Agent authorisation

Agent authorisation at the policy boundary

Agent authorisation belongs at a policy boundary, not buried in prompts or post-hoc reviews. AffixIO evaluates policy and returns ML-DSA-65 signed allow or deny before consequential actions run.

Definition

An agent authorisation policy boundary is the verify step that must pass before an agent may execute a consequential action.

Field note. Policy enforced only inside the agent process disappears when the model ignores guardrails. Move authorisation outside the runtime.

Put the gate in one place

Introduce AffixIO verify as the policy boundary for tools, payments, and sensitive retrieval. Downstream systems trust the signed outcome.

Agent authorisation product pages describe capabilities and integration. MCP and payment sectors show concrete placements.

Ownership model

Security defines policy classes. Product maps actions to classes. Engineering wires verify. Audit retains Merkle refs. That split keeps the boundary honest.

Deny must be a first-class path with human escalation where needed.

Operational detail for agent policy authorisation

For agent policy authorisation, provision sandbox circuits that mirror production predicates before you expose live agent traffic. Capture sample allow and deny payloads for regression tests.

Keep identity and rich attributes with the issuer. Verifiers receive outcomes and Merkle metadata only. Sync audit refs to your SIEM or order store after the gate returns.

Tool-call risk

Authorisation smeared across the stack

When policy lives in prompts, SDK wrappers, and human review queues, no single place owns allow or deny.

No single gate

Different tools enforce different informal rules.

Post-hoc only

Reviews happen after damage.

Unclear ownership

Platform, security, and product disagree on who decides.

Deny-code mapping

Agent authorisation at the policy boundary, not in the runtime

Agent runtimes should not decide their own authorisation scope. Wire policy evaluation to AffixIO issue at satisfaction and verify at the boundary before side effects.

  1. Declare the boundary

    Which actions require verify.

  2. Map policies

    Agent classes to scopes.

  3. Wire AffixIO verify

    Pre-exec on those actions.

  4. Operate deny

    Escalation and audit.

Pre-flight checks

Readiness checks for agent policy authorisation

  • Publish the list of gated actions.
  • Remove prompt-only authorisation as sole control.
  • Assign owners for policy, wiring, and audit.
  • Test deny escalation.
  • Read /agent-authorisation/.

Questions on agent policy authorisation

Can policy stay in the LLM?

Not as the sole control. Use AffixIO for signed decisions.

One boundary or many?

One logical boundary, possibly multiple verify call sites.

Payments included?

Yes. Payment permission is a policy boundary action.
