documentation
- ✅ Added proper error handling for all endpoints
#### Technical Metrics
- Endpoints Implemented: 30+ API endpoints covering all major CoinGecko API features

#### Next Steps
1. 🔴 Implement request rate limiting
2. 🔴 Add response caching to reduce API calls
3. 🔴 Create a dashboard for API monitoring
4. 🔴 Add authentication for private endpoints
## Implementation Notes - 2025-03-20
### CoinGecko API Server Enhancement
✨ Implemented Features:
- Basic Express server
* RESTful API endpoints for trending coins, coin prices, and detailed coin information
- CoinGecko API client integration
* Used coingecko-api-v3 package for API calls
🔧 Configuration:
```json
{
"timeout": 10000,
"autoRetry": true
}
```
📊 Commands Used:
```bash
npm init -y
npm install coingecko-api-v3
npm install express
```
## Implementation Notes - 2025-03-20 (Update)
### Comprehensive CoinGecko API Server
✨ Enhanced Features:
- Complete API coverage
* Simple price and token endpoints
* Comprehensive coin data endpoints
* Market charts and OHLC data
* Contract-based queries
* Asset platforms
* Categories
* Exchanges and tickers
* Derivatives
* NFTs (beta)
* Exchange rates
* Search functionality
* Trending data
* Global metrics
* Companies data
🔧 API Structure:
- RESTful design following CoinGecko official API patterns
- Query parameter validation
- Structured error responses
📊 Performance Considerations:
- Timeout handling for long-running requests
- Auto-retry for rate-limited responses
- Proper error propagation
# CoinGecko API Server Task Log
## Task Progress - March 20, 2023
### Current Implementation
🎯 Task: Implement MCP JSON-RPC 2.0 Support
📊 Progress: 100%
#### Changes Made
- ✅ Added JSON-RPC 2.0 endpoint for MCP communication
- ✅ Created schema definitions for MCP tools
- ✅ Implemented method handlers for all CoinGecko endpoints
- ✅ Created documentation for MCP integration
- ✅ Added test script for MCP integration
- ✅ Updated README with MCP information
#### Technical Metrics
- Added Dependencies: `jayson`, `node-fetch`
- New Endpoints: `/rpc`, `/mcp/schema`
- New Files: `mcp.js`, `mcp-schema.js`, `MCP_INTEGRATION.md`, `test-mcp.js`
#### Implementation Details
- Integrated JSON-RPC 2.0 middleware using `jayson` library
- Implemented fallback to free API when no API key is provided
- Added proper error handling for all RPC methods
- Created standardized schema for AI tool discovery
#### Commands Used
```bash
# Install dependencies
npm install --save jayson
npm install --save node-fetch@2
# Make test script executable
chmod +x test-mcp.js
# Test MCP integration
npm run test-mcp
```
#### Testing Verification
- Schema endpoint can be verified with:
```bash
curl -X GET http://localhost:3000/mcp/schema
```
- RPC endpoint can be tested with:
```bash
curl -X POST http://localhost:3000/rpc \
-H "Content-Type: application/json" \
-d '{"jsonrpc":"2.0","id":"1","method":"ping","params":[]}'
```
## Next Steps
1. 🔴 Add authentication for MCP endpoints
2. 🔴 Implement rate limiting for MCP requests
3. 🔴 Add more methods for additional CoinGecko endpoints
4. 🔴 Create automated tests for all MCP methods
