Recurring patterns

The bug types that recur here, drawn from past fixes, not open vulnerabilities.

Denial of Service: Persistent MCP server transport instances on serverless architectures like Vercel led to memory exhaustion and potential service unavailability. Developers must ensure stateless, per-request transport lifecycles with explicit closing procedures on request completion.

Timing Attack: Standard non-constant-time string comparison operators used for sensitive API keys in webhook handlers allowed potential token extraction via timing side-channels. Future integration templates must mandate cryptographic constant-time comparison helper functions.
