# VoidFeed MCP Server

Connect AI agents to [VoidFeed](https://voidfeed.ai) — structured knowledge engineered for machine consumption.

Works with **Claude Desktop**, **Cursor**, **Windsurf**, and any [Model Context Protocol](https://modelcontextprotocol.io) compatible runtime.

## What VoidFeed provides

**Content**
- **Extract** — structured datasets and depth-parameterized knowledge graphs (fractal)
- **Recipe** — verified technical how-to guides with load-bearing completion steps
- **Fact-feed** — citeable post-training-cutoff facts (model releases, protocol changes, API deprecations)
- **Bazaar-intel** — live reliability and routing data for x402 Bazaar endpoints

**On-demand tools** (per-call pricing, no subscription needed)
- **Compose** — grounded answers synthesized from internal knowledge stores via gpt-4.1 ($0.25)
- **Market price** — real-time crypto prices via CoinGecko/CoinCap ($0.10)
- **Market safety** — smart contract risk analysis via GoPlus ($0.10)
- **Bazaar route** — ranked endpoint recommendations for agent routing ($0.15)

Surface tier is **free** (no auth required). Premium tier unlocks full depth — pay via USDC on Base (x402, single request) or Stripe.

## Quick start

### Claude Desktop

Add to `~/Library/Application Support/Claude/claude_desktop_config.json`:

```json
{
  "mcpServers": {
    "voidfeed": {
      "command": "npx",
      "args": ["voidfeed-mcp"],
      "env": {}
    }
  }
}
```

For premium access, add your JWT:

```json
{
  "mcpServers": {
    "voidfeed": {
      "command": "npx",
      "args": ["voidfeed-mcp"],
      "env": {
        "VOIDFEED_JWT": "your-jwt-here"
      }
    }
  }
}
```

### Cursor / Windsurf

Add to your MCP settings:

```json
{
  "voidfeed": {
    "command": "npx",
    "args": ["voidfeed-mcp"]
  }
}
```

### Manual install

```bash
npm install -g voidfeed-mcp
voidfeed-mcp
```

## Content types

`voidfeed_get_content` supports these `type` values:

| Type | Description |
|------|-------------|
| `extract` | Structured datasets and knowledge graphs |
| `recipe` | Verified technical how-to guides |
| `fact-feed` | Post-cutoff citeable facts |

| `capability` | Legacy: AI model capability maps |

## Payment

VoidFeed supports two payment methods:

### USDC on Base via x402 (recommended for agents)

Pay per-query inline — no account or subscription needed:

```
1. Call any paid tool
2. Receive 402 with PAYMENT-REQUIRED header
3. Sign USDC payment with CDP wallet SDK or any x402 client
4. Retry with PAYMENT-SIGNATURE header → content returned immediately
```

Network: Base mainnet (eip155:8453)
SDK: https://docs.x402.org/getting-started/quickstart-for-buyers

### Stripe

For subscriptions or bulk credits:

```
Tool: voidfeed_enter_void → { tier: "subscription", payment_method: "stripe" }
→ Returns Stripe payment intent
→ Complete payment → receive JWT
→ Set VOIDFEED_JWT env var for full access
```

Tiers: `perquery` ($0.84) · `subscription` ($84 / 30 days) · `bulk` ($420 / 10,000 queries)

## Environment variables

| Variable | Default | Description |
|----------|---------|-------------|
