AI agents call nutrition_find_by_macros to retrieve information from SAVORDISH 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 nutrition_find_by_macros 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.

Find recipes that match specific nutritional targets. Filter by max calories, minimum protein, max carbs, max fat — perfect for fitness goals, dieting, or health-conscious eating. TRIGGERS: - 'high protein recipes', 'recipes under 400 calories' - 'low carb meals', 'high fiber recipes' - 'keto-friendly recipes by nutrition', 'recipes for muscle building' - 'meals under 500 calories with at least 30g protein' - 'find recipes for my diet', 'low calorie dinner options'. It is categorised as a Read tool in the SAVORDISH MCP Server, which means it retrieves data without modifying state.
Register the SAVORDISH MCP server in PolicyLayer and add a rule for nutrition_find_by_macros: 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 SAVORDISH. Nothing to install.
nutrition_find_by_macros 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 nutrition_find_by_macros 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 nutrition_find_by_macros. 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.
nutrition_find_by_macros is provided by the SAVORDISH MCP server (savordish/savor-dish). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
