Role-Based MCP Servers and Ephemeral Credentials

At 6:30 · chapter starts 5:40

The lesson from the SQL incident translated directly into architectural changes. Datadog built role-based MCP servers — dedicated servers scoped to specific functions like SDRs — that govern exactly what data an AI agent can retrieve based on the user's role. Once that governance layer is in place, employees can use whatever AI tool they prefer. On the engineering side, the challenge was different: how do you let coding agents authenticate to services like GitHub or AWS without exposing static credential files? Datadog contributed to an open-source sandbox that solves this by design — agents simply cannot access credential files in the home directory. Instead, credentials are injected ephemerally at the exact moment an agent needs them, using an existing CLI tool. The agent calls a 'auth GitHub' function, receives a short-lived token, does its work, and the token disappears. No persistent secrets, no exfiltration surface.
