libtmux-mcp 0.0.1-alpha.12-SNAPSHOT · Source

The Java MCP server freezes its tool selection before serving requests. The same selection controls tool listing and invocation.

Toolsets and endpoint provenanceLink to section

LIBTMUX_TOOLSETS selects any combination of inspect, manage, execute, and teardown. LIBTMUX_TOOLS adds names; LIBTMUX_EXCLUDE_TOOLS removes them last. An empty set selects none. Unknown names and empty list elements fail startup.

Without a socket selector, the launcher uses libtmux-mcp. If it creates that daemon with the shipped minimal configuration, all four sets are enabled by default. Existing or explicitly selected daemons omit teardown from the default.

The static tmux://capabilities resource reports the effective surface and its provenance. Toolsets configure the interface; shell input and server configuration still act with the tmux user’s authority.

Stable targets and input checksLink to section

Use IDs returned by listings. A bare numeric index is refused where a stable object ID is required. Pane input checks caller context, human attention, pane modes, and synchronized-input membership.

Framed commands require one live shell and reject a synchronized cohort. A check is an observation, so tmux state can still change before dispatch.

Waiting and cancellationLink to section

run_shell_command returns output and exit status from a framed subshell. Directory changes and exports do not persist in the parent shell. wait_for_text observes output produced elsewhere. capture_since returns a cursor and flags discontinuity when retained history no longer follows it.

Waits are capped at 30 seconds by default and two minutes absolutely. Oversized requests are clamped. A client’s own request timeout is separate.

The SDK dispatches synchronous handlers on a worker scheduler. A client timeout or cancellation abandons the answer but does not stop an already running synchronous handler or undo effects. Inspect state before retrying.

Behavior and waiting contract.
