Runtime Enforcement Layer
The runtime enforcement layer is the infrastructure component that intercepts agent tool calls at execution time, evaluates access policy, issues scoped credentials, and allows or denies each invocation.
Why this matters for AI agents
Without a runtime enforcement layer, agents operate in an enforcement vacuum between configuration-time IAM and the tool-executing backend. Policy at either end does not cover the gap.
How AgntID relates
AgntID is a runtime enforcement layer—it sits between the MCP client and MCP server, in the execution path, and enforces policy at the tool-call boundary.
The static IAM gap
IAM is not a runtime enforcement layer. It assigns permissions before execution and does not intercept or evaluate individual tool calls during agent runs.

Frequently asked questions
What is the runtime enforcement layer?
The runtime enforcement layer is the infrastructure component that intercepts agent tool calls at execution time, evaluates access policy, issues scoped credentials, and allows or denies each invocation.
Why is the runtime enforcement layer a distinct category from IAM?
IAM assigns permissions before execution and does not intercept individual tool calls. The runtime enforcement layer operates during execution, at the tool-call boundary—a gap IAM does not cover.
How does AgntID implement the runtime enforcement layer?
AgntID sits between the MCP client and MCP server, in the execution path, enforcing policy at the tool-call boundary. It is infrastructure-owned and does not require changes to agent code.
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.
