Keep authentication, authorization and validation in deterministic systems outside the model, then add controls for untrusted content, tool permissions, action consequences and independent approval. A secure API is still essential, but it cannot by itself prevent an agent from being manipulated into making an authorized yet harmful call.
What changes when a model chooses the actions?
In a conventional API interaction, an application or client sends a request to an endpoint. Security focuses on the caller, the request and the API lifecycle. An agent adds a decision-to-action path: a model may select a tool, derive its parameters and decide what to do next based on prompts, retrieved material and earlier tool results.
That material is not necessarily trustworthy. A web page, document, email, tool description or peer-agent message can contain hostile instructions as well as ordinary data. The model may interpret those instructions as relevant to its goal. OWASP’s AI Agent Security Cheat Sheet describes agents as systems that can reason, plan, use tools, maintain memory and take actions; NIST’s August 2025 tool-use report similarly describes models manipulating tools to act beyond text output.
The security boundary therefore has to cover not just whether a request is valid, but whether the agent should have been able to select that action, with those privileges, in that context.

How do the security priorities compare?
| Security axis | Traditional API security | Additional AI agent security |
|---|---|---|
| Decision authority | A client or application submits a request; protect the endpoint and request lifecycle. | A model may choose a tool, supply its parameters and sequence actions using prompts and retrieved content. |
| Input trust | Validate and handle API inputs using application security controls. | Consider model-visible pages, documents, emails, tool descriptions and outputs as possible adversarial instructions or data. |
| Authorization | Authenticate the caller, authorize the operation and enforce API policy. | Also constrain available tools, per-operation capabilities, user context and delegation. A prompt is not an authorization boundary. |
| Blast radius | Limit API permissions and protect the endpoint. | Account for chained calls, memory or persistent state, downstream effects, reversibility and impact. |
| Oversight | Apply runtime controls and log API calls. | For high-impact operations, add independent approval and connect agent decisions to tool calls and downstream effects in monitoring. |
| Evaluation | Test API lifecycle controls and runtime defenses. | Also test indirect prompt injection, goal hijacking, unauthorized tool use and unsafe action chains. |
This comparison synthesizes NIST API guidance with NIST and OWASP agent guidance; it is not a quotation from a single standard.
Why are API controls not enough?
An API can correctly authenticate an agent and accept a well-formed request while the action is still unsafe. The request may have been selected after the model followed hostile content, misunderstood the user’s goal or chained several individually permitted operations into a harmful outcome. Valid credentials and valid parameters do not establish that the model’s decision was appropriate.
OWASP’s LLM06:2025 Excessive Agency identifies excessive functionality, permissions and autonomy as root causes. Model error and direct or indirect prompt injection can trigger damaging actions. This makes excessive agency a system-design problem: the model should not be given capabilities or discretion that the surrounding application cannot safely bound.
Which controls should surround an agent?
Limit what it can do
- Inventory every reachable API and tool, including extensions, computer-use capabilities, code execution and sub-agents. Describe each capability concretely rather than relying on a broad label such as “assistant.”
- Remove unused tools and split broad functions into narrow operations. Reading email should not implicitly grant the ability to send or delete it.
- Separate read and write access. Use least-privilege, scoped identities in the user’s context, and enforce authorization in the downstream system rather than relying on model instructions.
Mediate every action
Put deterministic policy enforcement between the model and each downstream operation. Check every request against the actor, requested operation, resource, user context and applicable policy; do not assume that a previous check covers the next call in a sequence. Treat user prompts, retrieved content, tool results and peer-agent messages as possible injection paths. Instructions to the model can help express intent, but they are not access controls.
Gate consequential operations
Use independent approval for financial, destructive, administrative or externally visible actions. The approval should identify the actual operation and its effects, not merely ask whether the user approves a vague plan. OWASP cautions that a simple approval prompt may not be sufficient for high-impact actions; design the review around the risk and reversibility of the operation.
Observe and test the action path
Monitor agent decisions, tool invocations and downstream activity in a way that lets investigators connect them. Rate limits can help limit damage, but monitoring and rate limiting are not substitutes for preventing excessive agency. Test adversarial cases, including indirect injection and unsafe action chains, as models, tools and retrieval sources change.

NIST’s August 5, 2025 report, updated August 7, recommends assessing tool functionality, access patterns, risk and reversibility, reliability, modality, monitoring and autonomy. Those dimensions help turn an inventory into decisions about what an agent can safely do.
- Capability: What can the tool change or expose? Distinguish reading from writing, and narrow operations from broad administrative functions.
- Access pattern: Which identity, resources and environment does it use? Separate user-scoped access from broader service privileges, and distinguish trusted from untrusted environments.
- Consequence and reversibility: Could an action expose information, affect another person or cause a difficult-to-reverse change? Higher-impact operations warrant tighter controls and independent review.
- Autonomy and observability: Can the tool act repeatedly or continue without intervention, and can the resulting activity be monitored? Greater autonomy needs correspondingly strong limits and visibility.
This classification is more useful than treating every tool call as equivalent: a read-only lookup and a destructive write should not inherit the same authority merely because both are exposed through an API.

What standards and guidance should teams use?
NIST SP 800-228-upd1, published March 13, 2026, provides a current reference for API risk analysis and basic and advanced protections at pre-runtime and runtime stages. Its update adds appendices on API risk categories and lifecycle-stage controls. Use it to strengthen the APIs an agent reaches, then add agent-specific controls for tool selection, untrusted inputs and consequential action approval.
For agent design, OWASP’s AI Agent Security Cheat Sheet, LLM06:2025 Excessive Agency and Securing Agentic Applications Guide 1.0 provide architecture and mitigation guidance. NIST’s AI Agent Standards Initiative, updated August 14, 2026, describes voluntary, industry-led guidelines, interoperable protocols and research into agent identity, authentication and security evaluation. It is an evolving initiative, not a finished comprehensive standard.
Apply these references to the actual deployment: its tools, identities, data, downstream systems and consequences determine the controls needed.
