  • PAYFLOWAGENT_DATAFEED_BASE — Base URL of the Datafeed API (default https://data.payflowagent.net).

PayFlowAgent suite: token intel, DeFi, enrich, Base trust (x402).

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:

PathWhat
/ (root)payflowagent-mcp — MCP server for Cursor, Claude Desktop, and custom agents.
examples/screen-bot/Reference polling bot: finds high-score nad.fun tokens every few minutes.

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)

ToolPriceDescription
score_tokenfree0–100 score, riskLevel, action (rate-limited).
decide_tokenx402Full report: factors, graduation, momentum.
token_summaryx402Graduation progress + momentum (cheap entry).
screen_tokensx402Ranked list of pre-scored fresh tokens.

Datafeed (DeFiLlama)

ToolPriceDescription
sample_yieldsfreeTop yield pools + 3-item opportunity preview (score + reasons).
yield_opportunitiesx402Ranked yield picks with risk score & explainable reasons.

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)

VariableDefaultPurpose
PAYFLOWAGENT_API_BASEhttps://nad.payflowagent.netnad.fun API base URL.
PAYFLOWAGENT_DATAFEED_BASEhttps://data.payflowagent.netDatafeed API base URL.
X402_BUYER_PRIVATE_KEY—Payer wallet key (Base, USDC). Enables paid tools.
X402_BUYER_RPChttps://mainnet.base.orgPayment RPC (optional).

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.

Develop locally

npm install
npm run typecheck
npm run build      # emits dist/
npm start          # stdio server from source (tsx)

Publish to npm

npm run build
npm publish

How do I install Payflowagent?
Copy the stdio config for Cursor, Claude Desktop, Claude Code, or VS Code on this page. It uses the publisher's install, not a PlugMCP proxy.
Does Payflowagent need an API key?
The publisher lists these environment variables: X402_BUYER_PRIVATE_KEY, PAYFLOWAGENT_API_BASE, PAYFLOWAGENT_DATAFEED_BASE, PAYFLOWAGENT_ENRICH_BASE, PAYFLOWAGENT_TRUST_BASE, X402_BUYER_RPC.
What transport does Payflowagent use?
Payflowagent runs locally over stdio.
When was Payflowagent last checked?
Last checked 2026-10-16. PayFlowAgent suite: token intel, DeFi, enrich, Base trust (x402).

No tool list yet. Remote servers get one after the first health check.
