Vscode Mcp

VSCode MCP is an MCP server that connects external AI agents and assistants directly to Visual Studio Code through the Model Context Protocol. Developed by Block, Inc., the project consists of an MCP server and a companion Visual Studio Code extension. Software engineers, autonomous coding agents, and AI assistants such as Goose and Claude Desktop use this integration to inspect and manipulate codebases within an active editor session. The server enables AI systems to open files, launch project directories, and prepare structured file modifications. Rather than modifying files on disk without user awareness, the server includes dedicated tooling to display visual diffs within the editor interface, allowing developers to inspect proposed code changes and approve or reject them directly inside Visual Studio Code. Additionally, the server exposes status and discovery tools to monitor extension health, verify network communication ports, and enumerate active projects. By bridging language models with the developer's local development environment, VSCode MCP keeps the human programmer in the loop while automating routine editing and navigation workflows.

How to install and configure Vscode Mcp

1. Install the server globally or locally using the command: bash npx vscode-mcp-server install 2. Install the companion MCP Extension in Visual Studio Code from the marketplace. 3. Configure your MCP client. For Claude Desktop, edit your claude_desktop_config.json: json { "mcpServers": { "vscode-mcp-server": { "command": "npx", "args": ["vscode-mcp-server"], "env": {} } } } 4. For Goose Desktop, add an extension with ID code-mcp, name VS Code, and command npx vscode-mcp-server.

What you can do with Vscode Mcp

• Open project directories in Visual Studio Code dynamically when starting a new coding session with an AI agent. - Display interactive code diffs in the editor for existing files so human developers can inspect and approve modifications. - Open newly generated or existing source files inside the active editor window for immediate review during development. - Query active project listings and check the companion extension connection status from an autonomous agent session.
