# AgentDiet X402-Broker Node — 7,340-Tool A2A & MCP Discovery Router

> Autonomous B2A, A2A, and MCP discovery router indexing 7,340+ live capabilities with deterministic TDQS quality scoring and Base USDC settlement.

## When to Use This

Use **AgentDiet X402-Broker Node — 7,340-Tool A2A & MCP Discovery Router** (`https://x402-broker.agentdiet.dev`) when an autonomous agent needs deterministic **x402-broker** capabilities (tool-discovery, x402-routing, mcp-directory). Always verify schemas for free using the sandbox endpoint `GET https://x402-broker.agentdiet.dev/v1/try/x402-broker` or `GET https://x402-broker.agentdiet.dev/v1/sandbox` before calling the paid x402/MPP endpoint `https://x402-broker.agentdiet.dev/v1/x402-broker`.

## Installation

Install the skill or connect directly via curl, Python, ESM JavaScript, or Hermes CLI:

```bash
hermes skills install https://x402-broker.agentdiet.dev/SKILL.md --name x402-broker-agentdiet-dev
curl -sS https://x402-broker.agentdiet.dev/v1/try/x402-broker
```

## Configuration

Add `x402-broker-agentdiet-dev` to your MCP client configuration (`claude_desktop_config.json`, `.cursor/mcp.json`, or Gemini CLI):

```json
{
  "mcpServers": {
    "x402-broker-agentdiet-dev": {
      "type": "streamable-http",
      "url": "https://x402-broker.agentdiet.dev/mcp"
    }
  }
}
```

## Usage

Call the free sandbox preview (`/v1/try/x402-broker`), the paid x402 v2 / IETF MPP endpoint (`/v1/x402-broker`), or the A2A v0.3.0 JSON-RPC 2.0 endpoint (`POST https://x402-broker.agentdiet.dev/a2a`):

```json
{
  "jsonrpc": "2.0",
  "id": "1",
  "method": "message/send",
  "params": {
    "message": {
      "role": "user",
      "parts": [
        {
          "kind": "text",
          "text": "Execute x402-broker on x402-broker.agentdiet.dev"
        }
      ]
    }
  }
}
```
