+# MCP Server API Reference
+
+## Tool Handler Base Class
+
+All tools extend the `ToolHandler` abstract class which provides lifecycle management, validation, and error handling.
+
+### Class Definition
+
+```typescript
+abstract class ToolHandler<TInput = any, TOutput = any> {
+  constructor(
+    config: ToolConfig,
+    inputSchema: z.ZodSchema<TInput>,
+    outputSchema: z.ZodSchema<TOutput>
+  );
+
+  // Main execution method
+  async execute(input: unknown, context: ToolContext): Promise<TOutput>;
+
+  // Lifecycle hooks (override in subclass)
+  protected async initialize(): Promise<void>;
+  protected async validate(input: TInput): Promise<TInput>;
+  protected abstract handle(input: TInput, context: ToolContext): Promise<TOutput>;
+  protected async cleanup(): Promise<void>;
+  protected async checkPermissions(context: ToolContext): Promise<void>;
+}
+```
+
+### Tool Configuration
+
+```typescript
+interface ToolConfig {
+  name: string;          // Unique tool identifier
+  description: string;   // Human-readable description
+  timeout?: number;      // Execution timeout in ms (default: 30000)
+  permissions?: string[]; // Required permissions
+}
+```
+
+### Tool Context
+
+```typescript
+interface ToolContext {
+  requestId: string;     // Unique request identifier
+  permissions: string[]; // Granted permissions
+  userId?: string;       // Optional user identifier
+  metadata?: Record<string, any>; // Additional context
+}
+```
+
+## Creating a Custom Tool
+
+### Basic Example
+
+```typescript
+import { z } from 'zod';
+import { ToolHandler, ToolContext } from '@mcp/tools';
+
+// Define schemas
+const InputSchema = z.object({
+  message: z.string(),
+  uppercase: z.boolean().optional(),
+});
+
+const OutputSchema = z.object({
+  result: z.string(),
+  length: z.number(),
+});
+
+type Input = z.infer<typeof InputSchema>;
+type Output = z.infer<typeof OutputSchema>;
+
+// Implement tool
+export class EchoTool extends ToolHandler<Input, Output> {
+  constructor() {
+    super(
+      {
+        name: 'echo',
+        description: 'Echo a message with transformations',
+        timeout: 5000,
+      },
+      InputSchema,
+      OutputSchema
+    );
+  }
+
+  protected async handle(input: Input, context: ToolContext): Promise<Output> {
+    let result = input.message;
+    
+    if (input.uppercase) {
+      result = result.toUpperCase();
+    }
+
+    this.logger.info({ message: result }, 'Echoing message');
+
+    return {
+      result,
+      length: result.length,
+    };
+  }
+}
+```
+
+### Advanced Example with Permissions
+
+```typescript
+export class DatabaseQueryTool extends ToolHandler<QueryInput, QueryOutput> {
+  private db: Database;
+
+  constructor() {
+    super(
+      {
+        name: 'db_query',
+        description: 'Execute database queries',
+        timeout: 60000,
+        permissions: ['database:read', 'database:write'],
+      },
+      QueryInputSchema,
+      QueryOutputSchema
+    );
+  }
+
+  protected async initialize(): Promise<void> {
+    // Connect to database
+    this.db = await Database.connect(process.env.DATABASE_URL);
+  }
+
+  protected async checkPermissions(context: ToolContext): Promise<void> {
+    const isWrite = this.isWriteQuery(this.currentInput.query);
+    
+    if (isWrite && !context.permissions.includes('database:write')) {
+      throw new Error('Permission denied: database:write required');
+    }
+    
+    if (!context.permissions.includes('database:read')) {
+      throw new Error('Permission denied: database:read required');
+    }
+  }
+
+  protected async validate(input: QueryInput): Promise<QueryInput> {
+    // Additional validation beyond schema
+    if (this.containsSqlInjection(input.query)) {
+      throw new Error('Invalid query: potential SQL injection');
+    }
+    
+    return input;
+  }
+
+  protected async handle(input: QueryInput, context: ToolContext): Promise<QueryOutput> {
