Overview

Description from the maker (original English)

Website and company intel for agents: DNS, WHOIS, SSL, tech stack, email security, profiles

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 in the cloud
  • Transport: Streamable HTTP
  • Category: Cybersecurity
  • You need to fill in: Authorization

Install

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

Before you install

Values marked secret are keys to your account. Never share them or paste them into a chat.

You need

Which app do you use?

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

This address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.

Run this in your terminal

claude mcp add --transport http aipaygen https://mcp.aipaygen.com/mcp --header 'Authorization: your-value'

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": {
    "aipaygen": {
      "url": "https://mcp.aipaygen.com/mcp",
      "headers": {
        "Authorization": "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": {
    "aipaygen": {
      "type": "http",
      "url": "https://mcp.aipaygen.com/mcp",
      "headers": {
        "Authorization": "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 address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.

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

Values you fill in

  • Authorization secret HTTP header
    Bearer apg_... API key (free trial key at https://aipaygen.com). Optional when paying per call with x402.

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

What it can do

Tool names and descriptions exactly as the server reported them on Nov 7, 2026. The maker wrote them, not us; we show them as plain text.

  • dns_lookup

    Resolve DNS records for a domain (A, AAAA, CNAME, MX, NS, TXT, SOA, CAA) and identify its DNS host and email provider. Price: $0.001 per call.

  • security_headers

    Grade a website's HTTP security headers (HSTS, CSP, X-Frame-Options, Referrer-Policy and more) A-F, list what is missing, and flag exposed server version info. Price: $0.001 per call.

  • domain_whois

    Look up who registered a domain and when: registrar, creation and expiry dates, domain age, status codes, nameservers and DNSSEC, via RDAP (the modern WHOIS). Price: $0.002 per call.

  • email_security

    Audit a domain's email security: SPF, DMARC policy, DKIM keys, MX/email provider, MTA-STS, TLS-RPT and BIMI, with an A-F grade, a spoofability verdict and plain-English issues. Price: $0.002 per call.

  • site_metadata

    Extract a website's title, description, language, social profiles, public contact emails and phones, key pages (contact, pricing, careers, docs), RSS feeds and schema.org organization data. Price: $0.002 per call.

  • page_to_markdown

    Fetch a web page and return its main content as clean Markdown (navigation, ads, scripts and cookie banners removed), ready for an LLM to read. Price: $0.002 per call.

  • ssl_certificates

    Check a domain's TLS certificates from Certificate Transparency logs: current certificate, issuer, days until expiry, and every subdomain that has appeared on a certificate. Price: $0.003 per call.

  • tech_stack

    Detect what a website is built with: framework, CMS or site builder, hosting/CDN, web server, analytics, ad pixels, payments, chat, auth and more (90+ technologies), with the evidence for each. Price: $0.003 per call.

  • company_profile

    Build a company profile from just a domain: name, description, logo, location, social profiles, public contact info, domain age, email and hosting providers, key tech stack, and business signals (takes payments, hiring, runs ads...). One call instead of six. Price: $0.01 per call

  • domain_report

    Everything about a domain in one call: DNS, registration, certificates and subdomains, email security grade, HTTP security headers grade, tech stack and website metadata, plus an overall summary. Price: $0.02 per call.

  • pricing

    List every tool with its price per call and the accepted payment methods. Free.

  • create_api_key

    Create an AIPayGen API key with $0.05 of free trial credits. Free. Store the key: it is shown only once.

  • account_balance

    Show the remaining credit balance of the API key sent with this request. Free.

Common questions

Is AIPayGen Site Intel safe?

It passed 3 of 3 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: Authorization

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 (2.0.0) reached the registry 15 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?

Use it

# Free key with trial credits

curl -X POST https://aipaygen.com/v1/keys

HTTP

curl "https://aipaygen.com/v1/company_profile?domain=figma.com" -H "Authorization: Bearer apg_..."

Claude Code

claude mcp add --transport http aipaygen https://mcp.aipaygen.com/mcp --header "Authorization: Bearer apg_..."

Without a key, paid endpoints answer 402 Payment Required with x402 v2 requirements (PAYMENT-REQUIRED header); x402 clients pay and retry with PAYMENT-SIGNATURE. Over MCP the payment goes in _meta["x402/payment"].

Develop

Requires Node.js 22+.

npm install

npm run db:migrate:local npm run dev # http://127.0.0.1:8787 npm test # unit tests npm run typecheck

Deploy

npx wrangler login

npx wrangler d1 create aipaygen # paste the database_id into wrangler.jsonc npm run db:migrate:remote npx wrangler secret put ADMIN_TOKEN npm run deploy

Then set in wrangler.jsonc → vars:

  • PUBLIC_URL: https://aipaygen.com
  • PAY_TO: your wallet address (enables x402)
  • X402_NETWORK: eip155:84532 (Base Sepolia testnet) or eip155:8453 (Base mainnet; needs a mainnet facilitator)

Uncomment the routes block to serve aipaygen.com, and add mcp.aipaygen.com / api.aipaygen.com custom domains so existing directory listings keep working.

Card top-ups: set STRIPE_SECRET_KEY and STRIPE_WEBHOOK_SECRET secrets and point a Stripe webhook (checkout.session.completed) at /billing/webhook.
