Secure delegation is a control-plane problem, not a prompt-writing problem. Give each agent a verifiable identity, bind each task’s authority to its principal and purpose, and have trusted infrastructure check every consequential action before execution. A delegated agent should receive no more authority than its parent grant allows; short-lived credentials, revocation, audit logs, and deterministic human approval for high-impact actions complete the design.
What secure delegation must prove
When an agent asks another agent to do work, the system must be able to answer four questions without relying on either model’s claims: who initiated the work, which agent is acting, what authority applies to this task, and who checks that authority before the requested action takes effect.

A prompt can describe a boundary, but it cannot enforce one. The model may misunderstand or ignore an instruction, or untrusted content may manipulate it. OWASP’s AI Security and Privacy Guide explicitly cautions against implementing authorization in instructions the model can reason around. Put authorization policy and enforcement in trusted infrastructure outside the agent’s reasoning context.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Identity and authorization solve different problems. Identity establishes which actor made a request; it does not establish that the action is intended, safe, or permitted in context. A valid tool-call schema likewise shows that arguments have an expected shape, not that the call is authorized. A permitted operation can still produce an unwanted business result, so security controls need policy checks as well as operational safeguards.

Build the control plane around identities and boundaries
Map the people or services that initiate work, orchestrators, delegated agents, tools, data stores, policy services, credential issuers, and external trust domains. Mark where identities cross services or tenants and where data or instructions enter from outside the system. Assign each managed agent or workload a distinct, verifiable identity with an accountable owner; shared identities make it harder to attribute actions to the actor that performed them.
Keep the model in the role of requester: it proposes work and actions. A trusted execution boundary—such as a tool proxy, gateway, or service endpoint—verifies the caller, obtains or evaluates authorization context, applies policy, and permits or denies execution. A policy decision point evaluates the request; a policy enforcement point makes the decision effective. Do not give the agent a way to bypass that boundary by calling a more privileged tool directly.
NIST’s NCCoE concept paper treats agent identity, authorization, delegation, accountability, logging, and data-flow provenance as connected design concerns. It is a project direction, not a finalized, universal agent-delegation standard. Its initial focus is enterprise use cases with greater organizational control and visibility; it places agents from untrusted external sources outside that initial effort.
Bind every task to an explicit, attenuating grant
Represent authorization as a machine-verifiable grant or trusted server-side context. Do not rely on a natural-language message such as “the user approved this” as proof of authority. The context must let the enforcement layer distinguish the original principal, each agent in the chain, and the precise work being authorized.
| Grant field | What it constrains |
|---|---|
| Initiating principal | The human or service on whose behalf the task began. |
| Verified caller and delegate | The agent making the request and, for a handoff, the downstream agent permitted to receive the task. |
| Purpose or task | The work the grant is for; unrelated requests should not inherit it. |
| Audience | The service or recipient allowed to accept the grant. |
| Resources and operations | The specific data or systems and allowed actions, such as reading a named record rather than writing across a database. |
| Argument and context constraints | Relevant limits on inputs, data classification, trust context, or other action parameters. |
| Time window and revocation state | When the grant is valid and how operators can invalidate it. |
| Correlation or session identifier | The workflow context used to trace related actions and delegation events. |
These fields are a design recommendation, not a claim that one token format standardizes them. A grant may be carried as a protected authorization artifact or maintained as server-side context. Whichever approach is used, integrity-protect the context and check it at the service that will perform the action.
Delegation must attenuate authority: a downstream agent receives only the task-specific subset of permissions available to its parent, never a broader grant by default. If the task, resource, operation, or trust context changes, obtain a new authorization decision. Do not treat access given to the orchestrator as authority that every subagent can inherit automatically.
Authorize each consequential action at execution time
At the tool or service boundary, evaluate the verified actor, initiating principal, delegation chain, task, audience, resource, operation, arguments, grant lifetime, and relevant trust context. Deny by default if identity cannot be verified, policy cannot be evaluated, or the request falls outside the grant. Keep policy logic and signing secrets out of agent prompts and memory.
Recheck authorization for each privileged action, not just when a workflow starts. Reauthorize when an operation shifts from read to write, adds resources, crosses a trust boundary, relies on new untrusted input, or is handed to another agent. OWASP AISVS calls out fine-grained runtime authorization, integrity-protected scope-limited delegation tokens, and explicit authorization policy for inter-agent task delegation.

Expose only the tools needed for the task. Validate tool names, argument types, and input constraints against strict schemas and allowlists, then separately authorize the actual request in context. Treat retrieved documents, tool metadata, inter-agent messages, and arguments as untrusted data; none can confer new authority merely by containing an instruction. Microsoft’s guidance on securing autonomous agentic AI systems also emphasizes explicit action schemas, isolated permissions, logging, filtering, and runtime guardrails.
Use credentials that limit exposure
Prefer short-lived, narrow-scope credentials with an audience restriction over long-lived bearer credentials that can be reused wherever accepted. Verify credentials at the receiving boundary, protect signing material in managed key or secret systems, rotate keys, and define how operators revoke grants and respond to suspected compromise. Do not place secrets in prompts, agent memory, source files, or logs.
NISTIR 8587, published September 15, 2026, addresses token protection, key management, verification, and lifecycle controls in SSO, federation, and API scenarios. NIST’s 2026 article on agent identity discusses dynamic, tightly scoped, audience-restricted credentials, as well as sender-constraining approaches and authorization-context propagation. Rich Authorization Requests and transaction-token work are discussed as directions for greater granularity or for preserving and attenuating context across call chains; check the current maturity and implementation details of any profile before making it a dependency.

