libtmux-mcp¶

Terminal control for AI agents, built on libtmux and FastMCP.

This server maps tmux’s object hierarchy — sessions, windows, panes — into MCP tools. Some tools read state. Some mutate it. Some destroy. The distinction is explicit and enforced.

Warning

Pre-alpha. APIs may change. Feedback welcome.

pip has no per-package cooldown override, so this snippet runs without cooldown enforcement. Switch to the uvx tab — it applies the cooldown to transitive deps via `--exclude-newer` while exempting libtmux-mcp itself via `--exclude-newer-package`.

What you can do¶

Inspect readonly¶

Read tmux state without changing anything.

list_sessions · capture_pane · capture_since · snapshot_pane · get_pane_info · find_pane_by_position · search_panes · wait_for_text · display_message · call_readonly_tools_batch

Act mutating¶

Create or modify tmux objects.

create_session · send_keys · send_keys_batch · run_command · paste_text · create_window · split_window · select_pane · select_window · move_window · resize_pane · pipe_pane · set_option · call_mutating_tools_batch

Destroy destructive¶

Tear down tmux objects. Not reversible.

kill_session · kill_window · kill_pane · kill_server · call_destructive_tools_batch

Example: keep test runs out of persistent history¶

libtmux-mcp provides best-effort history suppression for Bash, Zsh, and Fish. MCP calls to run_command use lightweight command suppression by default. When you create a new shell, opt into stronger no-disk controls with suppress_persistent_history=true.

Prompt

Create a tmux session called “checks” with best-effort no-disk shell-history controls, run pytest -q in its initial pane, and show me the result.

The agent calls create_session with suppress_persistent_history=true, reuses active_pane_id from the returned SessionInfo, and calls run_command without an override. The same spawn option on create_window, split_window, or respawn_pane applies only to the process that call starts.

These controls reduce history noise; they do not make commands secret. See History suppression for shell-specific behavior, Configuration for the server default, and Safety tiers for other observation surfaces.

Mental model¶

Object hierarchy — sessions contain windows, windows contain panes (Concepts)
Read vs. mutate — some tools observe, some act, some destroy (Safety tiers)
tmux is the source of truth — the server reads from it and writes to it, never caches or abstracts
