AI SRE Agent Approval Workflow: Identity Forwarding to MCP Servers

Mezmo

Aug 28, 2026

Two engineers can hold the same approve button and still not be allowed to make the same change. The key riding with the approval settles it.

AURA's human in the loop config gates the create_pipeline tool on the Mezmo MCP server and sends each request to a webhook for review. A mock UI stands in for the approval system here, and Mike walks through the payload schema so you can point it at your own.

The first run supplies a made-up key at the approval step. AURA records the approval, the call goes out with that key attached, and the Mezmo MCP server refuses it. The approval was real and the identity behind it was not accepted, which are two separate outcomes.

The second run uses a real key. The call goes through, and what reached the downstream service is Mike's own token rather than a shared agent credential, so the change is attributable to the person who released it.

This run uses one MCP server and one approver. Privileged-role setups, where different reviewers may approve different things, are described at 0:28 and 4:26 and are not demonstrated here.

AURA is built for SRE and platform teams who need agent actions tied to a named person without moving credentials into the agent's config.
