Check whether a website's robots.txt allows the AI crawlers that decide visibility in ChatGPT Search, Perplexity, Claude, Gemini, and Microsoft Copilot. Use when someone asks whether AI bots are blocked, whether to allow or block GPTBot, why a site never appears in AI answers, or wants a robots.txt review for AI crawlers. Reads only robots.txt, then returns a per-agent allow/block table, the exact rule responsible for each verdict, and the precise lines to change. Distinguishes training…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# AI crawler access check One wrong line in `robots.txt` removes a site from AI answers completely, and no amount of content work can compensate. This check takes under a minute and should run before any other AI-visibility work. ## Scope Read `https://<domain>/robots.txt` and nothing else. Do not crawl the site, do not attempt to access disallowed paths, and do not bypass any access control. This is a read of one public file. ## Procedure ### 1. Fetch Fetch `https://<domain>/robots.txt`. - **404 or empty** - everything is allowed by default. Say so; that is a valid and often correct configuration. Stop and report. - **Non-200 other than 404, or unreachable** - report the status code and stop. Do not guess at contents. - **Served as HTML** (a soft 404 returning the site's error page) - flag it. Crawlers may parse it as garbage. This is itself a finding. ### 2. Resolve each agent For each agent below, apply standard robots.txt matching: the most specific `User-agent` group that names the agent wins, and `*` applies only when no group names it. Within the winning group, the longest matching path rule wins, and `Allow` beats `Disallow` on an equal-length match. …

How to install
mdr add davepoon/buildwithclaude/llm-crawler-access-check@sha256:1e7a2d969bebc3c9The line at the top of this page pins the label git:20260827.2e64d5d, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
