AI Video Clipper Fixes Cloudflare KV Race Condition

By PulseAugur Editorial · [1 sources] ·

Katto, an AI video clipping service, encountered an intermittent authentication issue where users attempting to connect Claude over MCP would receive an "Authorization expired" error. The problem stemmed from Cloudflare Workers KV's eventual consistency, causing the callback request to sometimes read a key before it had fully propagated from the deposit request. Initial attempts to mitigate this involved retries and delays, which reduced but did not eliminate the failures. The ultimate fix involved redesigning the OAuth flow to eliminate the need for a cross-request read, completing the grant within a single request. AI
