Which app do you use?

ClaudeClaude CodeCursorVS CodeChatGPT

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.

Or run it on your computer

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

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

Run this in your terminal

claude mcp add --transport http forency https://forency.io/api/mcp --header 'Authorization: your-value'

Or run it on your computer

claude mcp add forency --env FORENCY_API_KEY=your-value -- npx -y forency-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": {
    "forency": {
      "url": "https://forency.io/api/mcp",
      "headers": {
        "Authorization": "your-value"
      }
    }
  }
}

Or run it on your computer

Open in Cursor

Or copy the settings yourself

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

{
  "mcpServers": {
    "forency": {
      "command": "npx",
      "args": [
        "-y",
        "forency-mcp"
      ],
      "env": {
        "FORENCY_API_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": {
    "forency": {
      "type": "http",
      "url": "https://forency.io/api/mcp",
      "headers": {
        "Authorization": "your-value"
      }
    }
  }
}

Or run it on your computer

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{

      ],
      "env": {
        "FORENCY_API_KEY": "your-value"
      }
    }

Common questions

Is Forency 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?

You need to fill in: FORENCY_API_KEY, Authorization

Does it run on my computer or in the cloud?

Either way works: install it on your computer or connect to the cloud version.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.1.0) reached the registry 2 months 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?

README from the maker

Open the README

Copied from the maker’s repo as written. PopNx MCP has not reviewed or endorsed it. HTML, images and scripts are removed. Links lead off this site.

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

Tool	What 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

Variable	Required	Description
`FORENCY_API_KEY`	Yes	Your key from forency.io
`FORENCY_API_URL`	No	API 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

Tier	Price	Scans/mo
Free	$0	100
Starter	$29/mo	1,000
Pro	$49/mo	10,000
Enterprise	Custom	Unlimited

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).
