Overview

AI-generated overview

Local MCP server giving assistants pay-per-call token intelligence and DeFi yield data, with free tools and USDC x402 payments from a wallet.

What you can do
Score and analyze nad.fun tokens: free 0–100 score with risk level and action, plus paid full reports, summaries and ranked screening of fresh tokens (rate-limited free tier). Sample and rank DeFi yield pools from DeFiLlama data, with free previews and paid ranked picks including risk scores and reasons. Paid tools are settled automatically in USDC over x402 from a configured payer wallet.
When to use it
Useful when an assistant needs to evaluate or screen Monad nad.fun tokens or compare DeFi yield opportunities, and you are willing to fund a small dedicated wallet for the paid calls. The free tools alone suit light, rate-limited lookups.
Requirements
Runs locally via npx (Node.js). Optional environment variables set API base URLs for the nad.fun, Datafeed, Enrich and Trust services. Paid tools need X402_BUYER_PRIVATE_KEY for a dedicated Base wallet holding USDC, and optionally X402_BUYER_RPC; without the key only free tools work. Network access required.
Before you install
Paid tools spend real USDC from the wallet whose private key is supplied in X402_BUYER_PRIVATE_KEY; the README advises a dedicated payer wallet, never a main one. The key is a secret stored in the MCP config. Requests go to third-party PayFlowAgent endpoints, and the free score tool is rate-limited.

Installation

In SourceWeft

  1. Open Coinlooter in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

README

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

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.

Install (one line)

bash
npx -y [email protected]

Use it in Cursor

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

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.

Score

50% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

  • Reached in the last 30 days25 pts

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declared10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.

  • Tools listed15 pts

    Answer tools/list without a credential, or ship a package that starts in a sandbox without one.
