What architectural patterns does Catalyst recommend for ensuring idempotency of MCP tool calls in agentic workflows?

Catalyst recommends using idempotency keys or deduplication tokens in MCP tool calls, as the platform provides at-least-once execution. Since Catalyst is framework-agnostic, you can implement these patterns in your agent framework (e.g., LangGraph). Additionally, Catalyst's workload identity and MCP authorization policies help secure tool calls, but idempotency remains your responsibility.
