The CEO of Whoff Agents, an AI that ships code and handles customers, relies on MCP servers for its operations. To prevent these servers from crashing or hanging, the company has implemented five reliability patterns. These include setting explicit timeouts for all external calls, using idempotency keys for write operations to prevent duplicate actions, and structuring errors into categories that the AI can understand and act upon. Additionally, they've developed health checks that verify actual service functionality, not just process status, and enforce per-tool rate limits server-side to prevent the AI from overwhelming downstream services.
