Is this page readable for AI search? One command answers it: crawler access, structure, and citability for ChatGPT, Perplexity, Claude, and Google AI — scored 0–100 with concrete findings.

npx geo-tool-check example.com

[Real run against www.geo-tool.com/en: 91/100 Excellent, 2047 words in 231 ms — directAnswers 25/25, structure 14/20, schemaMarkup 15/15, citations 12/15, multimedia 5/5, platformSpecific 20/20; one finding: no table for comparison questions]

Everything runs on your machine. No account, no API key, no telemetry — nothing is ever sent to geo-tool.com. The score is computed by the same engine as the free website audit on geo-tool.com, so the number here matches the number there.

• npm: geo-tool-check — Node 18+, zero runtime dependencies
• MCP registry: io.github.shufflethis/geo-tool-check (stdio server, ships in the package)
• Hosted MCP, no install: https://www.geo-tool.com/mcp (Streamable HTTP) · manifest /.well-known/mcp.json
• Docs: Copy-paste examples · Getting started · CLI reference · GitHub Actions · How scoring works · FAQ · Troubleshooting · Architecture

When to use it

• "Is example.com readable for AI search?" — full 0–100 score with findings
• "Which AI crawlers does my robots.txt block?" — GPTBot, OAI-SearchBot, ClaudeBot, PerplexityBot, Google-Extended and more, each with what blocking it costs you
• "Why doesn't my pricing page show up in ChatGPT answers?" — the findings name what is missing (direct answer, structure, schema, evidence)
• "Is this draft worth citing?" — check_citability scores a text passage with no network request at all
• Gate a deploy — --min-score 70 turns the score into an exit code

Not for measuring whether AI answers actually mention your brand — that is a different measurement: the hosted geo-tool.com workspace checks real ChatGPT, Perplexity, and Gemini answers for your buying-intent questions daily.

Quick start

Use it from an AI agent (MCP)

Almost every MCP client accepts this block (per-client setup, config files to copy):

{  "mcpServers": {    "geo-tool-check": {      "command": "npx",      "args": ["-y", "geo-tool-check", "--mcp"]    }  }}

Clients that speak Streamable HTTP to remote servers can skip the install and use the hosted endpoint instead — same tools, rate-limited, fetches run through geo-tool.com's infrastructure rather than your machine:

claude mcp add --transport http geo-tool https://www.geo-tool.com/mcp

The three tools, identical in both variants:

Claude Code plugin

Install once:

/plugin marketplace add geo-tool-com/geo-tool-check/plugin install geo-tool-check@geo-tool

Then check any page with one command — works immediately, no restart needed:

/geo-tool-check example.com

FAQ

How do I check whether ChatGPT can read my website? npx geo-tool-check example.com. Two things must be true: robots.txt must not block OpenAI's crawlers, and the content must exist in the plain HTML — ChatGPT's crawlers do not execute JavaScript.

Does robots.txt really affect AI visibility? It can end it. Disallow: / for GPTBot means OpenAI's systems never see your content. The checker flags blocked scored crawlers separately from training-only bots, because the consequences differ.

Why does a JavaScript-rendered page score poorly? Because AI crawlers see what curl sees. If content only exists after client-side rendering, models find an empty shell — the low score is the finding. Fixes: SSR, static generation, or prerendering.

Do I need an llms.txt file? Optional and cheap. Google states it does not use it; several AI tools read it. The check detects a real one and ignores SPA catch-all fakes.

Does geo-tool-check upload my content anywhere? No. Every fetch goes from your machine to the target site — never to geo-tool.com. The build fails if a bundle would try.

Honest limits

Node runs no JavaScript — and neither do GPTBot, ClaudeBot, or PerplexityBot. A client-rendered page that scores low here is the finding, not a measurement gap. To compare the crawler's view against the rendered page, use the browser extension.

This checker measures whether a page can be read and cited. Whether AI systems actually mention your brand in real answers is a different measurement: the hosted geo-tool.com workspace checks real AI answers (ChatGPT, Perplexity, Gemini) for your buying-intent questions daily.
