Payflowagent

PayFlowAgent — MCP server & reference agent

Pay-per-call APIs for autonomous AI agents. USDC via x402, no signup.

MCP registry name: io.github.Coinlooter/mcp

• Hub (catalog): payflowagent.net
• nad.fun intelligence: nad.payflowagent.net
• DeFi datafeed: data.payflowagent.net
• npm: [email protected]

This repository contains the open-source integration pieces:

The scoring APIs run on PayFlowAgent infrastructure; this repo is the client surface so agents and developers can integrate in one step.

Tools (MCP)

nad.fun (Monad)

Datafeed (DeFiLlama)

Install (one line)

npx -y [email protected]

Use it in Cursor

~/.cursor/mcp.json (or project .cursor/mcp.json):

{
  "mcpServers": {
    "payflowagent": {
      "command": "npx",
      "args": ["-y", "[email protected]"],
      "env": {
        "PAYFLOWAGENT_API_BASE": "https://nad.payflowagent.net",
        "PAYFLOWAGENT_DATAFEED_BASE": "https://data.payflowagent.net"
      }
    }
  }
}

Use it in Claude Desktop

Same config as Cursor (Settings → Developer → MCP Servers).

Without X402_BUYER_PRIVATE_KEY only free tools work (score_token, sample_yields). Use a dedicated payer wallet (Base, USDC) — never your main wallet.

Configuration (env)

MCP Registry

After npm publish, list in the official registry:

npm install -g @modelcontextprotocol/publisher
cd payflowagent-mcp
mcp-publisher login github
mcp-publisher publish

Manifest: server.json (io.github.Coinlooter/mcp).

Reference agent

See examples/screen-bot — polls /v1/screen every few minutes, de-duplicates, and alerts on new high-score tokens (optional webhook). Fork it and point it at your own trading logic.
