Compare AI agent authorization approaches

Most guardrails detect bad outputs. APort prevents bad actions with synchronous policy decisions before every tool call. Use this lens to compare approaches fairly.

Two teams can solve agent permissions with different goals: on-chain identity, product-resource access control, output filtering, sandbox containment, evals, or enterprise-grade pre-action policy. The table below summarizes how OAP and APort position against common alternatives without claiming others have no merit.

When you need delegated authorization at the tool boundary with signed decisions and kill switches, compare hooks and audit models, not slide decks.

Dimension	OAP / APort	Prompts & alignment only	Sandbox / container only	Agent Passport System
Pre-action enforcementIs every sensitive action gated before execution?	Yes — `before_tool_call` / shell hooks; model cannot bypass the platform layer.	No deterministic gate — relies on the model following instructions.	Contains blast radius; does not prove the action was authorized under policy.	Signed ActionIntent → PolicyDecision flow; depends on agent participation in the chain.

Pre-action enforcement

Is every sensitive action gated before execution?

OAP / APort: Yes — `before_tool_call` / shell hooks; model cannot bypass the platform layer.
Prompts & alignment only: No deterministic gate — relies on the model following instructions.
Sandbox / container only: Contains blast radius; does not prove the action was authorized under policy.
Agent Passport System: Signed ActionIntent → PolicyDecision flow; depends on agent participation in the chain.

OAP emphasizes platform-level interception; sandboxes complement but do not replace authorization.

Policy as data

Named, versioned rules vs ad hoc checks

OAP / APort: Versioned policy packs (e.g. `system.command.execute.v1`, `mcp.tool.execute.v1`) with schemas and tests.
Prompts & alignment only: Implicit in prompts; changes require prompt edits and redeploy of behavior.
Sandbox / container only: Infrastructure policy (network, FS); not the same as per-capability business rules.
Agent Passport System: Delegation scopes and values floor; evolving toward OPA/Cedar-style evaluators.

Enterprise identity & assurance

Tiers that map to real-world trust

OAP / APort: Assurance levels L0–L4FIN (self-attested through KYC/financial-grade paths).
Prompts & alignment only: Not applicable.
Sandbox / container only: Not applicable.
Agent Passport System: Strong self-sovereign keys; less emphasis on tiered organizational assurance in v1.

Audit & proof

What can a third party verify?

OAP / APort: Signed decisions, passport digest, append-first audit logs; verifier integrates with registry.
Prompts & alignment only: Conversation logs only — no cryptographic authorization record per action.
Sandbox / container only: Runtime telemetry; not a substitute for per-decision proofs.
Agent Passport System: Merkle-linked receipts and three-signature chains — strong non-repudiation story.

OAP’s proof model is pragmatic for shipped guardrails; Agent Passport’s chain is strong where full agent cooperation holds.

Delegation between agents

Sub-agents and narrowed scopes

OAP / APort: Delegation formalism is a known gap on the roadmap; passport-level suspend is production-ready.
Prompts & alignment only: No standard delegation object.
Sandbox / container only: Isolation does not express delegation semantics.
Agent Passport System: First-class: `createDelegation` / `subDelegate` with depth and scope narrowing.

MCP & IDE scale

Where developers actually run agents today

OAP / APort: Shipped adapters: OpenClaw, Cursor, LangChain, CrewAI, n8n, etc.; MCP-aware packs.
Prompts & alignment only: Universal but non-enforcing.
Sandbox / container only: Depends on deployment; not MCP-specific.
Agent Passport System: No dedicated MCP server in v1.1; TypeScript-first evaluator.

Latency posture

Typical evaluation path

OAP / APort: Hosted API ~53–65 ms median in published benchmarks; local evaluation supported.
Prompts & alignment only: Zero added latency; also zero enforcement guarantee.
Sandbox / container only: VM/container overhead only.
Agent Passport System: In-memory TS; public benchmarks TBD vs OAP’s published numbers.

Pre-action authorization comparisons

When OAP is the right default

You run agents in real IDEs and frameworks, need SOX/SOC2-friendly audit, and want policy changes without retraining models.

When to combine

Use sandboxes for containment, model alignment for UX, and OAP (or another authorization layer) for allow/deny at the tool boundary — they are complementary, not competing substitutes.

Open specification

OAP is documented as an open spec with conformance artifacts. Competitors and partners can implement the same decision contract — APort ships the reference guardrails.
