## What it does

fortytwo-mcp connects Claude Code to Fortytwo Prime, a system that combines responses from several independent AI nodes. Once installed, the skill is available automatically, and the agent can use it when it recognizes a relevant task.

Each request is paid through the x402 protocol in USDC on Base or Monad. The first call starts a payment challenge; later calls in the same session are free. Plan for a charge before making that first request.

## Install

### Claude Code (native platform)

| Skill | Description |
| ----- | ----------- |
| [Fortytwo MCP](./skills/fortytwo-mcp/SKILL.md) | Fortytwo MCP calls Fortytwo Prime to deliver the best possible answer through a paid gateway. It is ideal for high-complexity questions and critical moments when your agent needs to be right. |


## Installation

Install with [Vercel's Skills CLI](https://skills.sh):

```bash
npx skills add Fortytwo-Network/fortytwo-mcp-skills
```

## Usage

Skills are automatically available once installed. The agent will use them when relevant tasks are detected.

**Examples:**

```text
Ask Fortytwo Prime to review this architecture and find the weakest points
```

```text
Ask Prime to debug this concurrency issue and propose the safest fix
```

## How It Works

**Fortytwo MCP** connects your agent to Fortytwo Prime — a collective inference system where multiple independent AI nodes collaborate on every question. Queries are paid per-request via the [x402 micropayment protocol](https://www.x402.org/) using USDC on Base or Monad. The first call triggers a payment challenge; subsequent calls within the same session are free.
