> Choose callable tools, interpret bounded results, and understand pane observation and cancellation.

The server selects one tmux endpoint and freezes its offered tools at startup.
Read `tmux://capabilities` to inspect that endpoint's provenance and the
effective tool selection.

## Select tools

[Tool selection](https://libtmux.org/en/csharp/latest/mcp/topics/tool-selection/) explains the four groups, exact-name
inclusions, exclusions, and the difference between an unset and an empty
selection. A socket limits the tmux objects the process addresses; it does
not restrict the operating-system authority of commands running in panes.

## Observe a command

[Waits and captured output](https://libtmux.org/en/csharp/latest/mcp/topics/waits-and-output/) distinguishes command
completion from terminal text changes. It covers `run_shell_command`,
`wait_for_text`, incremental captures, response budgets, and cancellation.
An expired wait can leave a command running.

## Resources and prompts

The [capability resource](https://libtmux.org/en/csharp/latest/mcp/topics/tool-selection/#inspect-the-connection) reports
startup configuration. Read live hierarchy and terminal state through tools.
The server offers no workflow prompts or dynamic resource templates.
