AI agents use nutrition_meal_score to create or modify resources in SAVORDISH. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.
Without a policy, an AI agent could call nutrition_meal_score repeatedly, creating or modifying resources faster than any human could review. PolicyLayer's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach SAVORDISH.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

Rate the nutritional quality of a meal plan or set of recipes on a 0-100 health score. Evaluates balance of protein, fiber, calorie density, and variety. TRIGGERS: - 'rate my meal plan', 'how healthy is my meal selection' - 'score these recipes nutritionally', 'nutrition grade for these meals' - 'is this a balanced meal plan', 'health check my recipes'. It is categorised as a Write tool in the SAVORDISH MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the SAVORDISH MCP server in PolicyLayer and add a rule for nutrition_meal_score: 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_meal_score is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the nutrition_meal_score 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_meal_score. 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_meal_score 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.
