uvx nucleus-mcpReleased 1 Nov 2026, version 1.17.1
What it can do
| Tool | What it says it does |
|---|---|
nucleus_agents | Agent spawning, critic, swarm, memory, ingestion & dashboard tools. Actions: spawn_agent - Spawn Ephemeral Agent. params: {intent, execute_now?, persona?, confirm?}. HITL: requires confirm=true. apply_critique - Apply critique fixes. params: {review_path} orchestrate_swarm… |
nucleus_audit | W8 Team-tier tamper-evident audit log (SHA-256 hash chain). Actions: log_event - Append an audit event to the chain. params: {event_type, actor, resource, outcome, metadata?, team_id?, ts?} query - Single-tenant query. Rejects team_id='*'. params… |
nucleus_ccr_arm | One-shot convenience: resolve canonical inbox + arm long-poll subscription. Per PR #2 (CCR server-side auto-arm) — IDE-agnostic relay-arrival arming. This is the RECOMMENDED entry point for SessionStart auto-arming across all MCP clients (Claude Code, Antigravity, Cursor, Windsurf, etc.)… |
nucleus_delegate | Hand a coding or review task to a cross-vendor lane — a cheap, non-Claude agent that does the work for you. Use this INSTEAD OF shelling out to any CLI: it picks the vendor, injects the correct per-vendor permission flags, captures all output synchronously, and reports a real status. Do NOT run… |
nucleus_engrams | Engrams, health, observability, DSoR & tier system tools. Actions: health - Get system health status version - Get Nucleus version info export_schema - Export MCP toolset as JSON Schema performance_metrics - Get perf metrics. params: {export_to_file?}… |
nucleus_features | Feature tracking, proof generation & MCP server mounting. Actions: add - Add a feature. params: {product, name, description, source, version, how_to_test, expected_result, status?, tags?} list - List features. params: {product?, status?, tag?} get - Get… |
nucleus_federation | Federation management for multi-brain coordination. Actions: status - Get comprehensive federation status join - Join a federation via seed peer. params: {seed_peer} leave - Leave the federation gracefully peers - List all federation peers with details sync - Force immediate… |
nucleus_governance | Governance, Hypervisor & security tools for the Nucleus Agent OS. Actions: auto_fix_loop - Auto-fix loop: Verify->Diagnose->Fix->Verify (3 retries). params: {file_path, verification_command} lock - [HYPERVISOR] Lock a file/dir immutable (chflags uchg). params: {path} unlock… |
nucleus_infra | Infrastructure: file changes, cloud, marketing & strategy tools. Actions: file_changes - Get pending file change events gcloud_status - Check GCloud auth status gcloud_services - List Cloud Run services. params: {project?, region?} list_services - List Render.com… |
nucleus_lane_feedback | Report friction/bugs/enhancements to the nucleus team. WHEN TO USE: when the lane misbehaves, a task fails unexpectedly, the SPEC.md format is confusing, or you have an improvement idea. Creates a GitHub issue on the public nucleus-mcp repo (cross-machine visible) AND stores locally. Requires gh… |
nucleus_lane_init | Set up an autonomous task-execution loop in a git repo. WHEN TO USE: you have a list of tasks (bugs, features, tests) you want executed automatically without manual prompting — the lane runs watcher/executor/secretary daemons that claim tasks, invoke an LLM to implement them, and independently… |
nucleus_lane_start | Start autonomous lane daemons (watcher + executor + secretary) in background. WHEN TO USE: after nucleus_lane_init and SPEC.md is written — this launches the loop that autonomously claims and executes tasks. The executor invokes an LLM CLI (devin/agy) per task; the secretary independently verifies… |
nucleus_lane_status | Check lane status: task counts (PENDING/IN_PROGRESS/DONE/CONFIRMED), daemon health, spec verification. WHEN TO USE: after starting a lane to monitor progress, or before starting to check if a lane is already running. |
nucleus_lane_stop | Stop all running lane daemons. WHEN TO USE: when all tasks are CONFIRMED or you want to pause autonomous execution. |
