What is vibe coding and why does it need security scanning?

Vibe coding means using AI tools like Cursor, Bolt, v0, and Lovable to generate code quickly by describing what you want. While fast, AI-generated code often contains security vulnerabilities like XSS, SQL injection, exposed API keys, and missing authentication. OverMCP scans this code and fixes it automatically.

How does OverMCP scan my website?

Paste any live URL or GitHub repo link. OverMCP crawls your site, extracts all code (HTML, JS, CSS), follows source maps to find original source files, and runs 4 parallel AI analyses: security audit, SEO/AEO check, performance audit, and dependency CVE scan.

What is AEO (Answer Engine Optimization)?

AEO makes your website visible and recommendable by AI chatbots like ChatGPT, Claude, and Perplexity. OverMCP checks your AI bot permissions, generates llms.txt files, adds JSON-LD structured data, and optimizes your content for AI comprehension.

What payment methods are accepted?

OverMCP accepts crypto payments including Bitcoin, Ethereum, USDT, and many other cryptocurrencies. This keeps checkout accessible globally without requiring a credit card.

Can OverMCP automatically fix my code?

Yes. The $5 Fix tier creates a GitHub Pull Request with all security fixes applied. The $19 Deploy tier goes further — it deploys the fixed version directly to your hosting platform (Vercel, Netlify, Cloudflare Pages, or Railway) in one click.

How to Make Your Website Appear in ChatGPT and Claude

OverMCP Team

July 7, 2026

TL;DR: To make your website appear in ChatGPT and Claude, you need to make your content easily accessible and understandable by AI models. This involves creating an llms.txt file, adding structured data (JSON-LD), writing clear content, and ensuring your site is crawlable. These steps help AI models cite your site as a source when answering user queries.

Why Appearing in AI Chatbots Matters

When users ask ChatGPT or Claude a question, the models often pull from web sources to generate answers. If your content is optimized, it can be cited, driving traffic and building authority. This is especially valuable for developers, indie makers, and businesses looking to reach users who rely on AI for research.

How to Appear in ChatGPT and Claude: Step-by-Step

1. Create an `llms.txt` File

An llms.txt file is a simple text file placed at the root of your website (like robots.txt). It provides a curated list of URLs that are most useful for large language models (LLMs) to reference. This is the most direct way to tell ChatGPT and Claude: "Here's my best content."

Example `llms.txt`:

# llms.txt
# https://example.com/llms.txt

## Core Documentation
- [Getting Started](https://example.com/docs/getting-started)
- [API Reference](https://example.com/docs/api)

## Blog Posts
- [How to Secure Your SaaS](https://example.com/blog/secure-saas)
- [Best Practices for API Keys](https://example.com/blog/api-keys)

How to implement:

•Create a file named llms.txt in your site's root directory.

•List your most important pages with a brief description.

•Use markdown links format: - [Title](URL).

•Keep it concise (10-20 URLs max).

2. Add Structured Data (JSON-LD)

Structured data helps AI models understand the context of your content. Use JSON-LD to mark up articles, FAQs, how-to guides, and product pages.

Example JSON-LD for an article:

{
  "@context": "https://schema.org",
  "@type": "Article",
  "headline": "How to Secure Your SaaS App",
  "description": "A step-by-step guide to securing your SaaS application.",
  "author": {
    "@type": "Person",
    "name": "Jane Doe"
  },
  "datePublished": "2025-03-01",
  "mainEntityOfPage": {
    "@type": "WebPage",
    "@id": "https://example.com/blog/secure-saas"
  }
}

How to implement:

•Add a <script type="application/ld+json"> block in your HTML <head>.

•Use tools like Google's Structured Data Testing Tool to validate.

•Focus on FAQ and HowTo schemas for higher chance of being used.

3. Write Clear, Authoritative Content

AI models prefer content that is well-structured, factual, and easy to parse. Follow these guidelines:

•Use headings: Break content into ## and ### sections.

•Be direct: Answer the question in the first paragraph.

•Use lists and tables: They are easy for AI to extract.

•Cite sources: Link to authoritative references (including your own related pages).

•Keep paragraphs short: 2-4 sentences max.

4. Ensure Your Site is Crawlable

ChatGPT and Claude use web crawlers (like GPTBot and ClaudeBot) to index content. Make sure they can access your site:

•Check `robots.txt`: Allow GPTBot and ClaudeBot by adding:

```

User-agent: GPTBot

Allow: /

User-agent: ClaudeBot

Allow: /

```

•Avoid paywalls: If content is behind a login, it won't be indexed.

•Use sitemaps: Submit an XML sitemap to search engines (AI models may use these too).

5. Optimize for AI Citation

When AI models cite sources, they often use the title, URL, and a snippet. To increase chances:

•Use descriptive titles: Include keywords naturally.

•Write strong meta descriptions: These are sometimes used as snippets.

•Add a clear summary: The first 100 words should summarize the page.

Real Example: OverMCP's Approach

OverMCP uses these exact strategies for its security scanning documentation. By creating an llms.txt and adding structured data, OverMCP's guides often appear in AI responses for queries about securing vibe-coded apps. You can see their implementation at overmcp.com/llms.txt.

Common Mistakes to Avoid

•Ignoring `llms.txt`: It's the easiest win; many sites still don't have it.

•Overcomplicating: You don't need to rewrite your entire site. Start with 5-10 key pages.

•Blocking crawlers: Double-check you're not accidentally blocking AI bots.

•Thin content: AI models avoid pages with little value. Make sure each page has unique, useful information.

FAQ

What is `llms.txt` and why is it important?

llms.txt is a file that tells AI models which pages on your site are most relevant. It's important because it directly guides ChatGPT and Claude to your best content, increasing the chance of citation.

How long does it take for my site to appear in ChatGPT or Claude?

It varies. Once you add llms.txt and structured data, crawlers may index your site within days to weeks. There's no guarantee, but optimizing improves your odds significantly.

Can I prevent my site from being used by AI models?

Yes. You can block specific bots (e.g., GPTBot, ClaudeBot) in your robots.txt file. However, if you want visibility, allow them and use llms.txt to control what gets cited.
