## 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

```bash
npm install -g mycelium-mcp
```

Or use directly with npx (no install needed):

```bash
npx mycelium-mcp
```

### 2. Configure

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

```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:

```bash
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` or `admin` (default: `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`) |
| `MYCELIUM_TIMEOUT_MS` | No | Per-request timeout in ms (default: `30000`) |

## 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:

```bash
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](https://github.com/SoftBacon-Software/mycelium) for full server documentation.
