Runtime Agent Gateway

Agent → Gateway → authenticate → classify → policy → approve/deny → execute → record outcome.

Priority: P0
Phase: MVP
Primary owner: Platform / Security Eng
Status: Blueprint

Objective

The runtime gateway turns Agent Trust Cloud from a dashboard into control infrastructure. It intercepts or brokers sensitive agent actions, enriches them with identity and risk context, evaluates policy, optionally requests approval, then forwards or blocks the action.

What to build

HTTP/API proxy mode for standard web APIs.
SDK/interceptor mode for application-native integrations.
MCP gateway mode for tool discovery and invocation.
Brokered connector mode for SaaS/ERP systems where direct proxying is impractical.
Optional regional/customer-managed gateways for sensitive environments.

Implementation decisions

Preserve request semantics and minimize latency; never silently mutate business data except explicit redaction/transform policies.
Use correlation IDs across agent request, policy decision, approval and downstream result.
Fail closed for explicitly protected critical actions; configurable fail behavior for low-risk telemetry-only paths.
Buffer telemetry asynchronously so logging failures do not create cascading outages.

Definition of done

Gateway can protect one real API end-to-end with identity, policy, approval and evidence.
Policy bundles can continue operating during temporary control-plane outage.
High-risk action latency remains acceptable for enterprise workflows.