+    const startTime = Date.now();
+    
+    try {
+      const results = await this.db.query(input.query, input.params);
+      
+      return {
+        rows: results.rows,
+        rowCount: results.rowCount,
+        duration: Date.now() - startTime,
+      };
+    } catch (error) {
+      this.logger.error({ error, query: input.query }, 'Query failed');
+      throw new Error(`Database query failed: ${error.message}`);
+    }
+  }
+
+  protected async cleanup(): Promise<void> {
+    // Close database connection
+    if (this.db) {
+      await this.db.close();
+    }
+  }
+}
+```
+
+## Tool Registration
+
+### Registering Built-in Tools
+
+```typescript
+import { ToolRegistry } from '@mcp/registry';
+import { FileReadTool, FileWriteTool } from './tools';
+
+const registry = new ToolRegistry(natsClient);
+
+// Built-in tools are registered automatically
+// But you can also register manually
+registry.registerBuiltinTool('file_read', new FileReadTool());
+registry.registerBuiltinTool('file_write', new FileWriteTool());
+```
+
+### Registering External Module Tools
+
+```typescript
+// External tools are discovered via NATS
+// Modules announce their tools on startup
+natsClient.publish('tools.discovery', {
+  module: 'my-module',
+  tools: [
+    {
+      name: 'my_tool',
+      description: 'Custom tool from module',
+      inputSchema: { /* ... */ },
+      permissions: ['custom:permission'],
+    }
+  ]
+});
+```
+
+## Error Handling
+
+### Error Types
+
+```typescript
+// Base error class
+export class ToolError extends Error {
+  constructor(
+    message: string,
+    public code: string,
+    public details?: any
+  ) {
+    super(message);
+    this.name = 'ToolError';
+  }
+}
+
+// Specific error types
+export class ValidationError extends ToolError {
+  constructor(message: string, details?: any) {
+    super(message, 'VALIDATION_ERROR', details);
+  }
+}
+
+export class PermissionError extends ToolError {
+  constructor(message: string, required: string[]) {
+    super(message, 'PERMISSION_ERROR', { required });
+  }
+}
+
+export class TimeoutError extends ToolError {
+  constructor(timeout: number) {
+    super(`Operation timed out after ${timeout}ms`, 'TIMEOUT_ERROR');
+  }
+}
+```
+
+### Error Handling in Tools
+
+```typescript
+protected async handle(input: Input, context: ToolContext): Promise<Output> {
+  try {
+    // Tool logic
+  } catch (error) {
+    if (error.code === 'ENOENT') {
+      throw new ToolError('File not found', 'FILE_NOT_FOUND', { path: input.path });
+    }
+    
+    // Re-throw unknown errors
+    throw error;
+  }
+}
+```
+
+## Testing Tools
+
+### Unit Testing
+
+```typescript
+import { MyTool } from './MyTool';
+import { ToolContext } from '@mcp/tools';
+
+describe('MyTool', () => {
+  let tool: MyTool;
+  
+  beforeEach(() => {
+    tool = new MyTool();
+  });
+
+  const createContext = (permissions: string[] = []): ToolContext => ({
+    requestId: 'test-request',
+    permissions,
+  });
+
+  it('should execute successfully', async () => {
+    const result = await tool.execute(
+      { input: 'test' },
+      createContext(['required:permission'])
+    );
+    
+    expect(result).toEqual({ output: 'expected' });
+  });
+
+  it('should require permissions', async () => {
+    await expect(
+      tool.execute({ input: 'test' }, createContext())
+    ).rejects.toThrow('Permission denied');
+  });
+});
+```
+
+### Integration Testing
+
+```typescript
+import { ToolRegistry } from '@mcp/registry';
+import { NatsClient } from '@mcp/nats';
+
+describe('Tool Integration', () => {
+  let registry: ToolRegistry;
+  let nats: NatsClient;
+
+  beforeAll(async () => {
+    nats = new NatsClient();
+    await nats.connect();
+    registry = new ToolRegistry(nats);
+  });
+
+  afterAll(async () => {
+    await nats.close();
+  });
+
