NARROW TOOLS · INSPECTABLE AUTHORITY
An agent can continue the case without inheriting its chat.
Countback exposes three stdio MCP tools: countback_get_case, countback_issue_count, and countback_record_count. A host reads the investigation, obtains the controller-selected task, asks an operator for a count, and records that response. The deterministic controller selects bins and verifies proposals.
| Evidence | Verified boundary |
|---|---|
| Codex registration | Local CLI configuration and exact tool surface |
| Hermes model-driven handoff | Fresh profile/workdir recovered the case and issued B; controller remained running during handoff |
| Separate MCP harness | Fresh controller and full read → issue → simulated record → resolved loop; programmatic protocol client, not a full LLM run |
| Claude Code | Configuration documented, execution unverified |
These are distinct demonstrations. The Hermes handoff alone is not proof that the backend cache was cleared. A model-driven full measurement loop is not claimed.
Run with your host
python -m countback.mcp_server
Start the local controller on port 8765 first and create a case through the application. The host gets its case ID; it does not receive hidden evaluator quantities.
