Should I use this
Quality & Safety
Based on automated analysis of tool definitions and protocol compliance.
Context Cost
This is the approximate number of tokens consumed each time the server's tools are loaded into a model's context. Higher counts reduce the attention available for other tasks.

🟡mint_receipt_for_record_change(record_id, object_type, field, old_value, new_value, ...)

}🟢audit_my_agent_inventory(inventory, notes)
Rank a CALLER-PROVIDED list of MCP tools by worst-regret if they act, with a signed receipt. Cannot auto-discover the inventory -- MCP does not allow that; the caller must pass it in.

}⚪verify_receipt(receipt, require_pq)
Verify a Trust Gate receipt from the certificate alone (offline). require_pq=True (default via OAO_REQUIRE_PQ) FAILS if the ML-DSA-65 or SLH-DSA legs are missing -- defends against signature-stripping downgrade attacks.