+  it('should execute tool via registry', async () => {
+    const result = await registry.executeTool(
+      'my_tool',
+      { input: 'test' }
+    );
+    
+    expect(result).toBeDefined();
+  });
+});
+```
+
+## Performance Considerations
+
+### Timeout Management
+
+```typescript
+protected async handle(input: Input, context: ToolContext): Promise<Output> {
+  // Use AbortController for cancellable operations
+  const controller = new AbortController();
+  
+  const timeoutId = setTimeout(
+    () => controller.abort(),
+    this.config.timeout || 30000
+  );
+
+  try {
+    const result = await fetch(input.url, {
+      signal: controller.signal,
+    });
+    
+    return processResult(result);
+  } finally {
+    clearTimeout(timeoutId);
+  }
+}
+```
+
+### Resource Management
+
+```typescript
+export class ResourceIntensiveTool extends ToolHandler {
+  private pool: ResourcePool;
+
+  protected async initialize(): Promise<void> {
+    // Initialize resource pool
+    this.pool = new ResourcePool({ max: 10 });
+  }
+
+  protected async handle(input: Input, context: ToolContext): Promise<Output> {
+    // Acquire resource from pool
+    const resource = await this.pool.acquire();
+    
+    try {
+      return await this.processWithResource(resource, input);
+    } finally {
+      // Always release resource
+      this.pool.release(resource);
+    }
+  }
+
+  protected async cleanup(): Promise<void> {
+    // Drain pool on cleanup
+    await this.pool.drain();
+  }
+}
+```
+
+## Security Best Practices
+
+1. **Always validate input** - Use Zod schemas and additional validation
+2. **Check permissions** - Implement checkPermissions for sensitive operations
+3. **Sanitize paths** - Prevent directory traversal attacks
+4. **Limit resource usage** - Implement timeouts and size limits
+5. **Log security events** - Track permission denials and suspicious activity
+6. **Use prepared statements** - Prevent SQL injection in database tools
+7. **Validate URLs** - Block internal/private IP ranges in HTTP tools
+
+## Debugging Tools
+
+### Logging
+
+```typescript
+protected async handle(input: Input, context: ToolContext): Promise<Output> {
+  this.logger.debug({ input }, 'Processing request');
+  
+  try {
+    const result = await this.process(input);
+    this.logger.info({ result }, 'Request successful');
+    return result;
+  } catch (error) {
+    this.logger.error({ error, input }, 'Request failed');
+    throw error;
+  }
+}
+```
+
+### Metrics
+
+```typescript
+protected async handle(input: Input, context: ToolContext): Promise<Output> {
+  const timer = this.metrics.startTimer('tool_execution_duration', {
+    tool: this.config.name,
+  });
+
+  try {
+    const result = await this.process(input);
+    
+    this.metrics.increment('tool_execution_success', {
+      tool: this.config.name,
+    });
+    
+    return result;
+  } catch (error) {
+    this.metrics.increment('tool_execution_error', {
+      tool: this.config.name,
+      error: error.code,
+    });
+    
+    throw error;
+  } finally {
+    timer.end();
+  }
+}

+# MCP Server Built-in Tools
+
+The MCP server comes with a comprehensive set of built-in tools for common operations. All tools include security features, permission controls, and consistent error handling.
+
+## Available Tools
+
+### 📁 File Operations
+Tools for reading, writing, and listing files with security controls.
+
+- [**FileReadTool**](./file-operations.md#filereadtool) - Read file contents
+- [**FileWriteTool**](./file-operations.md#filewritetool) - Write content to files
+- [**FileListTool**](./file-operations.md#filelisttool) - List directory contents
+
+### 💻 System Operations
+Execute system commands with security restrictions.
+
+- [**SystemCommandTool**](./system-command.md) - Execute whitelisted system commands
+
+### 🌐 Network Operations
+Make HTTP requests to external services.
