Overview

Description from the maker (original English)

Authorized privacy and exposure checks for people and agents; USDC on Base via x402.

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.

Install

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

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on the maker’s server: what you ask it goes through their server.
  • The registry lists no key to fill in.

Common questions

Is Phantomoperator 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 in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.1.0) reached the registry 8 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

PhantomOperator

PhantomOperator is a pay-per-call privacy and public-exposure analysis service for authorized users and AI agents. It provides structured checks for web metadata leakage, public-web exposure, breach indicators, privacy posture, and wallet hygiene.

Authorization required: Only assess URLs, identities, email addresses, wallets, and systems you own or are expressly authorized to assess. Do not submit seed phrases, passwords, API keys, or other secrets.

Payments

Working paid rail: Base USDC via x402

Paid routes at POST /skills/* use x402 v2 exact payments.

An unpaid valid request receives HTTP 402 Payment Required. An x402-compatible client signs the stated payment requirement and retries the same request. Never send a plain ERC-20 transfer as a substitute for the x402 payment credential.

Optional privacy rail: Monero invoices

A production Monero flow is included but is disabled by default. It requires a privately reachable, view-only monero-wallet-rpc, a fixed XMR/USD quote configuration, and a local proof secret. Once configured, a client:

  1. requests POST /billing/monero-quote with { "skillId": "metadata-audit", "input": { ... } };
  2. receives a unique wallet subaddress, exact atomic-XMR amount, expiry, and status URL;
  3. pays the amount, then polls GET /billing/monero-invoice/:invoiceId until required confirmations are reached;
  4. retries the requested skill with X-Payment-Method: monero and the returned X-Payment proof.

The service uses the view-only wallet RPC only to allocate subaddresses and verify incoming confirmed amounts. It never needs a Monero spend key. Configuration names are documented in .env.example.

Available operations

The canonical schemas, payment requirements, and examples are generated at /openapi.json. Prices are denominated in USDC and may be read from that document before payment.

Agent quickstart

  1. Fetch /openapi.json, /.well-known/x402, or /mcp.
  2. Validate that the target and submitted information are authorized and non-sensitive.
  3. Call the selected POST /skills/ route with valid JSON.
  4. On 402, inspect the returned x402 requirement and retry using an x402-compatible Base-USDC client.
  5. Validate the returned JSON against the published operation schema.

For MCP clients, send JSON-RPC 2.0 initialize, tools/list, and tools/call requests to POST /mcp. The paid-tool handoff returns the exact HTTP route and payment guidance.

Local development

npm install

cp .env.example .env npm test npm start

The server defaults to port 3000. Set PUBLIC_BASE_URL to the deployed HTTPS origin and use a protected .env file. See .env.example for non-secret configuration names. Do not commit credentials, payment keys, private keys, or customer data.

Deployment and discovery

The public service publishes OpenAPI, x402, A2A, ERC-8004, MCP, llms.txt, robots, and sitemap discovery documents. Its current distribution work includes ERC-8004, MPPScan, Global A2A Registry, Agent Tools, 402 Index, Coinbase Bazaar, and a Bankr skills pull request. A directory is only described as listed after acceptance is verifiable; indexes may crawl asynchronously.

Privacy and telemetry

/usage displays aggregate settled-service telemetry. It intentionally excludes request bodies, raw IP addresses, customer wallets, and payment credentials. See TERMS.md for the service scope and limits.
