AI agents call check_pesticide_mrl to retrieve information from Food Safety 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 check_pesticide_mrl 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.

Check Israeli official pesticide Maximum Residue Limits (MRL) by pesticide active substance, crop, or pesticide-crop pair. Input: pesticide name, crop name, or combined query in Hebrew or English (e.g. 'glyphosate', 'tomato', 'chlorpyrifos apple'). Returns: active substance, crop (Hebrew and English), official MRL value in mg/kg (ppm), last update date, and pending regulatory changes. Source: Israel Ministry of Health Pesticide Residue Limits (3,708 pesticide-crop MRL records). For agricultural compliance and food safety residue assessment. Do not use for food additive safety (use check_additive), cannabis pesticide limits, or non-Israeli MRL regimes.. It is categorised as a Read tool in the Food Safety MCP Server, which means it retrieves data without modifying state.
Register the Food Safety MCP server in PolicyLayer and add a rule for check_pesticide_mrl: 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 Food Safety. Nothing to install.
check_pesticide_mrl 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 check_pesticide_mrl 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 check_pesticide_mrl. 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.
check_pesticide_mrl is provided by the Food Safety MCP server (https://food-mcp-server.rootsbybenda.workers.dev/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