+
+- [**HttpRequestTool**](./http-request.md) - Make HTTP/HTTPS requests
+
+## Permission Model
+
+Each tool requires specific permissions to execute:
+
+| Tool | Required Permission | Description |
+|------|-------------------|-------------|
+| FileReadTool | `file:read` | Read access to files |
+| FileWriteTool | `file:write` | Write access to files |
+| FileListTool | `file:read` | Read access to directories |
+| SystemCommandTool | `system:exec` | Execute system commands |
+| HttpRequestTool | `network:http` | Make HTTP requests |
+
+## Security Features
+
+All built-in tools implement comprehensive security controls:
+
+### 🛡️ Path Security
+- **Directory traversal prevention** - Blocks `..` and absolute paths outside allowed directories
+- **Restricted directories** - Cannot access system directories like `/etc`, `/sys`, `/proc`
+- **Allowed paths** - Only current working directory and system temp directory
+
+### 🔒 Input Validation
+- **Schema validation** - All inputs validated with Zod schemas
+- **Command whitelisting** - Only safe system commands allowed
+- **Shell injection prevention** - Blocks shell operators in arguments
+- **URL validation** - Validates and blocks private IP ranges
+
+### ⏱️ Resource Limits
+- **Timeouts** - All operations have configurable timeouts
+- **Size limits** - File operations limited to 10MB
+- **Output limits** - Command output limited to 1MB
+
+## Error Handling
+
+All tools follow consistent error handling patterns:
+
+```javascript
+try {
+  const result = await mcp.callTool('tool_name', params);
+  // Handle success
+} catch (error) {
+  // Errors include:
+  // - Permission denied
+  // - Invalid input
+  // - Resource not found
+  // - Timeout exceeded
+  // - Operation failed
+}
+```
+
+## Usage Examples
+
+### Reading a Configuration File
+```javascript
+const config = await mcp.callTool('file_read', {
+  path: './config.json'
+});
+const parsedConfig = JSON.parse(config.content);
+```
+
+### Writing Log Data
+```javascript
+await mcp.callTool('file_write', {
+  path: './logs/app.log',
+  content: `[${new Date().toISOString()}] Application started\n`,
+  mode: 'append'
+});
+```
+
+### Listing Project Files
+```javascript
+const files = await mcp.callTool('file_list', {
+  path: './src',
+  recursive: true,
+  pattern: '*.js'
+});
+```
+
+### Running System Commands
+```javascript
+const result = await mcp.callTool('system_command', {
+  command: 'grep',
+  args: ['-r', 'TODO', '.'],
+  cwd: './src'
+});
+```
+
+### Making API Requests
+```javascript
+const response = await mcp.callTool('http_request', {
+  url: 'https://api.github.com/user',
+  headers: {
+    'Authorization': 'token YOUR_TOKEN'
+  }
+});
+```
+
+## Best Practices
+
+1. **Always handle errors** - Tools can fail for various reasons
+2. **Use appropriate timeouts** - Don't let operations hang
+3. **Validate inputs** - Even though tools validate, check your data
+4. **Check permissions** - Ensure required permissions are granted
+5. **Use relative paths** - More portable than absolute paths
+6. **Respect rate limits** - Especially for HTTP requests
+7. **Log operations** - Track what tools are doing
+
+## Extending with Custom Tools
+
+While built-in tools cover common use cases, you can create custom tools for specific needs. See the [Module Development Guide](../modules/development.md) for details on creating custom tools.
+
+## Tool Lifecycle
+
+1. **Input validation** - Schema validation with Zod
+2. **Permission check** - Verify required permissions
+3. **Pre-execution hooks** - Custom validation/preparation
+4. **Execution** - Actual tool operation
+5. **Output formatting** - Consistent response format
+6. **Error handling** - Structured error responses
+
+## Performance Considerations
+
+- File operations are synchronous within the tool
+- HTTP requests use native fetch API
+- System commands spawn child processes
+- All operations subject to timeout limits
+- Large file operations may impact performance
+
+## Troubleshooting
+
+### Permission Denied
+```
+Error: Permission denied: file:read required
+```
+Ensure the tool has required permissions in the auth context.
+
+### Invalid Path
+```
+Error: Invalid path: directory traversal not allowed
+```
+Use paths within the current directory or temp directory.
+
+### Command Not Allowed
+```
+Error: Command not allowed: rm
+```
+Only whitelisted commands can be executed.
