TL;DR: APISIX can govern the edge of an AI request, but it cannot by itself govern the full agent decision path once tools and delegated actions enter the picture, according to Archestra. Agent workflows need their own identity, authorization and audit controls before they reach production.
Editorial analysis by NHI Mgmt Group, based on content published by Archestra: “Apache APISIX AI Gateway + Archestra: Open Source on Top of Open Source”.
Key questions
Q: Why do gateway logs fail to explain unsafe agent behaviour?
A: Gateway logs show that a request arrived and was forwarded, but they do not capture the agent’s internal choice of tools, the identity context that shaped the choice, or the influence of intermediate model output.
Q: When should teams split AI gateway and agent governance into separate layers?
A: Teams should split them when the system does more than proxy prompts and begins making tool decisions, calling MCP servers or acting on behalf of a user.
A: When governance sits only inside the application, controls are easier to bypass, audit trails fragment, and policy enforcement becomes inconsistent across agents and tools.
Practitioner guidance
- Separate gateway policy from agent governance Use the edge gateway for OIDC, rate limits, traffic shaping and provider fan-out, but move tool authorization, delegated action approval and identity-bound audit into the agent layer.
- Bind tool access to the calling identity Map each human or workload identity to the exact tools, MCP servers and delegated scopes it may use, rather than assuming a validated request is enough.
- Log decision context, not only request metadata Capture the selected tool, resolved identity, upstream model response and resulting action so review can reconstruct why the agent acted.
Bottom line: APISIX can govern the edge of an AI request, but it cannot by itself govern the full agent decision path once tools and delegated actions enter the picture.

Gateway controls and agent controls solve different problems: APISIX-style edge enforcement handles transport, request routing and coarse policy, but it does not govern the full agent decision path. Once an AI system begins choosing tools, the security question changes from request acceptance to delegated action control. That distinction matters because identity governance cannot stop at the edge of the conversation.
A few things that frame the scale:
- AI-related credential leaks surged 81.5% year-over-year in 2025, with the surrounding AI infrastructure leaking 5x faster than core LLM providers, according to the State of Secrets Sprawl 2026.
- 52% of respondents see AI security decision-making power shifting toward platform and infrastructure teams rather than the executive suite, according to the 2026 Infrastructure Identity Survey.
A question worth separating out:
Q: What is the difference between request authorization and delegated tool authorization?
A: Request authorization decides whether traffic may enter the system. Delegated tool authorization decides whether a specific identity may perform a specific action through an agent after the request has already been accepted. The first is a perimeter control; the second is an action control, and both are needed when agents operate on behalf of users.
