WCGW MCP Server

What is WCGW?

WCGW is a macOS-only VS Code extension that allows users to share code snippets and terminal output with contextual information to the Claude desktop application. It is designed to work with the wcgw MCP server and provides automatic detection and attachment to WCGW screen sessions.

How to use WCGW?

After installation, select code in the editor or terminal output, press Cmd+' to send the selection with a custom instruction to Claude, or press Cmd+Shift+' to copy the selection along with broader workspace context (repo structure, frequently relevant files). The extension can automatically poll for matching WCGW screen sessions every 5 seconds and attach to them. Use the commands "WCGW: Check and Attach to Screen Sessions" or "WCGW: Toggle Screen Session Polling" for manual control.
