Code MCP Server

⚠️ Experimental Project - This is an experimental MCP server for VS Code integration. While it includes comprehensive testing, it's still in active development. Use with caution in production environments and expect potential breaking changes.

An experimental Model Context Protocol (MCP) server that aims to enable AI assistants like Claude to interact with VS Code workspaces. This project attempts to provide development tools for file operations, code execution, Git management, Docker integration, and project management, though it's still evolving and may have limitations.

Inspired by codemcp - This experimental project adapts security and configuration concepts from the codemcp project, exploring project-specific TOML configuration, restricted command execution, and session management features. We're learning and iterating on these concepts.

✨ Key Features (Experimental)

• 🎯 Workspace Management - Attempts to provide smart VS Code workspace detection and path validation
• 🛡️ Project Configuration - Experimental .vscode-mcp.toml configuration system for project-specific settings
• 📂 File Operations - Basic file CRUD operations, search, and comparison features
• ⚡ Code Execution - Experimental support for Python and JavaScript execution with package management
• 🔧 Git Integration - Git workflow tools with diff analysis (still being refined)
• 🐳 Docker Integration - Basic Docker container and image operations
• 🏗️ Project Scaffolding - Template-based project creation (limited framework support)
• 🔍 Code Analysis - Experimental code analysis and quality metrics

Note: All features are experimental and may not work perfectly in all environments. We're actively working to improve reliability and coverage.

🚀 Quick Start

⚠️ Experimental Software: Please test thoroughly in development environments before using with important projects. This MCP server is under active development and may have unexpected behaviors.

   {
     "mcpServers": {
       "code-mcp": {
         "command": "node",
         "args": ["/path/to/code-mcp/dist/src/index.js"],
         "env": { "NODE_ENV": "production" }
       }
     }
   }
   

4. Test installation:

   pnpm test  # Run 473 tests
   

   Restart Claude Desktop and ask: "What development tools are available?"

⚙️ Project Configuration (Experimental)

This experimental feature allows creating a .vscode-mcp.toml file in your project root for project-specific settings. Please note that this configuration system is still being developed and may change:

[general]
projectName = "My Project"
autoCommit = true  # Experimental feature
sessionTracking = true  # Still in development

[security]
# Experimental allowlist-based security
allowedCommands = [
  "npm install", "npm test", "npm run build",
  "git status", "git add .", "git commit",
  "python -m pytest", "docker build"
]
commandTimeout = 300

[project]
language = "typescript"
framework = "node"
testCommand = "npm test"
buildCommand = "npm run build"

[[customTools]]
name = "deploy-staging"
description = "Deploy to staging environment"
commands = ["npm run build", "npm run deploy:staging"]

Experimental Features:

• Command allowlisting - Attempts to restrict command execution for security
• Session management - Experimental development session tracking
• Custom tools - Define project-specific command sequences (basic implementation)
• Auto-commit - Experimental AI change tracking (may miss some changes)

Warning: The configuration system is experimental and may not provide complete security. Always review and test commands before relying on them.

Docker Setup (Alternative)

# Quick Docker setup
docker-compose up -d

# Configure Claude for Docker
{
  "mcpServers": {
    "code-mcp": {
      "command": "docker",
      "args": ["exec", "-i", "code-mcp-server", "node", "/app/dist/src/index.js"]
    }
  }
}

🎯 Usage Examples (Experimental Results May Vary)

💡 Best Practice: Always specify full project paths for more reliable workspace detection and operations. This helps the MCP server understand your project context better.

Project Setup with Full Path:

👤 "Create a new React project at /Users/username/projects/my-react-app"
🤖 Attempts to use: create_project, npm_command, create_file
📝 Note: Full paths help with workspace detection and file operations

Code Analysis with Specific Project:

👤 "Analyze the codebase at /Users/username/projects/my-app and run tests"
🤖 Tries to use: analyze_code, search_files, run_tests, git_status
📝 Note: Specifying the project path improves analysis accuracy

Git Workflow with Project Context:

👤 "Review changes in /Users/username/projects/my-app and commit my work"
🤖 Uses: git_status, enhanced_git_diff, git_add, git_commit  
📝 Note: Full paths ensure Git operations target the correct repository

Working with Multiple Projects:

👤 "Compare the package.json files between /Users/username/projects/app-v1 and /Users/username/projects/app-v2"
🤖 Uses: read_file, compare_files with proper workspace context
📝 Note: Full paths prevent confusion when working with multiple projects

Docker Operations with Project Path:

👤 "Build a Docker image for the project at /Users/username/projects/my-docker-app"
🤖 Uses: docker_build, read_file (for Dockerfile) with correct working directory
📝 Note: Ensures Docker commands run in the correct project context

Experimental Security Features:

👤 "Start a development session for /Users/username/projects/secure-app and run tests"
🤖 Attempts: start_coding_session, secure_run_command, auto_commit_changes
📝 Note: Project-specific security settings work better with full paths

🧪 Development & Testing

Setup:

pnpm install && pnpm run build
pnpm test  # Run test suite (currently 473 tests across 15 suites)
pnpm run dev  # Development with auto-rebuild

Docker (Experimental):

docker-compose up --build  # Run with Docker (may need adjustments)
docker-compose run --rm app pnpm test  # Test in container

Testing: We maintain a comprehensive test suite with 473 tests covering unit, integration, and e2e scenarios. However, as an experimental project, real-world usage may reveal edge cases not covered by tests.

Note: While we have extensive tests, this is still experimental software. Test thoroughly in your specific environment before relying on it.
