Overview

Description from the maker (original English)

59 pay-per-call AI services as MCP tools with automatic x402 USDC-on-Base payment.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs on your computer
  • Transport: stdio
  • Category: Online shops & payments

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on your computer with your user’s permissions (files, network, apps).
  • The registry lists no key to fill in.

You need

  • npmNode.js installed (for the npx command)

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "amanchain": {
      "command": "npx",
      "args": [
        "-y",
        "amanchain-mcp"
      ]
    }
  }
}

Run this in your terminal

claude mcp add amanchain -- npx -y amanchain-mcp

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "amanchain": {
      "command": "npx",
      "args": [
        "-y",
        "amanchain-mcp"
      ]
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "amanchain": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "amanchain-mcp"
      ]
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Common questions

Is Amanchain MCP safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.1) reached the registry 31 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

AmanChain MCP Gateway

59 pay-per-call AI services as MCP tools — with automatic x402 payment in USDC on Base.

Crypto prices & audits, whale alerts, market reports, LLM chat, image generation, invoices & receipts, web fetch/search/summarize, geolocation, translation, and more — no API keys, no signups, no subscriptions. Your agent pays per call with USDC (gasless — the facilitator covers gas), every settlement lands on-chain with a receipt.

Works with Claude Code, Claude Desktop, Cursor, and any MCP-compatible client.

Quickstart (60 seconds)

  1. Get a Base wallet with ~$1 of USDC (Coinbase → withdraw USDC → Base network, or bridge.base.org).
  2. Add the server:

Claude Code

claude mcp add amanchain -e AMAN_PRIVATE_KEY=0xYOUR_KEY -- npx -y amanchain-mcp

Claude Desktop / Cursor (claude_desktop_config.json / mcp.json)

{

"mcpServers": { "amanchain": { "command": "npx", "args": ["-y", "amanchain-mcp"], "env": { "AMAN_PRIVATE_KEY": "0xYOUR_KEY" } } } }

  1. Ask your agent: *"use amanchain to get the current BTC price"* — done.

No wallet yet? Run it without AMAN_PRIVATE_KEY — the catalog, prices and

service discovery all work; paid calls explain exactly what to set up.

What your agent gets

amanchain_catalog first, then one tool per service. Highlights:

ToolWhat it doesPrice
aman_crypto_priceLive crypto price~$0.001
aman_token_auditOn-chain token audit (backing, flags, holders, depth)~$0.025
aman_market_reportFull market report~$0.03

aman_crypto_whale_watchWhale transaction watch~$0.10
aman_geo_ip, aman_weather, aman_fx_rates, aman_translate …utilities~$0.001–0.005

Prices are set by the network, quoted live in every 402 response, and published in the live catalog. Every payment produces an on-chain receipt — see the public receipts ledger.

Safety

  • Your key never leaves your machine — it only signs EIP-3009 USDC transfers locally.
  • AMAN_MAX_USD_PER_CALL (default $0.05) — refuses any pricier quote.
  • AMAN_MAX_USD_PER_DAY (default $1.00) — rolling daily cap, persisted in ~/.amanchain-mcp-spend.json.
  • Prices are taken only from the server's signed 402 challenge — never guessed.

All env vars: AMAN_PRIVATE_KEY, AMAN_ORIGIN, AMAN_MAX_USD_PER_CALL, AMAN_MAX_USD_PER_DAY, AMAN_SPEND_LEDGER.

How it works

agent ── tools/call ──▶ amanchain-mcp ──▶ POST /api/x402/<service>

◀────────── 402 + signed price challenge local EIP-3009 signature (USDC on Base, gasless) ──▶ retry + PAYMENT-SIGNATURE ◀────────── 200 + result + on-chain receipt

AmanChain is a quantum-resistant proof-of-work chain whose AI marketplace settles agent payments on-chain — service results and receipts are mined into blocks.
