Per-Call Enforcement
Per-call enforcement means that every individual tool invocation by an AI agent is evaluated against access policy at the moment of the call, rather than relying on session-level or configuration-time grants.
Why this matters for AI agents
Session-level access grants allow an agent to invoke any tool it needs for an entire session. Per-call enforcement ensures that each individual invocation is independently verified.
How AgntID relates
AgntID performs per-call enforcement at the tools/call boundary—no tool call bypasses the policy evaluation engine regardless of prior calls in the same session.
The static IAM gap
Session-level access control is the standard model. Once authenticated, all calls in the session proceed. Per-call enforcement adds a layer that session access control cannot provide.

What is per-call enforcement?
Per-call enforcement means that every individual tool invocation by an AI agent is evaluated against access policy at the moment of the call, rather than relying on session-level or configuration-time grants.
How is per-call enforcement different from session-level access?
Session-level access grants allow an agent to invoke any tool for an entire session. Per-call enforcement verifies each individual invocation independently, regardless of prior calls.
How does AgntID implement per-call enforcement?
AgntID performs per-call enforcement at the tools/call boundary. No tool call bypasses the policy evaluation engine regardless of prior calls in the same session.
Secure every agent tool call at execution time.
AgntID gives infrastructure teams scoped, ephemeral access control for AI agents without replacing IAM, MCP servers, tools, or agent frameworks.
