What Dupin Diagnoses

Schema.org

Structured data AI systems can parse and cite. FAQPage, HowTo, speakable markup — the signals that make your content quotable.

Crawler Architecture

GPTBot, PerplexityBot, BingBot, Claude-SearchBot, OAI-SearchBot, Applebot — training bots, search bots, and retrieval bots need different access rules. Most sites treat them identically. That’s wrong.

Citability Scoring

AI cites 50–150 word chunks 2.3× more. Answer-first paragraphs under 40 words get 67% more citations. Dupin scores every section.

Technical GEO

llms.txt compliance, canonical URLs, hreflang for multilingual sites, and priority-ranked fixes you can implement today.

Content Structure

Heading hierarchy, semantic HTML, passage sizing for AI citation, author attribution (E–E–A–T). Answer-first content gets cited 44% more.

How It Works

Two paths, same methodology.

Audit Pass — automated scan

Submit

Enter a URL. No account, no MCP, no setup.

Scan

Our service crawls your public site and runs 30+ earned-score checkpoints across 7 sections.

Report

Branded report with scored sections, findings, and exact fix code — delivered by email.

Inspector & Agency — MCP agent

Pick a plan, get your API key instantly.

Connect

Add Dupin to your MCP client — Claude Code, Cursor, VS Code, Windsurf, or Codex. One config entry.

Audit

Tell your AI: “audit this site” — Dupin reads your codebase, reasons about your situation, and prescribes fixes.

Example: Claude Code config

{
  "mcpServers": {
    "dupin": {
      "command": "npx",
      "args": ["@funkatorium/dupin-mcp"],
      "env": { "DUPIN_API_KEY": "dk_live_xxxxx" }
    }
  }
}

Same config structure works in Cursor, VS Code, and Windsurf. Full setup guide for all platforms →

Data Sovereignty

We tell you exactly what touches what.

Audit Pass: Our service crawls your public-facing site — the same pages any visitor can see. Your codebase, internal files, and private data are never accessed. Inspector & Agency: Dupin runs as an MCP server on your local machine. Your files, your code, your results — all stay on your hardware. Nothing is sent to our servers except a lightweight API key validation.

FAQ

What is SEO?

Search Engine Optimization — the practice of making your website rank higher in Google, Bing, and other traditional search engines. Keywords, meta tags, page speed, backlinks, structured data. It’s been the foundation of online visibility for 25 years, and it still matters — but it’s no longer enough on its own. Dupin audits your technical SEO alongside GEO and AEO so nothing falls through the cracks.

What is GEO?

Generative Engine Optimization. Traditional SEO gets you into Google results. GEO gets you cited by AI assistants — ChatGPT, Claude, Perplexity, Apple Intelligence. Different systems, different crawlers (GPTBot, PerplexityBot, Claude-SearchBot, BingBot, Applebot), different rules. If you only optimize for Google, you’re invisible to 40% of modern search behavior.

What is AEO?

Answer Engine Optimization. When someone asks ChatGPT, Perplexity, or Claude a question, the AI pulls from a handful of sources and synthesizes an answer. AEO is the practice of making your content the source it pulls from. That means structured data AI can parse, crawler access configured correctly (most sites block the bots they should be letting in), and content formatted in citable chunks — not walls of marketing copy. It’s the newest layer of search optimization, and most agencies don’t offer it yet because the field barely existed before 2025. Dupin covers it in every plan.

What does Dupin actually audit?

Seven scored sections: Schema.org structured data, robots.txt AI crawler architecture (GPTBot, PerplexityBot, BingBot, Claude-SearchBot, OAI-SearchBot, Applebot — training bots vs. retrieval bots vs. search bots), meta tags and Open Graph, content structure and AEO (heading hierarchy, semantic HTML, author attribution, passage sizing for citability), sitemap validation, crawlability diagnostics, and llms.txt compliance. The Audit Pass runs 30+ earned-score checkpoints grounded in peer-reviewed GEO research — no AI reasoning, just fast and consistent rule-based analysis with exact fix code. Inspector and Agency subscribers get Dupin’s MCP agent on top, which reads your actual codebase and reasons about your specific situation.

Which AI models does Dupin work with?

Dupin works with any MCP-compatible client — Claude Code, Cursor, VS Code, Windsurf, and OpenAI Codex. Gemini doesn’t support MCP yet. We recommend running on Claude Opus for the deepest analysis, but Sonnet, Haiku, and non-Anthropic models work too — the methodology is model-agnostic.

