How can automated workflows safely call MCP servers?

Automated workflows can safely call MCP servers when each call is tied to a known workload identity, an approved policy, durable execution state, and an audit record. The workflow should not simply pass a powerful token to every step. Instead, it should enforce least-privilege permissions, preserve context about why the tool call is happening, and recover safely if the call fails. Durable execution helps keep progress and avoid duplicate side effects, while identity and policy define what the workflow is allowed to do. Diagrid Catalyst brings these concerns together for agent and MCP workflows.
