# Neo N3 MCP Improvements Applied
This document summarizes all the improvements and fixes applied to the Neo N3 Model Context Protocol project based on the comprehensive review.
## 🔧 Critical Fixes Applied
### 1. Fixed Testnet Asset Hash Inconsistency ✅
**File**: `src/services/neo-service.ts`
**Issue**: Testnet NEO asset hash was incorrect
**Fix**: Updated testnet asset hashes to match Neo N3 standards where NEO and GAS use the same contract hashes on both networks
```typescript
// Before (incorrect)
[NeoNetwork.TESTNET]: {
NEO: '0x8c23f196d8a1bfd103a9dcb1f9ccf0c611377d3b', // Wrong
GAS: '0xd2a4cff31913016155e38e474a2c06d08be276cf',
}
// After (correct)
[NeoNetwork.TESTNET]: {
NEO: '0xef4073a0f2b305a38ec4050e4d3d28bc40ea63f5', // Same as mainnet
GAS: '0xd2a4cff31913016155e38e474a2c06d08be276cf', // Same as mainnet
}
```
### 2. Fixed Version Mismatch ✅
**File**: `src/index.ts`
**Issue**: Server version was 1.4.0 but package.json shows 1.5.0
**Fix**: Updated server version to match package.json
```typescript
// Before
version: '1.4.0',
// After
version: '1.5.0',
```
### 3. Updated Default Testnet RPC URL ✅
**File**: `src/config.ts`
**Issue**: Using non-standard testnet RPC URL
**Fix**: Updated to use standard CoZ testnet RPC for consistency
```typescript
// Before
const DEFAULT_TESTNET_RPC = 'https://testnet1.neo.n3.nodereal.io';
// After
const DEFAULT_TESTNET_RPC = 'https://testnet1.neo.coz.io:443';
```
## 🚀 Enhancements Added
### 4. Enhanced Configuration with Rate Limiting ✅
**File**: `src/config.ts`
**Enhancement**: Added comprehensive configuration options for production deployments
**Added Features**:
- Rate limiting configuration
- Logging configuration
- Environment variable support for all settings
```typescript
// New configuration options
rateLimiting: {
enabled: process.env.RATE_LIMITING_ENABLED !== 'false',
maxRequestsPerMinute: parseInt(process.env.MAX_REQUESTS_PER_MINUTE || '60', 10),
maxRequestsPerHour: parseInt(process.env.MAX_REQUESTS_PER_HOUR || '1000', 10),
},
logging: {
level: process.env.LOG_LEVEL || 'info',
file: process.env.LOG_FILE || './logs/neo-mcp.log',
console: process.env.LOG_CONSOLE !== 'false',
},
```
