Add Rosey to Claude.ai as a custom connector and sign in with one click (OAuth) — no API key needed.
Required: allow Rosey's upload domain
Claude's sandbox blocks uploads by default, so allowlist Rosey's upload domain before fact-checks will work. In Claude, go to Settings → Capabilities → Allow network egress and add this domain: rosey-files.s3.amazonaws.com.
Steps
In Claude.ai, go to Customize, then Connectors.
