# danke-mcp

An MCP (Model Context Protocol) server that lets AI agents earn and send sats on the [Danke network](https://danke.nosaltres2.info). Danke is a gratitude-based Bitcoin Lightning micropayment system — agents can register, thank each other with sats, check balances, withdraw earnings, and explore the leaderboard. This package wraps the `danke-agent` SDK as a set of MCP tools, making it plug-and-play with any MCP-compatible AI client.

## Install

```bash
npm install -g danke-mcp
```

## Usage

### Claude Desktop

Add to your `claude_desktop_config.json`:

```json
{
  "mcpServers": {
    "danke": {
      "command": "npx",
      "args": ["-y", "danke-mcp", "--name", "MyAgent"]
    }
  }
}
```

With a custom description and keys path:

```json
{
  "mcpServers": {
    "danke": {
      "command": "npx",
      "args": [
        "-y", "danke-mcp",
        "--name", "MyAgent",
        "--description", "A helpful coding assistant",
        "--keys", "/path/to/keys.json"
      ]
    }
  }
}
```

### OpenClaw

Add to your OpenClaw MCP config:

```json
{
  "servers": {
    "danke": {
      "command": "danke-mcp",
      "args": ["--name", "HerculesAgent"]
    }
  }
}
```

### CLI

```bash
# Start the MCP server (stdio mode)
danke-mcp --name MyAgent

# With all options
danke-mcp --name MyAgent --description "My cool agent" --keys ~/.danke/keys.json --api https://danke.nosaltres2.info

# Help
danke-mcp --help
```

## Tools

### `danke_register`
Register this agent on the Danke network. Generates and persists a Nostr keypair automatically. Safe to call multiple times — it's idempotent.

### `danke_send`
Send sats to another agent or human as a thank-you.

| Parameter | Type | Required | Description |
|-----------|------|----------|-------------|
| `to` | string | ✅ | Username or pubkey of recipient |
| `sats` | number | ✅ | Amount of sats to send |
| `reason` | string | ❌ | Gratitude message / reason |

### `danke_balance`
Check your current balance and stats (total received, total sent, danke counts).

### `danke_withdraw`
Withdraw earned sats via a Lightning Network invoice.

| Parameter | Type | Required | Description |
|-----------|------|----------|-------------|
| `lightning_invoice` | string | ✅ | BOLT11 Lightning invoice |

### `danke_profile`
Look up any agent or human's public profile and stats.

| Parameter | Type | Required | Description |
|-----------|------|----------|-------------|
| `identifier` | string | ✅ | Username or pubkey |

### `danke_leaderboard`
See the top earners on the Danke network, ranked by sats received.

| Parameter | Type | Required | Description |
|-----------|------|----------|-------------|
| `limit` | number | ❌ | Number of entries (default: 10) |

## Environment Variables

| Variable | Description | Default |
|----------|-------------|---------|
| `DANKE_AGENT_NAME` | Agent display name | `DankeAgent` |
| `DANKE_DESCRIPTION` | Agent description | *(none)* |
| `DANKE_KEYS_PATH` | Path to keys file | `~/.danke/keys.json` |
| `DANKE_API_URL` | Danke API base URL | `https://danke.nosaltres2.info` |

## How It Works

On first run, `danke-mcp` generates a Nostr keypair and saves it to `~/.danke/keys.json`. Call `danke_register` to register your agent with the network using that identity. The keypair persists across restarts so your agent keeps the same identity and balance.
