djd-agent-score-mcp

MCP server for DJD Agent Score — a reputation scoring API for AI agent wallets on Base.

This server exposes the DJD Agent Score REST API as Model Context Protocol tools, so any MCP-compatible agent (Claude, GPT, Gemini, LangChain, etc.) can call scoring endpoints natively.

Configuration

Claude Desktop

Add to ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows):

{
  "mcpServers": {
    "djd-agent-score": {

      "args": ["-y", "djd-agent-score-mcp"]
    }
  }
}

Cursor

Add to .cursor/mcp.json in your project root:

{
  "mcpServers": {
    "djd-agent-score": {
      "command": "npx",
      "args": ["-y", "djd-agent-score-mcp"]
    }
  }
}

Claude Code

Add to your project's .mcp.json:

{
  "mcpServers": {
    "djd-agent-score": {
      "command": "npx",
      "args": ["-y", "djd-agent-score-mcp"]
    }
  }
}

Generic MCP Client (Streamable HTTP)

Start the server in HTTP mode:

TRANSPORT=http PORT=3000 npx djd-agent-score-mcp

Then connect your MCP client to http://localhost:3000/mcp.

Environment Variables

| Variable | Default | Description | |----------|---------|-------------| | DJD_BASE_URL | https://djd-agent-score.fly.dev | API base URL (use http://localhost:3001 for local dev) | | DJD_TIMEOUT_MS | 10000 | Request timeout in milliseconds | | TRANSPORT | stdio | Transport mode: stdio or http | | PORT | 3000 | HTTP server port (only used when TRANSPORT=http) |

Development

git clone <repo-url>
cd djd-agent-score-mcp
npm install
npm run build
npm start

To point at a local API during development:

DJD_BASE_URL=http://localhost:3001 npm start

x402 Payment

Some endpoints require x402 micropayments. When an agent calls a paid tool, the API responds with HTTP 402 and payment instructions. Your agent framework must:

1. Detect the 402 response
2. Complete the x402 payment (USDC on Base)
3. Retry the request with the payment proof

The MCP server surfaces the 402 details in the tool's error response so the agent can handle it.
