Hello there. I’m having intermittent (mostly failing) MCP connection issues across a broad number of AI clients (MCP Inspector, Claude) as well as on our MCP security gateway (barndoor.ai). I tracked it down to OAuth flow taking too long.
- Metadata discover (fast)
- Dynamic client registration (1.5s)
- Auth - granting permission (15.5s+)
- Token request/exchange (12.5s+)
Those last two steps are likely causing the timeouts we’re seeing on AI clients as well as on the gateway.
