Prompt Injection
Prompt injection is an attack where malicious content embedded in an agent's input or context manipulates the agent to take actions outside its intended task—including invoking unauthorized tools.
Why this matters for AI agents
Prompt injection can turn a benign agent into an attacker's proxy. Without runtime enforcement, a successful injection gives the attacker access to every tool the agent can reach.
How AgntID relates
AgntID limits the blast radius of prompt injection attacks by enforcing per-task, per-tool policy—even if an injected prompt causes the agent to attempt an unauthorized call, the enforcement layer blocks it.
The static IAM gap
IAM cannot detect prompt injection. The agent's tool calls appear legitimate at the permission level even when they are driven by malicious injected instructions.

Frequently asked questions
What is prompt injection for AI agents?
Prompt injection is an attack where malicious content embedded in an agent's input or context manipulates the agent to take actions outside its intended task—including invoking unauthorized tools.
Why is prompt injection so dangerous for agents?
Prompt injection can turn a benign agent into an attacker's proxy. Without runtime enforcement, a successful injection gives the attacker access to every tool the agent can reach.
How does AgntID limit prompt injection risk?
AgntID limits the blast radius of prompt injection. Even if an injected prompt causes the agent to attempt an unauthorized tool call, the per-task, per-tool enforcement layer blocks it.
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.
