Click on "Deploy Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type
@followed by the MCP server name and your instructions, e.g., "@Clanker run /clanker:codex to fix the failing tests"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
Clanker
Claude Code plugin + stdio MCP server for running external coding agents as Claude-owned background tasks.
Clanker exposes these slash commands:
Command | Backend |
| Codex ACP |
| Grok ACP |
| Opencode with GLM |
| Opencode with DeepSeek |
| Opencode with Kimi |
| Opencode free model |
| Advanced Opencode model override |
Default mode is background: the Claude Agent task owns the visible bottom task row, while the MCP server owns the ACP backend process. Use --wait to run foreground.

Available Tools
7 toolsclanker_cancelCancel a Clanker's in-flight turnADestructiveIdempotent
Send ACP session/cancel to the Clanker backend. Returns {id, status}. No-op if the session is idle.
Inputs: id (required).
clanker_dispatchDispatch to a Clanker and block until the turn completesADestructive
Convenience path = clanker_dispatch_start + loop clanker_wait until the turn is terminal. Returns the terminal WaitResult {status, final_message, touched_files, plan_final}. For long tasks prefer clanker_dispatch_start + clanker_wait so the caller controls polling and avoids MCP request timeouts.
Inputs: lane (required), prompt (required), cwd, model, +3 more.
clanker_dispatch_startStart a Clanker turn (non-blocking)ADestructive
Spawn/handshake a Clanker and start a prompt turn, returning {id} immediately. Poll progress with clanker_wait(id). Setup errors (unknown backend, worktree creation) fail here; runtime errors surface via clanker_wait.
Inputs: lane (required), prompt (required), cwd, model, +3 more.
clanker_listList active Clanker sessionsARead-onlyIdempotent
Overview of live Clankers: [{id, lane, state (working|idle|stalled), idle_ms, turns_count, plan_summary, suspected_stall}]. Reaped/closed sessions are omitted.
Inputs: no named parameters.
clanker_promptContinue an existing Clanker session with a new turnADestructive
Start a new prompt turn on an already-open session (persistent-session reuse). Returns {id}; poll with clanker_wait(id). Errors if the session was reaped/closed or a turn is already running.
Inputs: id (required), prompt (required).
clanker_statusCheap status of a Clanker runARead-onlyIdempotent
Return {status, plan (checkbox counts + current step), tool_calls, last_event_age_ms, suspected_stall}. Does not wait. suspected_stall flags a running turn silent past the stall threshold.
Inputs: id (required).
clanker_waitLong-poll a Clanker runARead-only
Wait up to timeout_ms (default 30000, cap 55000) for new events or completion. Returns {status, digest, plan_summary, last_event_age_ms, suspected_stall}; when status is terminal also {final_message, touched_files, plan_final}. digest is a human-readable summary of events since the previous wait — tool titles, file writes, plan check changes, key message sentences. Quiet mode (default on): only wakes before the deadline on a plan/status change, a tool error, a suspected stall, or a terminal state — trivial chatter (a tool_call starting, a file-location echo, a message-chunk fragment) does not cut the wait short, so callers no longer need to repoll tightly just because the run is reading/grepping. Pass quiet:false for the old any-event wake-up.
Inputs: id (required), quiet, timeout_ms.

TDQS
A4.4/5.0
Scored across 7 tools
Disambiguation5/5
Each tool has a clearly distinct purpose: cancel, dispatch (convenience wrapper), dispatch_start (initiate), list, prompt (existing session), status, wait. No overlap despite some convenience aliasing.
Naming Consistency5/5
All tool names follow the consistent 'clanker_verb' pattern in snake_case. Verbs are descriptive and predictably relate to actions (cancel, dispatch, list, prompt, status, wait).
Tool Count5/5
7 tools cover the full session management lifecycle without being excessive. Each tool addresses a necessary operation, from starting to polling to cancellation.
Completeness4/5
Core CRUD-like operations are covered: start a turn, wait, check status, list sessions, cancel. Missing an explicit 'delete or close session' tool, but cancel may suffice. Slight gap for cleanup.