+
+### Timeout Exceeded
+```
+Error: Request timeout after 30000ms
+```
+Increase timeout or optimize the operation.
+
+## Version History
+
+- **v0.1.0** - Initial release with basic file, system, and HTTP tools
+- **v0.2.0** - Added security controls and permission system
+- **v0.3.0** - Enhanced error handling and validation

+# File Operations Tools
+
+The MCP server provides several built-in tools for file system operations with comprehensive security controls.
+
+## FileReadTool
+
+Reads the contents of a file with security restrictions.
+
+### Input Schema
+```typescript
+{
+  path: string;        // File path (relative or absolute)
+  encoding?: 'utf8' | 'binary';  // Default: 'utf8'
+}
+```
+
+### Output Schema
+```typescript
+{
+  content: string;     // File contents
+  size: number;        // File size in bytes
+  path: string;        // Absolute file path
+}
+```
+
+### Security Features
+- Prevents directory traversal attacks
+- Only allows access to files within current working directory or system temp directory
+- File size limit: 10MB
+- Requires `file:read` permission
+
+### Example Usage
+```javascript
+const result = await mcp.callTool('file_read', {
+  path: './config.json',
+  encoding: 'utf8'
+});
+console.log(result.content);
+```
+
+## FileWriteTool
+
+Writes content to a file with security restrictions.
+
+### Input Schema
+```typescript
+{
+  path: string;        // File path (relative or absolute)
+  content: string;     // Content to write
+  encoding?: 'utf8' | 'binary' | 'base64';  // Default: 'utf8'
+  mode?: 'overwrite' | 'append';             // Default: 'overwrite'
+}
+```
+
+### Output Schema
+```typescript
+{
+  path: string;        // Absolute file path
+  size: number;        // File size after write
+  mode: string;        // Write mode used
+}
+```
+
+### Security Features
+- Prevents directory traversal attacks
+- Only allows writing within current working directory or system temp directory
+- Blocks writing to system directories (/etc, /sys, /proc, /dev)
+- Requires `file:write` permission
+- Automatically creates parent directories if needed
+
+### Example Usage
+```javascript
+// Write text file
+await mcp.callTool('file_write', {
+  path: './output.txt',
+  content: 'Hello, World!'
+});
+
+// Write binary file
+await mcp.callTool('file_write', {
+  path: './image.png',
+  content: 'iVBORw0KGgoAAAANS...', // base64 encoded
+  encoding: 'base64'
+});
+
+// Append to file
+await mcp.callTool('file_write', {
+  path: './log.txt',
+  content: 'New log entry\n',
+  mode: 'append'
+});
+```
+
+## FileListTool
+
+Lists files and directories with filtering options.
+
+### Input Schema
+```typescript
+{
+  path: string;              // Directory path
+  recursive?: boolean;       // Recurse into subdirectories
+  pattern?: string;          // Glob pattern filter (e.g., '*.txt')
+  includeHidden?: boolean;   // Include hidden files (starting with .)
+}
+```
+
+### Output Schema
+```typescript
+{
+  path: string;              // Directory path
+  entries: Array<{
+    path: string;            // Full path
+    type: 'file' | 'directory' | 'symlink' | 'other';
+    name: string;            // File/directory name
+    size: number;            // Size in bytes
+    modified: string;        // ISO date string
+  }>;
+  totalSize: number;         // Total size of all files
+}
+```
+
+### Security Features
+- Prevents directory traversal attacks
+- Only allows listing within current working directory or system temp directory
+- Requires `file:read` permission
+- Skips inaccessible items instead of failing
+
+### Example Usage
+```javascript
+// List directory contents
+const result = await mcp.callTool('file_list', {
+  path: './src'
+});
+
+// List recursively with pattern
+const jsFiles = await mcp.callTool('file_list', {
+  path: './src',
+  recursive: true,
+  pattern: '*.js'
+});
+
+// Include hidden files
+const allFiles = await mcp.callTool('file_list', {
+  path: './',
+  includeHidden: true
+});
+```
+
+## Error Handling
+
+All file operation tools follow consistent error handling:
+
+- **File not found**: Returns clear error message with the path
+- **Permission denied**: Returns error when lacking required permissions
+- **Invalid paths**: Blocks directory traversal and system paths
+- **Size limits**: Enforces reasonable limits to prevent abuse
+
+## Best Practices
+
+1. **Always use relative paths** when possible for better portability
+2. **Check permissions** before attempting operations
+3. **Handle errors gracefully** - file operations can fail for many reasons
+4. **Use appropriate encodings** - utf8 for text, base64 for binary data
+5. **Be mindful of file sizes** - large files can impact performance

+# HTTP Request Tool
+
+Make HTTP/HTTPS requests with comprehensive options and security controls.
