APort OAP vs Agent Passport System
Two credible authorization directions: production enforcement vs cryptographic delegation depth. Understand where each excels.
Both projects address agent authorization but optimize for different constraints. OAP emphasizes shipped, framework-level enforcement and assurance tiers for enterprise deployment.
Agent Passport System introduces strong delegation semantics and cryptographic receipt chaining. In practice, many teams may combine ideas from both models over time.
| Comparison point | OAP / APort | Agent Passport System |
|---|---|---|
| Pre-action enforcementIs every sensitive action gated before execution? | Yes — `before_tool_call` / shell hooks; model cannot bypass the platform layer. | Signed ActionIntent → PolicyDecision flow; depends on agent participation in the chain. |
| Policy as dataNamed, versioned rules vs ad hoc checks | Versioned policy packs (e.g. `system.command.execute.v1`, `mcp.tool.execute.v1`) with schemas and tests. | Delegation scopes and values floor; evolving toward OPA/Cedar-style evaluators. |
| Enterprise identity & assuranceTiers that map to real-world trust | Assurance levels L0–L4FIN (self-attested through KYC/financial-grade paths). | Strong self-sovereign keys; less emphasis on tiered organizational assurance in v1. |
| Audit & proofWhat can a third party verify? | Signed decisions, passport digest, append-first audit logs; verifier integrates with registry. | Merkle-linked receipts and three-signature chains — strong non-repudiation story. |
| Delegation between agentsSub-agents and narrowed scopes | Delegation formalism is a known gap on the roadmap; passport-level suspend is production-ready. | First-class: `createDelegation` / `subDelegate` with depth and scope narrowing. |
| MCP & IDE scaleWhere developers actually run agents today | Shipped adapters: OpenClaw, Cursor, LangChain, CrewAI, n8n, etc.; MCP-aware packs. | No dedicated MCP server in v1.1; TypeScript-first evaluator. |
| Latency postureTypical evaluation path | Hosted API ~53–65 ms median in published benchmarks; local evaluation supported. | In-memory TS; public benchmarks TBD vs OAP’s published numbers. |
Use Agent Passport System when
- You prioritize self-sovereign identity and delegation-chain semantics
- You want Merkle-style receipt proofs as a core audit primitive
- You are prototyping chain-of-delegation research workflows
Use OAP / APort when
- You need immediate framework/IDE integrations in production
- You require assurance tiers mapped to enterprise trust programs
- You need policy packs and deterministic hook enforcement today
Why teams choose OAP / APort
Production-first integrations
APort ships guardrails where agents run now, including tool-call hooks and MCP-aware policies.
Operational assurance and kill switch
Passport status and signed decisions support governance workflows and coordinated suspension strategies.
Spec + implementation track
Open specification, conformance artifacts, and implementation adapters evolve together for practical adoption.