Does my data touch your servers?

Audit Pass: Our service crawls your public-facing site — the same pages any browser can visit. We never access your codebase, internal files, or anything behind authentication. Inspector & Agency: Dupin runs locally on your machine via MCP. Your files stay on your hardware — the only thing that hits our infrastructure is API key validation. Read our full privacy policy.

Can I cancel anytime?

Yes. Inspector and Agency plans cancel immediately with no penalty. You keep access until the end of your billing period. Audit Passes never expire.

What is MCP?

Model Context Protocol — an open standard for connecting AI assistants to external tools. Dupin connects to Claude Code (or any MCP-compatible client) as a specialist tool. You install it once, and it’s available whenever you need an audit. No browser extension, no SaaS dashboard — it lives in your development environment.

What is MCP?

MCP (Model Context Protocol) is an open standard that lets your AI assistant connect to external tools. Dupin ships as an MCP server — a small program that gives your AI new capabilities. You add one config entry, and Dupin is available inside your editor.

Your code and files stay on your machine. The agent’s methodology comes to you — nothing gets uploaded.

What You Need

An MCP-compatible editor (see platforms below)
Node.js installed on your machine (nodejs.org — download the LTS version)
Your API key (you’ll get this after subscribing)

Pick Your Platform

Claude Code

Step 1: Open your terminal and run Claude Code. Type /settings or find the file at:

~/.claude/settings.json

Step 2: Add this inside the "mcpServers" section. Replace dk_live_xxxxx with your real API key:

"dupin": {
  "command": "npx",
  "args": ["@funkatorium/dupin-mcp"],
  "env": { "DUPIN_API_KEY": "dk_live_xxxxx" }
}

Step 3: Restart Claude Code. Type audit https://yoursite.com — Dupin will respond.

Cursor

Step 1: Open Cursor Settings (Cmd+Shift+P → “Cursor Settings”) and navigate to the MCP tab, or edit directly:

~/.cursor/mcp.json

Step 2: Add this to the "mcpServers" section:

"dupin": {
  "command": "npx",
  "args": ["@funkatorium/dupin-mcp"],
  "env": { "DUPIN_API_KEY": "dk_live_xxxxx" }
}

Step 3: Restart Cursor. Open the chat and ask it to audit your site.

VS Code

Step 1: Make sure you have the Copilot Chat extension installed. Edit the MCP config file:

.vscode/mcp.json (in your project folder)

Step 2: Add this to the "servers" section:

"dupin": {
  "type": "stdio",
  "command": "npx",
  "args": ["@funkatorium/dupin-mcp"],
  "env": { "DUPIN_API_KEY": "dk_live_xxxxx" }
}

Step 3: Reload VS Code (Cmd+Shift+P → “Reload Window”).

Windsurf

Step 1: Open the MCP configuration file:

~/.codeium/windsurf/mcp_config.json

Step 2: Add this to the "mcpServers" section:

"dupin": {
  "command": "npx",
  "args": ["@funkatorium/dupin-mcp"],
  "env": { "DUPIN_API_KEY": "dk_live_xxxxx" }
}

Step 3: Restart Windsurf. The agent will be available in Cascade.

Codex (OpenAI)

Step 1: Open your Codex MCP configuration file:

~/.codex/config.json

Step 2: Add this to the "mcpServers" section:

"dupin": {
  "command": "npx",
  "args": ["@funkatorium/dupin-mcp"],
  "env": { "DUPIN_API_KEY": "dk_live_xxxxx" }
}

Step 3: Restart Codex. Ask it to audit your site — Dupin will handle the rest.

Verify It Works

After adding the config and restarting your editor:

Open your AI chat
Type: audit https://yoursite.com
If Dupin responds and starts analyzing, you’re set

Troubleshooting

“Command not found: npx”

Node.js is not installed or not in your PATH. Download it from nodejs.org (LTS version). After installing, close and reopen your terminal.

“Invalid API key”

Make sure your key starts with dk_live_ and has no trailing spaces. You can find your key in the confirmation email you received after subscribing.

The agent doesn’t appear in my AI chat

Did you restart your editor after adding the config? Most MCP clients only load servers on startup. Close the app fully and reopen it. In Claude Code, exit with Ctrl+C and run claude again.

I pasted the config but nothing changed

Check that your JSON is valid — a missing comma or bracket will silently break the file. Paste your entire config file into your AI chat and ask: “Is this valid JSON?” It will find the error instantly.