Short lifetimes and narrow scope reduce the time and reach available to a stolen credential, but do not eliminate misuse of an authorized tool, compromised workloads, or policy mistakes. Modern protocols also cannot by themselves fix broad entitlements or permission creep. Credential controls must work alongside least-privilege policy, action-level checks, and an operational revocation path.

Make human approval a deterministic control
Define risk tiers in policy or orchestrator logic, not through a request for the model to exercise judgment. Require human approval or a policy-defined step-up for privilege expansion and actions such as sensitive data export, destructive writes, external communications, financial or legal commitments, and irreversible operations.
Bind an approval to the proposed action and its relevant context: the actor, task, target, operation, and material parameters. If those details change before execution, the old approval should no longer authorize the changed action. Record the approval and enforce it at the same trusted boundary that checks the grant. OWASP recommends human approval for high-privilege or irreversible actions; Microsoft recommends deterministic review through orchestrator logic.
Log enough to attribute, investigate, and revoke
For each request and outcome, record the verified actor, initiating principal, parent delegator, task or purpose, grant identifier, requested and effective permissions, target resource, operation, policy version and decision, approval event, result, and relevant input provenance. Link related records with a workflow or correlation identifier so an investigator can trace a delegation chain and identify where effective permissions changed.
Recommended Free Tools
Protect logs against tampering and exclude raw credentials and signing secrets. Ensure operators can find and revoke grants or credentials promptly, including those issued to downstream agents. NIST’s concept paper identifies logging and transparency tied to non-human identity, along with prompt and input-source provenance, as areas of interest.

Compare implementation patterns by control, not protocol label
NIST’s NCCoE concept paper considers several technology families. They address different parts of the problem; none is presented there as a complete, endorsed agent-specific delegation stack.
| Technology family | Role described in the concept paper | What to evaluate for delegation |
|---|---|---|
| OAuth 2.0 and extensions | Authorization and related mechanisms. | How the implementation scopes and audiences grants, carries context across handoffs, and handles expiry and revocation. |
| OpenID Connect (OIDC) | Authentication and identity information. | How verified identity is linked to the principal, workload, and authorization decision; identity alone is not task permission. |
| SPIFFE/SPIRE | Workload identity. | Whether it fits workload identification and trust across the services in the deployment; determine how authorization and delegation are supplied alongside it. |
| SCIM | Identity lifecycle management. | How identities and lifecycle events fit existing provisioning and deprovisioning processes. |
| NGAC | Fine-grained access control and delegation. | Whether its policy and delegation model fits the required resources, operations, and operational environment. |
| MCP identity mechanisms | The concept paper discusses MCP’s use of OAuth/OIDC-related mechanisms. | Verify the relevant protocol profile, audience and scope behavior, and enforcement responsibilities for the specific implementation. |
OWASP references policy-as-code options such as OPA/Rego and Cedar for externally enforced, auditable policy. Compare policy engines by integration points, evaluation behavior, language, operational model, and auditability; neither is a universal requirement. Across the stack, assess identity granularity, preservation of the principal and delegation chain, attenuation, permission granularity, credential lifetime and sender constraints, per-action enforcement, approval binding, revocation, auditability, and fit with existing identity providers and tools.
Test the ways delegation can fail
Exercise negative and recovery paths before relying on the workflow. In particular, test whether the enforcement boundary denies rather than guessing when a credential, identity, or policy decision is missing or invalid.

- Expired, revoked, replayed, tampered, or wrong-audience credentials.
- Cross-tenant or cross-task reuse, delegation loops, and attempts by a child agent to obtain more authority than its parent grant.
- Unexpected resources or operations, including a read-to-write change or additional arguments outside the approved constraints.
- Prompt-injection attempts in retrieved content, tool output, inter-agent messages, and other untrusted inputs.
- Policy service or identity-provider outage, approval expiry, and attempted execution after a grant has been revoked.
For each case, verify not only that the request is blocked but that the denial is attributable in logs and the relevant grant or credential can be invalidated. OWASP’s agentic guidance highlights identity sharing, forged personas, delegated abuse, and privilege escalation as threat patterns to account for.
A practical implementation sequence
- Inventory the actors and boundaries. Map principals, agent workloads, tools, data, identity and policy services, owners, and trust crossings; assign agents distinct identities.
- Define grant semantics. Specify the principal, caller and delegate, purpose, audience, resources, operations, relevant argument constraints, validity window, correlation context, and revocation behavior.
- Put enforcement at the execution boundary. Route consequential tool calls through a trusted policy decision and enforcement path. Keep secrets and policy authority outside model-controlled context, and deny when checks fail.
- Implement attenuation and reauthorization. Ensure each child grant is a subset of its parent and require fresh decisions when scope or context changes and before privileged actions.
- Set credential and approval lifecycles. Implement narrow, time-limited credentials, key protection and rotation, revocation procedures, risk tiers, and approvals bound to the action being authorized.
- Instrument and test. Record the delegation chain and decisions, then run the failure cases above—including outages, revocation, and untrusted input—before enabling the workflow in production.
Limits to keep visible
Authorization controls determine whether an action is allowed under the configured policy; they cannot guarantee that a permitted action is wise or that the policy reflects business intent. Review consequential workflows for outcome risk as well as access risk. Agent identity offerings and protocols also change quickly, so evaluate a specific implementation’s current behavior and operational fit rather than treating a product label or protocol name as proof of secure delegation.
