## Updates from Apify
### 2026-05-06 20:08 UTC: identified
OAuth sign-in to mcp.apify.com from clients using CIMD with loopback redirects (currently Claude Code) is failing due to a regression.
Existing connections and other clients (claude.ai, Cursor, Codex) are unaffected (the later use DCR).
We are sorry for the inconvenience and working on a fix.

### 2026-05-07 08:27 UTC: resolved
We have implemented a fix for the OAuth flow, and the connections are now working normally.