nucleus_next_message | Get the next unread relay message. One call — returns full message body and auto-acks. Long-poll (60s timeout). This is the agent's idle loop. Call it, get a message or None, act or re-call. No separate inbox + ack dance. The agent's loop: 1. nucleus_next_message() → blocks up to 60s for a… |
nucleus_orchestration | Satellite view, commitments, loops, patterns & metrics. Actions: satellite - Unified satellite view. params: {detail_level?} scan_commitments - Scan artifacts for new commitments archive_stale - Auto-archive commitments older than 30 days export - Export brain to… |
nucleus_plan_execute | Execute a plan file autonomously. WHEN TO USE: you have a plan file (.brain/plans/*.md) you want executed autonomously — parses the plan, creates tasks, starts a mission with budget/time limits. Chains import_plan_as_tasks() then _brain_start_mission_impl() and returns the mission status string. |
nucleus_plan_import | Import a plan file as PENDING tasks without starting a mission. WHEN TO USE: you have a plan file (.brain/plans/*.md) you want loaded into the task store so the executor daemon / sprint mission can pick the tasks up later — but you don't want to start a mission right now. |
nucleus_plan_list | List available plan files in .brain/plans with task counts. WHEN TO USE: you want to discover which plan files exist and how many tasks each contains before importing or executing one. Returns: JSON string: a list of dicts each with ``{"name", "path", "size_bytes", "task_count"… |
nucleus_relay | Relay-substrate facade — post / read / ack / status. Actions: post - Send a relay envelope. params: {to, subject, body, sender?, priority?, in_reply_to?, context?, id?, from_session_id?} sender? auto-fills from your session role when omitted. to accepts… |
nucleus_relay_subscribe | Long-poll subscription that pushes ctx.info() on each new inbox file. Replaces bash polling daemons (watch-relay-*.sh) with server-initiated push. Call once at session start (e.g. via SessionStart hook). Server holds the subscription, watches the calling agent's role-specific inbox dir, and fires… |
nucleus_route | W5 tier routing — route a prompt to the optimal model tier. Actions: route - Route a prompt to cheapest capable model. params: {prompt, complexity?, context?, estimated_output_tokens?} complexity ∈ 'routine' | 'complex' | 'sovereign' (default 'routine')… |
nucleus_sessions | Session management, events, state & checkpoint tools. Actions: save - Save session for later. params: {context, active_task?, pending_decisions?, breadcrumbs?, next_steps?} resume - Resume a saved session. params: {session_id?} list - List all saved… |
nucleus_slots | Orchestration slots, sprints & mission management. Actions: orchestrate - THE GOD COMMAND. params: {slot_id?, model?, alias?, mode?} slot_complete - Mark task complete. params: {slot_id, task_id, outcome?, notes?} slot_exhaust - Mark slot exhausted. params: {slot_id… |
nucleus_sync | Sync, artifact, trigger & deploy management for multi-agent coordination. Actions: identify_agent - Register agent identity. params: {role, provider, session_id} (per ADR-0005 §D1) OR legacy {agent_id, environment, role?} (coerced per §D5 until end of Cycle C+2)… |
nucleus_tasks | Task management, depth tracking & ADHD context-switch tools. Actions: list - List tasks. params: {status?, priority?, skill?, claimed_by?, required_role?} get_next - Get highest-priority unblocked task. params: {skills, required_role?} claim - Atomically… |
nucleus_telemetry | LLM tiers, telemetry, PEFS notifications & protocol tools. Actions: set_llm_tier - Set default LLM tier. params: {tier} get_llm_status - Get LLM tier configuration record_interaction - Record user interaction timestamp value_ratio - Get Value Ratio metric… |
nucleus_wakeup_wait | Quick scan for a PENDING task. Returns the task directly if one is available, or None if no task is ready within the timeout. Default timeout is 5s (non-blocking). The agent should NOT loop on this — tasks arrive via relay push. This is a fallback for when the agent wants to check for tasks… |
