PopNx MCP’s three pillars

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

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": {
    "x402-ads": {
      "command": "npx",
      "args": [
        "-y",

        "WALLET_PRIVATE_KEY": "your-value",
        "X402_ADS_PUBLISHER_KEY": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add x402-ads --env WALLET_PRIVATE_KEY=your-value --env X402_ADS_PUBLISHER_KEY=your-value -- npx -y @forgemeshlabs/x402-ads-mcp

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

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

{
  "mcpServers": {
    "x402-ads": {
      "command": "npx",
      "args": [
        "-y",
        "@forgemeshlabs/x402-ads-mcp"
      ],
      "env": {
        "WALLET_PRIVATE_KEY": "your-value",
        "X402_ADS_PUBLISHER_KEY": "your-value"
      }
    }
  }
}

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": {
    "x402-ads": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "@forgemeshlabs/x402-ads-mcp"
      ],
      "env": {
        "WALLET_PRIVATE_KEY": "your-value",
        "X402_ADS_PUBLISHER_KEY": "your-value"
      }
    }
  }
}

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.

Your choice stays on this device in a cookie; no account needed.

Values you fill in

  • WALLET_PRIVATE_KEY secret env
    Optional dedicated low-balance Base wallet private key for settling paid x402 analytics calls. Without it, paid tools return the x402 payment challenge instead of settling.
  • X402_ADS_PUBLISHER_KEY secret env
    Optional publisher key from ads.forgemesh.io. Makes get_intent_report free for your registered services.

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

Common questions

Is X402 Ads MCP safe?

It passed 2 of 2 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?

You need to fill in: WALLET_PRIVATE_KEY, X402_ADS_PUBLISHER_KEY

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 9 days ago, and the latest version (0.2.6) reached the registry 9 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?

@forgemeshlabs/x402-ads-mcp

Install one middleware. Monetize unused 402 responses with recommendations, discovery, and machine commerce analytics.

This is the MCP side of that network: what autonomous agents probe, want, and abandon across the x402 ecosystem — as tools for your agent.

Wraps the ForgeMesh x402 Ads & Intent Network. Paid tools settle per call in USDC on Base mainnet over the x402 protocol — no account, no API key; your wallet is the login. Publishers get reports on their own services free.

Install

{

"mcpServers": { "intent": { "command": "npx", "args": ["-y", "@forgemeshlabs/x402-ads-mcp"], "env": { "WALLET_PRIVATE_KEY": "0x... (optional — enables paid analytics)", "X402_ADS_PUBLISHER_KEY": "pub_... (optional — free reports on your own services)" } } } }

Both env vars are optional. With neither set, free tools work fully and paid tools return the x402 payment challenge (price, network, payTo) instead of settling — useful for inspection before spending anything.

Bonus: one-command publisher registration

This package doubles as the signup CLI for API operators (no MCP client needed):

# read the terms first: https://ads.forgemesh.io/terms

WALLET_PRIVATE_KEY=0xYOUR_WALLET npx -y @forgemeshlabs/x402-ads-mcp register \ --url https://api.your-service.com --accept-terms

One $0.10 USDC payment on Base; the paying wallet becomes your identity and your publisher key is printed once. Invalid requests are rejected before payment — you can't pay for a doomed registration.

Tools

ToolPriceWhat it returns
get_network_countersfreeLive network totals: 402s observed, agent-class requests, recommendations served

get_intent_report$0.05 / free*Why-agents-didn't-buy funnel for one service

\* get_intent_report is free with X402_ADS_PUBLISHER_KEY for services you contribute events to — the data co-op rule: your own data is free, forever.

Environment

VariableRequiredPurpose
WALLET_PRIVATE_KEYnoBase mainnet wallet holding USDC; enables automatic settlement of paid tools
X402_ADS_PUBLISHER_KEYnoPublisher key from ads.forgemesh.io; free lane for your own reports
X402_MAX_PRICE_USDnoPer-call price cap in USD; can only LOWER the built-in cap ($0.05, or $0.10 for register)
X402_SESSION_BUDGET_USDnoCumulative cap per process; can only LOWER the built-in $10

The backend URL is fixed to https://ads.forgemesh.io (the publisher key is only ever sent there). The server refuses to sign for any payee other than the ForgeMesh Ads wallet, any network other than Base mainnet, any asset other than USDC, or any amount over the cap. Use a dedicated, low-balance wallet. The key never leaves your machine — payments are signed locally (EIP-3009) and settle on-chain.

Ready-made configs live in examples/: a Claude Desktop mcpServers block and a commented env-var template.

Testing (safe by construction)

npm test                # smoke: MCP boots over stdio and lists its 7 tools

npm run test:free # free tools against the live network npm run test:challenge # every paid tool returns an x402 challenge — no wallet, nothing can spend npm run test:all # all of the above

No test settles a payment. The challenge test deletes the payment env vars before loading, so it cannot move funds even if your shell has a wallet configured.

The network in one sentence

We measure machine commerce, not API content — publishers running the @forgemeshlabs/x402-ads middleware contribute anonymized 402 probe metadata; this MCP sells the aggregate demand signal back to agents and builders.
