What can you do with io.github.cheevahagadog/forency?

  • it talks to https://forency.io and nothing else
  • it sends your API key and the URLs you asked about, nothing more
  • no telemetry, no analytics, no third-party calls
  • detection happens server-side, so it is not in this repo

Forency MCP Server

Let your AI assistant investigate any website's technology stack — CMS, ecommerce platform, JavaScript frameworks, analytics, CRM, marketing automation, payments, chat widgets, CDN, and hosting.

Ask Claude (or Cursor, or any MCP client):

"What tech stack does competitor.com run?"

"Which of these 15 prospects use HubSpot vs Salesforce?"

"Compare the analytics and payment stacks of these three stores."

Two ways to connect

Hosted — no install. If your client supports remote MCP servers, point it at https://forency.io/api/mcp with your API key as a Bearer token. Nothing to download, and you always get the current tools. Also listed on Smithery.

Local — this package. For clients that run MCP servers on your machine:

Install

Add to your MCP config — claude_desktop_config.json, .mcp.json, or your client's equivalent:

{
  "mcpServers": {
    "forency": {
      "command": "npx",
      "args": ["-y", "forency-mcp"],
      "env": { "FORENCY_API_KEY": "fcy_your_key" }
    }
  }
}

Or with Claude Code:

claude mcp add forency -e FORENCY_API_KEY=fcy_your_key -- npx -y forency-mcp

Get a free API key at forency.io — 100 scans/month, no credit card.

Tools

ToolWhat it does
lookup_tech_stack(url)Full technology breakdown for one website
batch_lookup(urls)Up to 25 websites in one call, full detail for each
compare_stacks(urls, categories?)Side-by-side table across sites, optionally filtered to categories like ["CRM", "Analytics"]

Each URL scanned counts as one scan against your plan.

What this package does, and doesn't

This repository is the whole client. It is a thin stdio MCP server that forwards your request to the Forency REST API and formats the reply. Worth knowing before you hand any tool an API key:

  • it talks to https://forency.io and nothing else
  • it sends your API key and the URLs you asked about, nothing more
  • no telemetry, no analytics, no third-party calls
  • detection happens server-side, so it is not in this repo

You can read the entire thing in src/index.ts in about five minutes. Point it somewhere else with FORENCY_API_URL if you want to watch what it sends.

Environment

VariableRequiredDescription
FORENCY_API_KEYYesYour key from forency.io
FORENCY_API_URLNoAPI base URL (defaults to https://forency.io)

A note on detection

Forency reads the HTML and headers a site's server returns. It does not run a browser, so technologies injected purely by client-side JavaScript may not show up — a sparse result means little was detectable, not that a site runs nothing.

Pricing

TierPriceScans/mo
Free$0100
Starter$29/mo1,000
Pro$49/mo10,000
EnterpriseCustomUnlimited

BuiltWith's API starts at $295/mo and Wappalyzer's at $250/mo. Neither ships an MCP server.

Acknowledgements

Forency's detection is built on the technology fingerprints maintained by the **webappanalyzer** project, the community-maintained continuation of Wappalyzer's open-source fingerprint database, which is licensed GPL-3.0. That work is what makes accurate detection possible at this price, and it deserves the credit.

This MCP client contains no fingerprint data or detection code of its own and is released under the MIT license (see LICENSE).
