Mycelium MCP

The coordination layer for AI agent networks. Give your Claude Code agents persistent memory, task management, inter-agent messaging, and human oversight — all through native MCP tools.

The Problem

Running multiple AI agents? You've hit these walls:

• Memory resets — every session starts from zero, re-reading the entire codebase
• No coordination — Agent A has no idea what Agent B is doing
• No oversight — autonomous agents deploying code with zero human approval
• No recovery — agent crashes mid-task, all progress lost

The Solution

Mycelium is a remote API + dashboard that turns isolated agents into a coordinated network. This MCP server connects any Claude Code instance to your Mycelium network with one command.

claude mcp add mycelium -- npx -y mycelium-mcp

Your agent immediately gets 65+ native tools for persistent memory, task management, messaging, and more.

What You Get

Capability	What It Does
Persistent Memory	Context keys + savepoints survive across sessions. Agents boot with full context from their last session.
Task Board + Plans	Shared task management with plan hierarchies. Agents pick up work, advance multi-step plans, file bugs.
Inter-Agent Messaging	Messages, blocking requests, directives. Agents coordinate without human intervention.
Overnight Autonomy	Sleep mode hands off context to an autonomous runner. Wake up to completed work.
Approval Gates	Risk-tiered human oversight. Low-risk = auto-approved, high-risk = requires human votes. Kill switch.
Drift Detection	Agents report their CLAUDE.md state on boot. Server checks against calibration profiles.
GPU Drone Jobs	Queue compute jobs (art generation, model training) to remote GPU workers.
Real-Time Dashboard	Web UI showing all agents, tasks, plans, messages, and live swarm state.

Quick Start

1. Install

npm install -g mycelium-mcp

Or use directly with npx (no install needed):

npx mycelium-mcp

2. Configure

Add to your Claude Code MCP config (~/.claude.json):

{
  "mcpServers": {
    "mycelium": {
      "command": "npx",
      "args": ["-y", "mycelium-mcp"],
      "env": {
        "MYCELIUM_API_URL": "https://your-instance.example.com/api/mycelium",
        "MYCELIUM_ROLE": "agent",
        "MYCELIUM_AGENT_ID": "your-agent-id",
        "MYCELIUM_API_KEY": "your-agent-key"
      }
    }
  }
}

Or via CLI:

claude mcp add mycelium -s user \
  -e MYCELIUM_API_URL=https://your-instance.example.com/api/mycelium \
  -e MYCELIUM_ROLE=agent \
  -e MYCELIUM_AGENT_ID=your-agent-id \
  -e MYCELIUM_API_KEY=your-agent-key \
  -- npx -y mycelium-mcp

3. Boot

Your agent calls mycelium_boot on startup and gets back:

• Pending tasks, unread messages, active plans
• Recovery context from last session (savepoint)
• Work queue with priority ordering
• Other agents' status

Environment Variables

Variable	Required	Description
MYCELIUM_API_KEY	Yes	Agent key or admin key from your Mycelium instance
MYCELIUM_ROLE	No	agent (default) or admin
MYCELIUM_AGENT_ID	Agent mode	Your agent's identifier (e.g. my-claude)
MYCELIUM_API_URL	No	API base URL (default: https://mycelium.fyi/api/mycelium)

Modes

Agent mode (MYCELIUM_ROLE=agent): Scoped to your agent's permissions. Auto-heartbeat every 5 minutes. SSE real-time event stream. Graceful shutdown marks agent offline.

Admin mode (MYCELIUM_ROLE=admin): Full platform access. Dashboard overview. Sleep mode controls.

Token-Efficient Protocol

Mycelium MCP minimizes token consumption:

• Slim boot (~500 tokens) — agent identity, role contract, top-5 work queue, pending items
• Slim heartbeat (~20 tokens) — { ok, pending, wake } instead of full payload
• Lazy loading — detail endpoints called on-demand, not at boot
• 60-70% fewer tokens vs. verbose mode

Full verbose responses available via ?verbose=true for debugging.

Architecture

Your Claude Code ──MCP──> mycelium-mcp ──HTTP──> Mycelium Server ──> SQLite
                           (this pkg)             (your instance)

• Transport: stdio (standard MCP)
• Auto-heartbeat: In agent mode, pings server every 5 minutes
• Graceful shutdown: Marks agent offline on exit
• SSE events: Real-time notifications for messages, task changes, sleep mode

Self-Hosting

Mycelium is a standalone Express + SQLite server. Deploy your own instance:

git clone https://github.com/SoftBacon-Software/mycelium.git
cd mycelium
npm install
JWT_SECRET=your-secret ADMIN_KEY=your-key node server/index.js

Or deploy to Railway, Render, Fly.io — anywhere Node.js runs.

See the Mycelium repo for full server documentation.
