Add a recipe's ingredients to a shopping list. Args: list_id: The UUID of the shopping list recipe_id: The UUID of the recipe to add recipe_increment_quantity: Multiplier for recipe quantities (e.g., 2.0 for double) Returns: Dict[str, Any]: The updated shopping list
AI agents use add_recipe_to_shopping_list to create or update resources in Mealie MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Mealie MCP Server environment.
This is a Write operation because it creates or modifies data reversibly—specifically, it updates a shopping list by adding ingredients from a recipe. While it modifies state, the change is completely reversible (items can be removed), and the blast radius of misuse is minimal (a user would simply have unwanted items in a shopping list, which is easily corrected).
From the tool's definition The tool adds a recipe's ingredients to a shopping list and returns the updated shopping list. The description explicitly states it modifies an existing shopping list by appending ingredients, which is a reversible create/update operation.
Documented attack patterns abuse exactly the kind of access add_recipe_to_shopping_list gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Mealie MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for add_recipe_to_shopping_list:
{
"version": "1",
"default": "deny",
"tools": {
"add_recipe_to_shopping_list": {
"limits": [
{
"counter": "add_recipe_to_shopping_list_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}add_recipe_to_shopping_list stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

Add a recipe's ingredients to a shopping list. Args: list_id: The UUID of the shopping list recipe_id: The UUID of the recipe to add recipe_increment_quantity: Multiplier for recipe quantities (e.g., 2.0 for double) Returns: Dict[str, Any]: The updated shopping list. It is categorised as a Write tool in the Mealie MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Mealie MCP Server MCP server in PolicyLayer and add a rule for add_recipe_to_shopping_list: 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 Mealie MCP Server. Nothing to install.
add_recipe_to_shopping_list 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 add_recipe_to_shopping_list 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 add_recipe_to_shopping_list. 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.
add_recipe_to_shopping_list is provided by the Mealie MCP Server MCP server (rldiao/mealie-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
