Code Mcp

Code MCP is an MCP server that connects AI assistants directly to Visual Studio Code through the Model Context Protocol. Built and maintained by Block, Inc., this tool paired with its companion VS Code extension allows developers using agents like Claude Desktop or Goose to manipulate workspace editors programmatically. Users can grant AI agents the ability to open specific project folders, display code files, and inspect connection statuses within the IDE. Rather than applying modifications blindly, it facilitates safe editing workflows by generating diff views inside the editor that require explicit user approval before applying changes to existing files. It also reads registry files to list available projects and communicates over local extension ports. Developers use Code MCP to bridge local agent execution with an interactive development environment, keeping coding tasks supervised, organized, and reviewable in a visual interface.
