What You Asked Claude to Do

An existing Claude task suddenly stopped working because of a permission issue. After troubleshooting and researching, it appears that a website I use is being lumped into a internal financial-services blocklist. But, it's not a financial services website.

Claude in Chrome silently blocks finance-commerce.com (a Minnesota legal-notices publisher, not a financial services site). No permission prompt ever appears, so the user-side allowlist cannot be used. Please add to exception list or improve classifier

Please do not redirect me to permissions, settings, etc. I've already spent almost two hours diagnosing this, and the only plausable explanation is that "The site may be in Claude's default blocked categories (financial services, banking, investment platforms, cryptocurrency exchanges, adult content, pirated content)."

What Claude Actually Did

I am repeatedly told that the website is hard-blocked.

Expected Behavior

be able to read the publicly available, free portion of the website so that Claude can both navigate AND READ the public notices posted to the domain and sub-urls.

Dolan Finance is still hard-blocked.

This is a real Chrome-permission grant for finance-commerce.com that the Claude-in-Chrome extension is blocking, not a transient state issue

here's nothing I can find that denies (I currently have no permissions, and the extension is setup for all sites.

Got it — that rules out the obvious culprits. Let me search for the most current state of the Claude in Chrome extension's permission model, since this might be behavior that changed recently.

This is the answer. There is a denied list — it's just not yours, and not visible to you.

What's actually happening
Claude in Chrome has a built-in default blocked categories list that you can't see or edit. Per the official Claude Help Center troubleshooting guide:

The site may be in Claude's default blocked categories (financial services, banking, investment platforms, cryptocurrency exchanges, adult content, pirated content).

finance-commerce.com is almost certainly being caught by that filter — its domain literally starts with "finance-" and the homepage contains the words "Finance & Commerce" prominently. The blocklist appears to be classifier-based (matching keywords/categories) rather than a literal domain list, so even though F&C is a legal-notices publisher and not a financial-services site, the domain name is enough to trip the filter.
This matches the pattern in the GitHub bug reports too — Issue #46495 documents the same behavior for a Japanese site, where "Chrome extension site access is already set to 'All sites'" but the extension's internal blocklist still blocks it. The user reported the same thing you're seeing: nothing in your visible permissions, but navigation fails anyway.

Why this just started happening
The §1.x retry logic was added today (2026-04-28) because today's morning run hit this for the first time. Two possibilities for what changed:

Anthropic tightened or expanded the blocklist in a recent extension update. The classifier may have started matching finance-commerce.com where it didn't before.
The blocklist is probabilistic — a classifier that occasionally flips on borderline domains. F&C might be on the edge and is now consistently being caught.

Either way, the §1.x fresh-tab retry won't help if it's the internal blocklist — the retries will keep getting denied because the block is at the domain-classification layer, not the per-site-permission layer.
