AI agents call lookup_product to retrieve information from Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or queries product information without side effects. It performs lookups and searches, which are classic Read operations. There is no evidence of creating, modifying, deleting data, or executing code. The low severity reflects minimal blast radius if misused—at worst, an agent could enumerate product information.
From the tool's definition Tool name 'lookup_product' and description 'Look up product details by SKU or search by name' indicates read-only data retrieval operations with no modification, deletion, or execution capabilities.
Attacks that exploit this kind of access
Look up product details by SKU or search by name. It is categorised as a Read tool in the Server MCP Server, which means it retrieves data without modifying state.
Register the Server MCP server in PolicyLayer and add a rule for lookup_product: 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 Server. Nothing to install.
lookup_product 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 lookup_product 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 lookup_product. 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.
lookup_product is provided by the Server MCP server (@nest-mcp/server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
