Which coding agents can use expect?

expect works in any agent that reads an MCP config file: Claude Code, Codex, Cursor, Gemini CLI, GitHub Copilot, OpenCode and Windsurf. Each agent reads it from its own file; this page names the file for each one.

How do I add expect to Claude Code?

Run this in your terminal: claude mcp add expect -- npx -y expect-cli@latest mcp
