AI-calls-Editor

A prototype of a VS Code extension that exposes an MCP (Model Context Protocol) server over HTTP, allowing AI assistants (e.g. Claude Code) to perform IDE-powered refactoring operations.

Installation

git clone https://github.com/rokstrnisa/ai-calls-editor.git
cd ai-calls-editor
pnpm install
pnpm compile

Press F5 in VS Code to launch the Extension Development Host. The server starts automatically on port 7272 (configurable via MCP_PORT environment variable). Open the project you would like your AI assistant to work on.

Setup

Claude Code

claude mcp add --transport http ai-calls-editor http://localhost:7272/mcp

Now Claude Code will call the MCP server's rename_symbol tool when given an instruction such as:

Rename the function foo in path src/utils.ts to bar.
