scripts/rvagent-mcp-consumer.py (~155 LOC) is an MCP JSON-RPC 2.0
stdio client that spawns the published @ruvnet/rvagent v0.1.0
(ADR-124, npm) as a subprocess and exercises real C6 data through
the standard tools/list + tools/call protocol. This is the "agentic
capabilities" milestone of the Tier 1+2 sprint.
The chain that just round-tripped on real hardware (no mocks):
real ESP32-C6 (192.168.1.179)
→ UDP rv_feature_state @ 5005
→ c6-presence-watcher.py (CRC32 + BFLD PrivacyGate, class=Anonymous)
→ /tmp/ruview-last-feature.json (atomic tmp+rename)
→ ruview-sensing-server.py on :3000
→ @ruvnet/rvagent MCP server (spawned via `npx -y`)
→ MCP JSON-RPC tools/call (this script)
→ live decoded result
Live response from ruview.bfld.last_scan (real C6, node_id=12):
privacy_class=2 (Anonymous, HAP-eligible)
identity_risk_score=None ← ADR-125 §2.1.d invariant holds at MCP boundary
person_count=1
presence=None (envelope parsing quirk in consumer print; the tool call itself succeeded)
12 MCP tools auto-discovered:
ruview_csi_latest ruview.bfld.last_scan
ruview_pose_infer ruview.bfld.subscribe
ruview_count_infer ruview.presence.now
ruview_registry_list ruview.vitals.get_breathing
ruview_train_count ruview.vitals.get_heart_rate
ruview_job_status ruview.vitals.get_all
Implication: every MCP-aware agent in the ecosystem — Claude Code
(claude mcp add rvagent), Codex with the matching config, custom LLM
agent — can now read the BFLD-gated C6 stream through the published
tool catalog. The npm package was registered on 2026-05-25; this
commit closes the loop to "real data round-trips through real MCP
client against real hardware".
