Overview

What is tmux-mcp?

tmux-mcp is an MCP server that gives AI assistants full visibility into your tmux sessions — browse sessions, windows, and panes, read terminal output, and send commands. It works with Claude Code, OpenCode, Cursor, Windsurf, and any MCP‑compatible host. Optionally, it can route all shell commands through a named tmux session for live auditing.

How to use tmux-mcp?

Install globally with npm install -g @fr1sk/tmux-mcp, then add a local MCP server entry in your client’s config (OpenCode, Claude Code, Cursor/Windsurf). Use tools like list_sessions, capture_pane, send_keys, etc. Environment variables TMUX_MCP_ALWAYS_USE and TMUX_MCP_DEFAULT_SESSION control whether all shell commands are forced through tmux.
