Check file permissions on database file - -**Database Corrupted** - -**Solution:** -```bash -# Backup database -cp ~/.tweakphp/database.db ~/.tweakphp/database.db.backup - -# Check database integrity -sqlite3 ~/.tweakphp/database.db "PRAGMA integrity_check;" - -# If corrupted, restore from backup or delete -rm ~/.tweakphp/database.db -# Restart TweakPHP to recreate database -``` - -**Disk Space Full** - -**Solution:** -```bash -# Check disk space -df -h - -# Clean up old execution history -# TweakPHP Settings → Clear History -``` - ---- - -## Error Code Reference - -| Error Code | Common Causes | Quick Fix | -|------------|---------------|-----------| -| `INVALID_PARAMETERS` | Missing or wrong parameter types | Check API documentation | -| `EXECUTION_ERROR` | PHP syntax error, missing extensions | Test code locally first | -| `TIMEOUT` | Code too slow, infinite loop | Increase timeout or optimize code | -| `CONNECTION_ERROR` | Connection not set, service down | Verify connection details | -| `NOT_FOUND` | Invalid connection ID | List available connections | -| `INTERNAL_ERROR` | Database error, unexpected exception | Check logs, restart TweakPHP | - ---- - -## Debugging Techniques - -### 1. Enable Verbose Logging - -Check logs for detailed error information: -```bash -tail -f ~/Library/Application\ Support/TweakPHP/logs/mcp-server.log | grep ERROR -``` - -### 2. Test Connections Manually - -Before using MCP, test connections directly: - -**Local:** -```bash -php -r "echo 'PHP works!';" -``` - -**Docker:** -```bash -docker exec my-container php -r "echo 'PHP works!';" -``` - -**SSH:** -```bash -ssh user@host "php -r \"echo 'PHP works!';\"" -``` - -### 3. Isolate the Problem - -Test each component separately: - -```typescript -// 1. Test server connection -const info = await client.callTool('get_php_info', { section: 'general' }) - -// 2. Test simple execution -const simple = await client.callTool('execute_php', { code: ' { - console.log('Testing MCP Server connection on localhost:3000...\n'); + console.log('Testing MCP Server connection on localhost:3000...\n') // Test 1: Check if server is listening const options = { @@ -16,53 +16,53 @@ const testConnection = () => { port: 3000, path: '/health', method: 'GET', - timeout: 5000 - }; + timeout: 5000, + } - const req = http.request(options, (res) => { - console.log('✅ Server is responding!'); - console.log(`Status Code: ${res.statusCode}`); - console.log(`Headers: ${JSON.stringify(res.headers, null, 2)}`); + const req = http.request(options, res => { + console.log('✅ Server is responding!') + console.log(`Status Code: ${res.statusCode}`) + console.log(`Headers: ${JSON.stringify(res.headers, null, 2)}`) - let data = ''; - res.on('data', (chunk) => { - data += chunk; - }); + let data = '' + res.on('data', chunk => { + data += chunk + }) res.on('end', () => { - console.log('\nResponse Body:', data); - testMCPTool(); - }); - }); - - req.on('error', (error) => { - console.log('❌ Server is not running or not accessible'); - console.log(`Error: ${error.message}`); - console.log('\nTo start the MCP server:'); - console.log('1.
