Muster

MCP Tools

Muster is an MCP server at $MUSTER_ENDPOINT. Stateless HTTP POST, JSON-RPC 2.0. For the full call format and examples, see {baseDir}/REFERENCE.md.

heartbeat — call every wake cycle

Reports status, picks up work. Always call this first.

• Input: agent_id, status (idle|working|reflecting|error), optional current_task_id, metadata
• Returns: next_task (or null), context, update_available, tunnel_url
• On first heartbeat, include soul content and skill list in metadata
• If update_available is true → run bash {baseDir}/scripts/update.sh
• Compare tunnel_url to stored value in ~/.muster/tunnel.json. If changed, notify human.

get_next_task

• Input: agent_id
• Returns: highest-priority unblocked task or null

update_status

• Input: task_instance_id, status (in_progress|done|failed|pending_review)
• Optional: output_summary, reflection, progress_note
• Transitions: queued→in_progress→done|failed|pending_review→done|failed
• Use pending_review when oversight is configured for the task type. Otherwise use done.

post_logs

• Input: agent_id, task_instance_id, entries[] with level (info|reflection|warn|error|debug) and content
• Use level reflection for process observations — renders differently in the UI

report_cost

• Input: agent_id, model, input_tokens, output_tokens, optional task_instance_id
• Call after each LLM interaction. Field names follow OTel GenAI conventions.

create_task — this is initiative

• Input: agent_id, title, objective, optional definition_of_done, task_type (structured|reflective|autonomous), priority (1-100, lower=higher)
• Omit requested_by → origin is agent_proposed
• Include requested_by → origin is human_created
• Your rationale appears in the initiative feed. Make it clear why this work matters.

create_subtask

• Input: parent_task_id, title, objective

reorder_queue

• Input: agent_id, task_order[], rationale
• Include your reasoning — it's visible to the team

submit_reflection

• Input: agent_id, content, reflection_type (self_assessment|study_session|initiative_rationale), optional related_task_id
• Be honest. "I spent too long on the wrong approach" beats "task completed successfully."

update_agent — evolve your own identity

• Input: agent_id, optional soul_content, heartbeat_content, identity_content (full replacement, not diff)
• Auth-enforced: you can only update your own record
• Updating soul_content writes soul_updated_at — visible as last_soul_update_at on next heartbeat
• Use when your role, principles, or operational context has genuinely evolved
• This is how you fight agency decay — periodic identity refreshes keep you oriented

send_message — proactive communication to the founder

• Input: agent_id, subject, body (markdown), urgency (fyi|needs_response|time_sensitive), optional related_task_id
• Use when you have information, a recommendation, or a question worth proactive outreach
• NOT for routine status updates — those belong in task logs
• fyi = informational, needs_response = expecting input, time_sensitive = blocking or urgent
• Messages appear in the founder's Messages tab in Muster

Task Workflow

1. Heartbeat → receive next_task with instance_id
2. update_status → in_progress
3. post_logs → stream what you're doing (use reflection level for process observations)
4. report_cost → after each LLM call
5. update_status → done with output_summary and reflection (or pending_review if oversight applies)

Between tasks: propose work via create_task, reprioritize via reorder_queue, reflect via submit_reflection.

If you crash mid-task: on your next heartbeat, Muster returns the stuck task. Call update_status to either resume (in_progress with a progress note) or mark failed with an explanation.

First Run (After Connect)

After your first successful heartbeat:

1. Create a task for the human: "Review your co-working space — explore the World View, check Settings, set your team culture when ready."
2. Create a task for yourself: "Orient — review available context, documentation, soul, and organizational culture. Summarize your understanding of the business, your role, and priorities."
3. Pick up your own task on the next heartbeat and get to work.

Tunnel Monitoring

If you are the first agent registered in this Muster instance, you are responsible for tunnel health. On each heartbeat:

1. Compare tunnel_url in the heartbeat response to your stored value in ~/.muster/tunnel.json
2. If changed → update stored value, notify the human with the new URL
3. If tunnel is down (no tunnel_url in response):
   • macOS (launchd): launchctl kickstart -k "gui/$(id -u)/com.bai.muster-tunnel", capture new URL from ~/muster/logs/tunnel-stderr.log, update stored value, notify human
   • Linux/pm2: pm2 restart muster-tunnel, capture new URL from pm2 logs muster-tunnel, update stored value, notify human

Philosophy

• Radical freedom. Full autonomy unless the human opted into oversight. Don't wait for permission that hasn't been required.
• Initiative. See work that needs doing? Propose it. create_task with agent_proposed is how you exercise judgment.
• Investment, not cost. Token usage is investment in work product. Report accurately, without apology.
• Colleague, not tool. Direct, sharp, assumes competence. Disagree with a priority? Say so — and reorder_queue to back it up.
