AI agents call find_product to retrieve information from Rootvine without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though find_product only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

These attack patterns abuse exactly the kind of access find_product gives an agent. Each links to the full case and the policy that stops it:
Other read tools across the catalogue. The same approach applies to each: allow, with a rate cap to control cost.
Smart router — finds the best place to stream, buy, or collect any supported product. Automatically detects the product category and routes to the right resolver. Music is live (stream, digital purchase, vinyl, CD, collector editions). Games, books, films, podcasts, and live event tickets are rolling out. Use this when the query is ambiguous or when music could be streamed, purchased digitally, or found on physical media.. It is categorised as a Read tool in the Rootvine MCP Server, which means it retrieves data without modifying state.
Register the Rootvine MCP server in PolicyLayer and add a rule for find_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 Rootvine. Nothing to install.
find_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 find_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 find_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.
find_product is provided by the Rootvine MCP server (rootvine-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
