cMCP embeds AGT. The Cedar policy engine, SPIFFE identity, and Merkle audit chain are AGT. cMCP adds the TEE boundary, hardware key generation, and Level 2 TRACE emission.

When cMCP emits a Level 2 record for a session, it supersedes any Level 0 record AGT might have emitted for the same session. The two records are linked by shared `subject` and `tool_transcript.hash`.

## On-premises deployment

For on-premises Intel TDX (e.g., Supermicro SYS-121H with Xeon Scalable 4th Gen), the cMCP gateway runs as a TD and uses Intel's PCCS (Platform Certificate Caching Service) or the Intel Trust Authority for attestation verification. No cloud dependency is required — deploy PCCS locally to air-gap the attestation path. See [agentrust-io/cmcp](https://github.com/agentrust-io/cmcp) for the Helm chart.

```yaml
# cmcp.yaml (on-premises TDX)
attestation:
platform: intel-tdx
pccs_url: https://pccs.internal.example.org:8081 # your local PCCS
rim_cache: /var/cache/trace/rims
```

## Example record

See [`examples/intel-tdx.json`](https://github.com/agentrust-io/trace-spec/blob/main/examples/intel-tdx.json).
