Read-only access to the OPERANT benchmark: AI operating-agent calibration methodology, case library, and retained calculation views. The named-model rows are not durable performance claims and must not be ranked. OPERANT measures whether an agent correctly discriminates guarded vs. safe actions (OCS = TPR - FPR). Start with get_results for the evidence boundary or get_methodology for benchmark design; use list_cases and get_case to explore the case library.

- Is operant-mcp live?
- Yes — it answered the hub's last check (checked 2h ago). It answered 100% of checks over the last 30 days.
- Is operant-mcp free to use?
- Yes — the hub reached it with no key and no payment.
- What tools does operant-mcp have?
- 5 tools: get_case, compare_models, get_results, list_cases, get_methodology.
- Is operant-mcp safe to connect?
- The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.
get_results reads open 2h ago
Return retained model calculation profiles plus generated_at, claim_status, claims_at_risk, and the bounded evidence_binding. These rows are not durable named-model performance claims. Do not rank them or treat stdev/significance as reliable model evidence.
{ "type": "object", "$schema": "http://json-schema.org/draft-07/schema#", "properties": {} }arguments 5 lineslist_cases reads open 2h ago
Return case metadata (no full task prompts): pair_id/id, axis, tier, grounding, and side indicators (malign/benign for axes 1/2/4; null for axis 3). Filter by axis, or omit for all cases across all axes (the result includes a count). Use get_case to fetch a full case with task prompts and expected decisions.
{ "type": "object", "$schema": "http://json-schema.org/draft-07/schema#", "properties": { "axis": { "enum": [ "refusal-calibration", "sanctioned-path", "orchestration", "escalation-reroute" ], "type": "string", "description": "Axis to filter by: refusal-calibration | sanctioned-path | orchestration | escalation-reroute" } }, "additionalProperties": false }arguments 17 linesget_methodology reads open 17h ago
Return the benchmark design: the 4 axes, the OCS formula (Youden's J), the 5 decision labels (PROCEED, PROCEED_SANCTIONED, REFUSE, ESCALATE, REROUTE), scoring blocks, and a concise what-it-measures / what-it-doesn't summary. Sourced from the baked case-file metadata.
{ "type": "object", "$schema": "http://json-schema.org/draft-07/schema#", "properties": {} }arguments 5 linesget_case reads unknown 17h ago
Return the full case for a given pair_id (axes 1/2/4) or id (axis 3): malign and benign task prompts, expected decisions, grounding rationale, and bypass patterns. Axis 3 cases are single (unmatched) and use an 'id' field instead of 'pair_id'. Use list_cases to browse available ids.
{ "type": "object", "$schema": "http://json-schema.org/draft-07/schema#", "required": [ "pair_id", "axis" ], "properties": { "axis": { "enum": [ "refusal-calibration", "sanctioned-path", "orchestration", "escalation-reroute" ], "type": "string", "description": "The axis this case belongs to" }, "pair_id": { "type": "string", "minLength": 1, "description": "The pair_id (axes 1/2/4) or id (axis 3) to retrieve" } }, "additionalProperties": false }arguments 26 linescompare_models reads unknown 2h ago
Place two retained calculation profiles side by side by display_name substring. Returns ocs_mean, ocs_stdev, orchestration_mean, run_family, and subject_shell for each, plus comparison_status=NOT_DURABLE and the public claim_status. This is not evidence that either named model outperforms, equals, or differs significantly from the other. If a name is ambiguous or not found, returns an error listing all available display_names.

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.
Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.
- Sign any request with an ed25519 key — that binds it:
GET /api/v1/me, thenPOST /api/v1/passport. - Prove it is yours. Easiest: put
brick-blue-key=<your key>in your MCP server's instructions — or a DNS TXT record / a file on the domain. - Ask the hub to check:
POST /api/v1/passport/claim-endpointwith this listing's id8214c83d3841fb43.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/8214c83d3841fb43/claim.
Over MCP: the claim_endpoint tool.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.
An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.
MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
