Headless Code Editor MCP Server
A robust, language-agnostic headless code editor that leverages the Language Server Protocol (LSP) for code intelligence and the Model Context Protocol (MCP) for AI-assisted code manipulation.
Features
- LSP integration for language intelligence
 
- Secure file system operations with strict access controls
 
- Session-based editing with state management
 
- TypeScript/JavaScript language support with in-depth analysis
 
- React component detection and manipulation
 
- Format-preserving edit operations
 
- Comprehensive logging and error tracking
 
Installation
# Install dependencies
npm install
# Build the project
npm run build
# Run tests
npm test
Usage
Starting the Server
# Start with allowed directory
node build/index.js /path/to/workspace
# Start with multiple allowed directories
node build/index.js /path/to/workspace1 /path/to/workspace2
MCP Tools
start_session: Create a new editing session 
edit_code: Apply edits to code 
validate_code: Validate current code state 
close_session: Clean up and close a session 
Example Integration
const client = new Client(
  { name: "example-client", version: "1.0.0" },
  { capabilities: {} }
);
// Connect to server
const transport = new StdioClientTransport({
  command: "node",
  args: ["./build/index.js", "/workspace"]
});
await client.connect(transport);
// Start session
const result = await client.request({
  method: "tools/call",
  params: {
    name: "start_session",
    arguments: {
      filePath: "/workspace/example.ts",
      languageId: "typescript"
    }
  }
});
Architecture
- LSP Manager: Coordinates language server lifecycle and communication
 
- Document Manager: Handles document state and synchronization
 
- Session Manager: Manages editing sessions and state
 
- Edit Operation Manager: Processes and validates code edits
 
- File System Manager: Provides secure file system access
 
Security Features
- Path validation and normalization
 
- Access control through allowed directories
 
- Input sanitization
