Agent routing for AI coding assistants: what changes for IAM teams?

TL;DR: AI coding assistants in VS Code can be used without per-provider tickets or scattered API secrets, according to Tetrate, by centralising provider grants, model allow-lists, budgets, and project-scoped keys. The governance problem is no longer access enablement itself, but how to keep model use, spend, and credential scope bounded as AI tooling spreads across the editor and terminal.

Key questions

Q: What breaks when AI model access is controlled by the provider instead of the customer?

A: The customer loses continuity when the provider or a regulator revokes access, even if the customer has done nothing wrong.

Q: Why do project-scoped AI credentials reduce risk in developer tools?

A: They reduce risk because the credential is bound to a specific project, not to a developer’s personal provider relationship.

Q: What do security teams get wrong about AI cost control?

A: They often treat cost as a finance-only issue and overlook the identity layer that drives usage.

Practitioner guidance

• Define project-level AI entitlement boundaries Scope approved providers, models, and MCP access by project rather than by individual developer preference, so requests are evaluated against one governed boundary.
• Treat inference keys as governed credentials Issue one project-scoped inference key per approved workflow and track last use, creation date, and masked display so abandoned credentials can be identified and revoked.
• Separate budget policy from emergency cutoff controls Use team or key budgets for spend ceilings, then pair them with an immediate inline control when requests must stop without waiting for usage rollups.

Bottom line: AI coding assistant access becomes much easier to govern when providers, models, budgets, and keys are tied to a project boundary instead of being managed as separate tickets and shared secrets.
