Before you install
- Basic checks: 1 of 1 passed
- Runs on your computer with your user’s permissions (files, network, apps).
- You fill in yourself:
CRAWLBIT_BASE_URL
You need
- npmNode.js installed (for the npx command)
Which app do you use?
Pick your app above. We remember it, so next time the button says “Install in …”.
Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

}
}Run this in your terminal
claude mcp add crawlbit --env CRAWLBIT_BASE_URL=your-value -- npx -y crawlbit-mcpFill in the empty values before running it.
Or copy the settings yourself
Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

"env": {
"CRAWLBIT_BASE_URL": "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.
Or copy the settings yourself

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Common questions
Is Crawlbit 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?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).
Is it still maintained?
The GitHub repo last changed –, and the latest version (1.0.1) reached the registry 3 months ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.
What can I use instead?

CrawlBit MCP
Four free tools that answer one question: can AI engines find, read and recognise a website?
No account. No API key. No signup. Nothing here runs a language model, so nothing here costs you or us anything.
"Can ChatGPT read stripe.com?""Why does AI never mention my store?" "Where is my brand missing outside my own site?"
Ask in plain language. Your AI client picks the right tool.
Install
Requires Node.js 18+.
Claude Code
claude mcp add crawlbit -- npx -y crawlbit-mcpClaude Desktop
Add to claude_desktop_config.json:
{"mcpServers": { "crawlbit": { "command": "npx", "args": ["-y", "crawlbit-mcp"] } } }
Cursor
Add to .cursor/mcp.json:
{"mcpServers": { "crawlbit": { "command": "npx", "args": ["-y", "crawlbit-mcp"] } } }
Restart your client. Four tools appear.
The four tools
| Tool | What it answers |
|---|---|
crawlbit_crawler_watch | Can GPTBot, OAI-SearchBot, ClaudeBot, PerplexityBot and Google-Extended read this site? |
crawlbit_entity_check | Does this brand read as a clear entity AI can recognise? |
crawlbit_offpage_gaps | Where is this brand missing outside its own website? |
crawlbit_shopping | Can AI shopping agents understand and recommend these products? |
Try these
Check whether AI crawlers can read example.comDoes example.com read as a clear brand entity to AI? Where is example.com missing off-page, and which gap should we close first? Compare example.com and competitor.com on AI crawler access
The tools compose. A useful sequence is: crawler access first (a blocked crawler makes everything else pointless), then the entity check, then the off-page gaps.
What this does NOT do
Written plainly, because an SEO tool that overstates itself is worse than no tool.
- It does not test whether AI actually cites a brand. That means running real buyer questions against ChatGPT, Perplexity and Claude, reading the answers, and reporting who gets named instead of you. It costs real money per run and is not part of this free surface. These four tools measure the conditions that make a citation possible, which is a smaller claim.
- `crawler_watch` reads `robots.txt` only. It cannot see blocking done at the CDN, firewall or rate-limit layer. A site can pass here and still refuse the crawler in practice.
- `entity_check` reads what the site publishes about itself. It says nothing about the brand's reputation across the rest of the web.
- `shopping` inspects published structured data. It cannot see a merchant feed submitted privately to a platform.
If a site scores well on all four and still is not cited, the answer is almost always the same and it is not technical: too few third-party pages mention it. These tools will tell you that honestly rather than sell you a fix that does not exist.
Why only four tools
CrawlBit also runs a full technical audit and generates llms.txt. Both use a language model, so both cost money per run, and neither is exposed here.
That is a deliberate line rather than a teaser. A free tool whose bill grows with its popularity gets rate-limited, degraded or withdrawn the moment it succeeds, and the people who installed it are the ones who pay for that. Everything in this server costs nothing to run, so nothing here has to be taken back later. The audit and the llms.txt generator live at crawlbit.app if you want them.
Rate limit
The API rate-limits per IP. Normal conversational use does not come close, and the server runs on your machine, so the budget is yours rather than shared. If you do hit it, you get a plain sentence rather than a stack trace.
Configuration
| Variable | Default | Purpose |
|---|---|---|
CRAWLBIT_BASE_URL | https://www.crawlbit.app | Point the server at another instance |
Privacy
The server runs locally and stores nothing. The only data leaving your machine is the URL you ask about, sent to the CrawlBit API to be analysed. There is no account, so there is nothing to tie a request to a person.
About
Built by CrawlBit, which measures AI visibility and does the off-page work that earns citations. The free tools here are the measurement half. The paid work is the other half, and you are not required to look at it to use this.
