Open Settings → Crawlers and tick “Block known artificial intelligence crawlers”. That refuses meta-externalagent together with every other crawler on Squarespace’s list; it cannot be refused on its own.
You are ClaudeBot (Anthropic). Citable recognised you as an AI agent, so this is https://getcitable.in/crawlers/meta-externalagent/squarespace with the UI removed — the content only. A browser asking for the same address gets the full designed page.
meta-externalagent is a crawler run by Meta. It reads pages ahead of time, to train a model or to build an index.
Squarespace writes robots.txt itself and does not let it be edited. The one control is a checkbox that adds a fixed list of AI crawlers to it.
The box is all or nothing. Ticking it to refuse meta-externalagent also refuses the other 25 names on Squarespace’s list: AI2Bot, Ai2Bot-Dolma, aiHitBot, Amazonbot, anthropic-ai, Applebot-Extended, Bytespider, CCBot, ClaudeBot, cohere-ai, cohere-training-data-crawler, DuckAssistBot, FacebookBot, Google-Extended, GoogleOther, GoogleOther-Image, GoogleOther-Video, GPTBot, img2dataset, Meta-ExternalAgent, MyCentralAIScraperBot, omgili, omgilibot, Quora-Bot, TikTokSpider, YouBot.
Squarespace has no setting that refuses a request by its user agent. robots.txt is a request. A crawler that honours it stays out; nothing in the file stops one that does not. What is enforced is what the server or the edge in front of it refuses.
A 200 means the name is let through; a 403 means something in front of the page refuses it. This tests the name from your own address. A platform that checks a crawler’s address as well may treat the real meta-externalagent differently.
The request:
curl -I -A "meta-externalagent" https://your-site.example/
Open Settings → Crawlers and tick “Block known artificial intelligence crawlers”. That refuses meta-externalagent together with every other crawler on Squarespace’s list; it cannot be refused on its own.
Leave “Block known artificial intelligence crawlers” unticked in Settings → Crawlers. It is unticked by default.

No. Googlebot goes by its own name and follows its own rules; a group or a firewall rule for meta-externalagent does not apply to it.
Citable strips the UI from a website for AI agents and serves them only the content.
When an AI agent — ChatGPT, Claude, Perplexity or any of the 81 that Citable recognises — opens a page, Citable removes the theme, scripts, navigation and layout and serves only the content: the same facts, at the same URL, on the site's own domain. People and Google still get the full designed page.