+
+## Overview
+
+The HttpRequestTool enables making HTTP requests to external services with support for various methods, headers, authentication, and response handling.
+
+## Input Schema
+
+```typescript
+{
+  url: string;                        // Target URL (required)
+  method?: 'GET' | 'POST' | 'PUT' | 'DELETE' | 'PATCH' | 'HEAD' | 'OPTIONS';
+  headers?: Record<string, string>;   // Request headers
+  body?: string | object;             // Request body
+  timeout?: number;                   // Timeout in ms (default: 30000)
+  followRedirects?: boolean;          // Follow redirects (default: true)
+}
+```
+
+## Output Schema
+
+```typescript
+{
+  status: number;                     // HTTP status code
+  statusText: string;                 // Status message
+  headers: Record<string, string>;    // Response headers
+  body: any;                          // Response body (parsed based on content-type)
+  duration: number;                   // Request duration in ms
+}
+```
+
+## Features
+
+### Supported Methods
+- **GET** - Retrieve data
+- **POST** - Submit data
+- **PUT** - Update resource
+- **DELETE** - Remove resource
+- **PATCH** - Partial update
+- **HEAD** - Headers only
+- **OPTIONS** - Check allowed methods
+
+### Automatic Content Handling
+- JSON responses are automatically parsed
+- Text responses returned as strings
+- Binary data returned as base64 encoded strings
+- Content-Type header automatically set for JSON bodies
+
+### Security Features
+- Blocks requests to private IP ranges (localhost, internal networks)
+- Validates URLs before making requests
+- Timeout protection against hanging requests
+- Requires `network:http` permission
+
+## Example Usage
+
+### Simple GET Request
+```javascript
+const response = await mcp.callTool('http_request', {
+  url: 'https://api.example.com/users'
+});
+console.log(response.body); // Parsed JSON
+```
+
+### POST with JSON Body
+```javascript
+const response = await mcp.callTool('http_request', {
+  url: 'https://api.example.com/users',
+  method: 'POST',
+  body: {
+    name: 'John Doe',
+    email: 'john@example.com'
+  }
+});
+```
+
+### Custom Headers
+```javascript
+const response = await mcp.callTool('http_request', {
+  url: 'https://api.example.com/data',
+  headers: {
+    'Authorization': 'Bearer token123',
+    'X-API-Key': 'myapikey'
+  }
+});
+```
+
+### Form Data
+```javascript
+const response = await mcp.callTool('http_request', {
+  url: 'https://api.example.com/form',
+  method: 'POST',
+  headers: {
+    'Content-Type': 'application/x-www-form-urlencoded'
+  },
+  body: 'name=John&email=john@example.com'
+});
+```
+
+### With Timeout
+```javascript
+const response = await mcp.callTool('http_request', {
+  url: 'https://slow-api.example.com/data',
+  timeout: 5000  // 5 seconds
+});
+```
+
+### Disable Redirect Following
+```javascript
+const response = await mcp.callTool('http_request', {
+  url: 'https://example.com/redirect',
+  followRedirects: false
+});
+// Check response.status for 301/302
+```
+
+## Response Handling
+
+### JSON Response
+```javascript
+const response = await mcp.callTool('http_request', {
+  url: 'https://api.example.com/json'
+});
+// response.body is already parsed object
+console.log(response.body.data);
+```
+
+### Text Response
+```javascript
+const response = await mcp.callTool('http_request', {
+  url: 'https://example.com/text.txt'
+});
+// response.body is string
+console.log(response.body);
+```
+
+### Binary Response
+```javascript
+const response = await mcp.callTool('http_request', {
+  url: 'https://example.com/image.png'
+});
+// response.body is base64 encoded string
+const buffer = Buffer.from(response.body, 'base64');
+```
+
+### Status Checking
+```javascript
+const response = await mcp.callTool('http_request', {
+  url: 'https://api.example.com/resource'
+});
+
+if (response.status >= 200 && response.status < 300) {
+  // Success
+} else if (response.status === 404) {
+  // Not found
+} else if (response.status >= 500) {
+  // Server error
+}
+```
+
+## Error Handling
+
+### Network Errors
+```javascript
+try {
+  const response = await mcp.callTool('http_request', {
+    url: 'https://nonexistent.example.com'
+  });
+} catch (error) {
+  // Error: HTTP request failed: ...
