## โ๏ธ Configuration
### ๐ **Configuration Files**
The server uses three types of configuration files:
1. **`error-debugging-config.json`** - Main server configuration (project root)
2. **`.error-debugging.json`** - Workspace-specific settings (workspace root)
3. **`.error-debugging-preferences.json`** - User preferences (home directory)
> **Note**: If no configuration file exists, the server automatically creates `error-debugging-config.json` with default settings when first started.
### ๐ง **Main Configuration**
Create `error-debugging-config.json` in your project root:
```json
{
"server": {
"name": "error-debugging-mcp-server",
"version": "1.0.0",
"logLevel": "info",
"maxConnections": 10,
"timeout": 30000
},
"detection": {
"enabled": true,
"realTime": true,

"excludePatterns": ["*.min.js", "*.map"]
},
"polling": {
"interval": 1000,
"maxRetries": 3
}
},
"analysis": {
"enabled": true,
"aiEnhanced": true,
"confidenceThreshold": 0.7,
"enablePatternMatching": true,
"enableSimilaritySearch": true

"enableConditional": true
}
},
"performance": {
"enabled": true,
"monitoring": {
"enabled": true,
"interval": 5000
}
}
}
```
> **Note**: If no configuration file exists, the server will automatically create `error-debugging-config.json` with default settings when first started.
### Workspace Configuration
For project-specific settings, create `.error-debugging.json` in your workspace root:
```json
{
"projectName": "my-project",
"rootPath": "/path/to/project",
"excludePatterns": ["node_modules/**", "dist/**", "*.min.js"],
"includePatterns": ["src/**", "lib/**"],
"languageSettings": {
"typescript": {
"strictMode": true,
"compilerOptions": {
"target": "ES2020"
}
},
"javascript": {
"eslintConfig": ".eslintrc.js"
}
}
}
```
### User Preferences
For personal settings, create `.error-debugging-preferences.json` in your home directory:
```json
{
"theme": "dark",
"notifications": {
"enabled": true,
"sound": false,
"desktop": true
},
"editor": {
"fontSize": 14,
"fontFamily": "Monaco",
"tabSize": 2
},
"debugging": {
"autoBreakOnError": true,
"showStackTrace": true,
"verboseLogging": false
}
}
```
## ๐ IDE Integration
### ๐ฏ **Tested & Working Configuration**
Use this **production-tested** configuration for seamless integration:
```json
{
"servers": {
"error-debugging": {
"command": "node",
"args": ["/path/to/error-debugging-mcp-server/dist/index.js"],
"env": {
"NODE_ENV": "development"
}
}
}
}
```
### ๐ฅ๏ธ **IDE-Specific Setup**
#### ๐ต **VS Code**
Add to your `settings.json`:
```json
{
"mcp.servers": {
"error-debugging": {
"command": "node",
"args": ["/path/to/error-debugging-mcp-server/dist/index.js"],
"env": {
"NODE_ENV": "development"
}
}
},
"mcp.enableLogging": true,
"mcp.logLevel": "debug"
}
```
#### ๐ก **Cursor IDE**
Create `~/.cursor/mcp-settings.json`:
```json
{
"servers": {
"error-debugging": {
"command": "node",
"args": ["/path/to/error-debugging-mcp-server/dist/index.js"],
"description": "Advanced error detection and debugging"
}
}
}
```
#### ๐ข **Windsurf IDE**
Add to Windsurf's MCP configuration:
```json
{
"mcpServers": {
"error-debugging": {
"command": "node",
"args": ["/path/to/error-debugging-mcp-server/dist/index.js"],
"env": {
"DEBUG": "mcp:*"
}
}
}
}
```
#### ๐ด **Augment Code**
Add to your Augment workspace configuration:
```json
{
"mcp": {
"servers": {
"error-debugging": {
"command": "node",
"args": ["/path/to/error-debugging-mcp-server/dist/index.js"],
"description": "Advanced error detection and debugging"
}
}
}
}
```
### โ
**Integration Verification**
After configuration:
1. **Restart your IDE** to apply settings
2. **Check MCP connection** in IDE logs
3. **Test with sample errors** using provided test files
4. **Verify tools are available**: `detect-errors`, `analyze-error`
## ๐ง Usage & Tools
### ๐ฏ **Available MCP Tools**
The server provides two powerful tools for error analysis:
#### ๐ **`detect-errors`**
Detects errors from various sources with intelligent filtering:
```json
{
"name": "detect-errors",
"description": "Detect errors from various sources (console, runtime, build, test)",
"parameters": {
"source": "console|runtime|build|test|all",
"language": "typescript|javascript|python|go|rust|php",
"files": ["specific/files/to/analyze"],
"includeWarnings": true,
"realTime": true
}
}
```
#### ๐ง **`analyze-error`**
Performs deep analysis of specific errors with AI-enhanced insights:
```json
{
"name": "analyze-error",
"description": "Perform deep analysis of a specific error",
"parameters": {
"errorId": "unique-error-identifier",
"includeContext": true,
"includeSuggestions": true,
"includeHistory": true
}
}
```
### ๐ **Error Detection Examples**
The server automatically detects and categorizes various error types:
```typescript
// 1. Type Safety Errors
const invalidCode: string = 123; // TS7006: Type mismatch
// 2. Null Safety Issues
function processUser(user: User | null) {
console.log(user.name); // TS18047: Possible null reference
}
// 3. Security Vulnerabilities
function executeCode(code: string) {
return eval(code); // SEC001: Security risk
}
// 4. Code Quality Issues
const unusedVariable = "test"; // TS6133: Unused variable
```
### ๐ฎ **Interactive Usage**
In your IDE's AI chat, you can use commands like:
```
๐ "Detect errors in the current file"
๐ง "Analyze the TypeScript error on line 42"
๐ง "Suggest fixes for null reference errors"
๐ "Show error statistics for this project"
```
