+# ramen-ai cMCP Adapter integration with cMCP + TRACE
+
+Intercepts tool calls at the [cMCP](https://github.com/agentrust-io/cmcp)
+boundary, evaluates their semantic intent against configured compliance policies
+via the [ramen-ai](https://ramenai.dev) API, and maps the resulting V5
+Ed25519-signed receipt onto a TRACE Trust Record (EAT profile
+`tag:agentrust.io,2026:trace-v0.1`).
+
+Source: [ramen-ai-dev/ramen-ai-integrations — plugins/cmcp-python](https://github.com/ramen-ai-dev/ramen-ai-integrations/tree/master/plugins/cmcp-python)
+
+## Run it
+
+Against released packages (`agentrust-trace` 0.3.0, `cmcp-runtime` 0.3.0):
+
+```bash
+pip install agentrust-trace agentrust-trace-tests cmcp-runtime
+pip install -e "integrations/ramen-ai-cmcp[test]"
+pytest integrations/ramen-ai-cmcp/tests -q
+python integrations/ramen-ai-cmcp/examples/emit_record.py --out trust-record.jwt
+trace-tests verify --record trust-record.jwt --level 0
+```
+
+## What is verified
+
+- `ramen_ai_trace.build_trace_record` maps a committed V5 fixture receipt onto
+  TRACE fields: `policy.bundle_hash` (`sha256:<payload_hash>`), `runtime.measurement`
+  (receipt UUID), `subject` (`spiffe://ramenai.dev/evaluation/<receipt_id>`),
+  `appraisal.status` (`affirming` / `denying`).
+- `agentrust_trace.sign_record` signs the record with an ephemeral Ed25519 key
+  and `agentrust_trace.verify_record(..., allow_embedded_key=True)` verifies the
+  round-trip; `tests/` includes a tamper probe that must fail verification.
+- `trace-tests verify --level 0` passes on the emitted record (8 checks).
+
+## What it does NOT claim
+
+See rules 2 and 4 in [CONTRIBUTING.md](../../CONTRIBUTING.md).
+
+- **Level 0 carries a TR-SIG-005 UNVERIFIED finding.** The `agentrust-trace-tests`
+  loader rejects any plain record carrying a top-level `signature` field
+  (anti-downgrade), so the gradable record is the unsigned payload. The signed
+  form is written alongside it (`<out>.signed.json`) and verifies with
+  `agentrust_trace.verify_record`.
+- The ephemeral signing key proves the sign/verify path works; it does **not**
+  chain to a trusted issuer.
+- `runtime.platform` is `software-only`. No TEE, hardware root of trust, or
+  attested-execution claim is made.
+- The ramen-ai evaluation API requires `RAMEN_API_KEY` and `OPENAI_API_KEY`
+  (BYOK on Starter/Professional tiers). The conformance workflow does not call
+  the live API — it maps a committed fixture receipt offline.
+- V5 receipts bind policy UUIDs but not rule content (policies are mutable under
+  the same UUID). See `v5-conformance.md §6` in the ramen-ai-integrations repo.
+
+## Conformance CI
+
+The repository-root workflow
+[`.github/workflows/ramen-ai-cmcp-conformance.yml`](../../.github/workflows/ramen-ai-cmcp-conformance.yml)
+(path-scoped to this directory) installs the released agentrust-io packages,
+runs the mapping tests, emits a record, and runs `trace-tests verify --level 0`
+across Python 3.11–3.14. A clean matrix run is the basis for the Verified tier.