+}
+```
+
+### Timeout Errors
+```javascript
+try {
+  const response = await mcp.callTool('http_request', {
+    url: 'https://slow.example.com',
+    timeout: 1000
+  });
+} catch (error) {
+  // Error: Request timeout after 1000ms
+}
+```
+
+### Invalid URLs
+```javascript
+try {
+  const response = await mcp.callTool('http_request', {
+    url: 'not-a-url'
+  });
+} catch (error) {
+  // Error: Invalid URL
+}
+```
+
+### Blocked Internal IPs
+```javascript
+try {
+  const response = await mcp.callTool('http_request', {
+    url: 'http://192.168.1.1/admin'
+  });
+} catch (error) {
+  // Error: Requests to private IP ranges are not allowed
+}
+```
+
+## Best Practices
+
+1. **Always set appropriate timeouts** for external requests
+2. **Handle all status codes** - don't assume 200 OK
+3. **Use HTTPS** when possible for security
+4. **Set User-Agent** header to identify your application
+5. **Implement retry logic** for transient failures
+6. **Respect rate limits** of external APIs
+7. **Validate response data** before using it
+
+## Common Patterns
+
+### API Authentication
+```javascript
+// Bearer Token
+const response = await mcp.callTool('http_request', {
+  url: 'https://api.example.com/protected',
+  headers: {
+    'Authorization': 'Bearer your-token-here'
+  }
+});
+
+// API Key
+const response = await mcp.callTool('http_request', {
+  url: 'https://api.example.com/data',
+  headers: {
+    'X-API-Key': 'your-api-key'
+  }
+});
+
+// Basic Auth
+const credentials = Buffer.from('username:password').toString('base64');
+const response = await mcp.callTool('http_request', {
+  url: 'https://api.example.com/secure',
+  headers: {
+    'Authorization': `Basic ${credentials}`
+  }
+});
+```
+
+### Pagination
+```javascript
+let allData = [];
+let page = 1;
+let hasMore = true;
+
+while (hasMore) {
+  const response = await mcp.callTool('http_request', {
+    url: `https://api.example.com/items?page=${page}&limit=100`
+  });
+  
+  allData = allData.concat(response.body.items);
+  hasMore = response.body.hasNextPage;
+  page++;
+}
+```
+
+## Limitations
+
+- Cannot access localhost or private networks
+- Maximum timeout of 5 minutes
+- No support for streaming responses
+- No built-in retry mechanism
+- No connection pooling or keep-alive

+# System Command Tool
+
+Execute system commands with comprehensive security controls and output handling.
+
+## Overview
+
+The SystemCommandTool allows controlled execution of whitelisted system commands with proper security boundaries, timeout handling, and output management.
