What audit_price_consistency does on Tanod
AI agents call audit_price_consistency to retrieve information from Tanod without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
origin | string | Yes | Public https seller origin only (host name, port 443; no path, query, credentials or IP literal). Reads /openapi.json, /mcp and /llms.txt. |
Parameters from the server's own tool schema.
Why audit_price_consistency is rated Low
Even though audit_price_consistency only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.
Attacks that exploit this kind of access
The rule that runs audit_price_consistency safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Tanod, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For audit_price_consistency, this is the rule to start with:
audit_price_consistency is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Tanod, apply this rule, and every audit_price_consistency call is checked against it from then on.
