CAIN-42 vs AWS Bedrock AgentCore + Agent Registry
AgentCore is a set of modular services: a microVM runtime, Identity, a managed MCP Gateway, Memory, a Cedar-based Policy engine, Browser, Code Interpreter and Evaluations. The AWS Agent Registry (GA 2026-08-31) catalogs agents, tools, skills and MCP servers with a review/approval lifecycle.
What AWS Bedrock AgentCore + Agent Registry does well
- Managed runtime, memory and a managed MCP gateway in one cloud.
- Cedar policy with a LOG_ONLY to ENFORCE rollout.
- AWS compliance, global regions and IAM integration.
What CAIN-42 does differently
- Enforces at the tool-call boundary, before anything runs.
- Orders authorization through a Byzantine quorum (3-of-4): one "yes" is never enough.
- Leaves a per-action signed receipt you can verify offline with a clean-room verifier.
- Authority continuity: a change to the model, tool, memory, skill or delegation forces a re-check.
- Self-serve from $19.75/mo; runs hosted, self-hosted or air-gapped.
Capability difference
| Capability | CAIN-42 | AWS Bedrock AgentCore + Agent Registry | Source (verified 2026-10-14) |
|---|---|---|---|
| Primary focus | Runtime governance in the execution path | Managed agent runtime, gateway and policy in AWS | AWS source page verified 2026-10-14 |
| Blocks the tool call at the boundary | Yes — MCPGate halts before the tool runs | Yes (Gateway interceptor + Cedar) | |
| Byzantine-ordered authorization (quorum cert) | Yes — 3-of-4 PBFT quorum certificate | No* | |
| Per-action signed receipt, offline-verifiable | Yes — Ed25519, hash-chained, offline-verifiable | CloudTrail / CloudWatch audit records | |
| Authority continuity across change | Yes — a change forces an authority re-check | No* | |
| Vendor-neutral / self-hostable | Hosted, self-hosted or air-gapped | AWS-only managed service | |
| Public entry price | $19.75/mo self-serve | Usage-based (talk to sales) |
When to pick which
Pick AgentCore when you are all-in on AWS and want managed runtime, memory and Cedar policy. Pick CAIN-42 when you want an enforcing gate that is cloud-agnostic and self-hostable, with a quorum-ordered authorization and an offline-verifiable receipt.