+
+## Input Schema
+
+```typescript
+{
+  command: string;           // Command to execute (must be whitelisted)
+  args?: string[];           // Command arguments
+  cwd?: string;              // Working directory
+  env?: Record<string, string>;  // Environment variables
+  timeout?: number;          // Timeout in ms (100-300000, default: 30000)
+  stdin?: string;            // Input to send to stdin
+}
+```
+
+## Output Schema
+
+```typescript
+{
+  stdout: string;            // Standard output
+  stderr: string;            // Standard error output
+  exitCode: number;          // Process exit code
+  duration: number;          // Execution time in ms
+}
+```
+
+## Whitelisted Commands
+
+Only the following commands are allowed for security:
+
+- `ls` - List directory contents
+- `cat` - Display file contents
+- `grep` - Search text patterns
+- `find` - Find files and directories
+- `echo` - Print text
+- `pwd` - Print working directory
+- `whoami` - Show current user
+- `date` - Show current date/time
+- `env` - Show environment variables
+- `which` - Find command location
+- `wc` - Word/line/character count
+- `head` - Show first lines
+- `tail` - Show last lines
+- `sort` - Sort lines
+- `uniq` - Remove duplicate lines
+- `curl` - HTTP requests
+- `ping` - Network connectivity test
+- `dig` - DNS lookup
+- `ps` - Process list
+- `df` - Disk usage
+- `du` - Directory size
+- `uptime` - System uptime
+
+## Security Features
+
+### Command Validation
+- Only whitelisted commands can be executed
+- Shell operators (`|`, `&`, `;`, `>`, `<`, etc.) are blocked in arguments
+- Prevents command injection attacks
+
+### Resource Limits
+- Configurable timeout (max 5 minutes)
+- Output size limited to 1MB per stream
+- Process is killed if limits exceeded
+
+### Permission Control
+- Requires `system:exec` permission
+- Inherits process environment with modifications
+
+## Example Usage
+
+### Basic Command
+```javascript
+const result = await mcp.callTool('system_command', {
+  command: 'ls',
+  args: ['-la', '/tmp']
+});
+console.log(result.stdout);
+```
+
+### With Working Directory
+```javascript
+const result = await mcp.callTool('system_command', {
+  command: 'grep',
+  args: ['-r', 'TODO', '.'],
+  cwd: '/home/user/project'
+});
+```
+
+### With Environment Variables
+```javascript
+const result = await mcp.callTool('system_command', {
+  command: 'echo',
+  args: ['$MY_VAR'],
+  env: {
+    MY_VAR: 'Hello from environment!'
+  }
+});
+```
+
+### With Timeout
+```javascript
+const result = await mcp.callTool('system_command', {
+  command: 'find',
+  args: ['/', '-name', '*.log'],
+  timeout: 5000  // 5 seconds
+});
+```
+
+### With stdin Input
+```javascript
+const result = await mcp.callTool('system_command', {
+  command: 'grep',
+  args: ['error'],
+  stdin: 'line 1\nerror on line 2\nline 3'
+});
+```
+
+## Error Handling
+
+### Command Not Allowed
+```javascript
+// This will throw an error
+await mcp.callTool('system_command', {
+  command: 'rm'  // Not in whitelist
+});
+// Error: Command not allowed: rm
+```
+
+### Shell Injection Prevention
+```javascript
+// This will throw an error
+await mcp.callTool('system_command', {
+  command: 'ls',
+  args: ['; rm -rf /']  // Shell operators blocked
+});
+// Error: Shell characters not allowed in arguments
+```
+
+### Timeout Handling
+```javascript
+try {
+  await mcp.callTool('system_command', {
+    command: 'find',
+    args: ['/'],
+    timeout: 1000  // 1 second
+  });
+} catch (error) {
+  // Error: Command timed out after 1000ms
+}
+```
+
+### Non-Zero Exit Codes
+Non-zero exit codes don't throw errors but are returned in the result:
+```javascript
+const result = await mcp.callTool('system_command', {
+  command: 'grep',
+  args: ['nonexistent', 'file.txt']
+});
+// result.exitCode will be 1 or 2
+// result.stderr will contain the error message
+```
+
+## Best Practices
+
+1. **Use specific commands** instead of shell scripts
+2. **Set appropriate timeouts** for long-running commands
+3. **Check exit codes** to handle command failures
+4. **Limit output size** by using head/tail when appropriate
+5. **Avoid user input** in command arguments without validation
+6. **Use working directory** instead of cd commands
+7. **Monitor stderr** for warnings and errors
+
+## Limitations
+
+- No shell features (pipes, redirects, wildcards)
+- No interactive commands
+- No sudo or privileged operations
+- Output limited to 1MB per stream
+- Maximum timeout of 5 minutes
