Get all unique product categories available in the catalog.
AI agents call get_categories to retrieve information from Product Recommendation System without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only retrieval of categorical metadata from a product catalog. It has no side effects, does not modify data, and poses minimal risk if misused by an AI agent. The operation is equivalent to a simple database SELECT query on category enumeration.
From the tool's definition Tool name 'get_categories' and description 'Get all unique product categories available in the catalog' indicate a query operation that retrieves metadata without modifying data.
Attacks that exploit this kind of access
Get all unique product categories available in the catalog. It is categorised as a Read tool in the Product Recommendation System MCP Server, which means it retrieves data without modifying state.
Register the Product Recommendation System MCP server in PolicyLayer and add a rule for get_categories: 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 Product Recommendation System. Nothing to install.
get_categories 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 get_categories 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 get_categories. 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.
get_categories is provided by the Product Recommendation System MCP server (josephazar/products-recommendation-mcp-maf). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
