AI agents call discover_products to retrieve information from Tru without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
app | string | Yes | The app's service_name (e.g. 'my-app') or UUID |
Parameters from the server's own tool schema.
This tool retrieves and displays product and pricing data without creating, modifying, deleting, or executing any actions. It is a straightforward catalog query that an AI agent would use to inform users about available products. No reversible or irreversible changes occur, no code is executed, and no financial transactions are initiated—only data is retrieved.
From the tool's definition Tool description states it "List products and pricing available" and "Returns the product catalog" — purely information retrieval with no side effects. The verb 'List' and 'Returns' indicate a read-only query operation.

Register the Tru MCP server in PolicyLayer and add a rule for discover_products: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Tru. Nothing to install.
discover_products is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the discover_products rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for discover_products. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
discover_products is provided by the Tru MCP server (tru-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
discover_products is one line of Tru's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
