Set a recipe's image by scraping it from a URL. Args: slug: The unique text identifier for the recipe. image_url: URL of the image to scrape and use as the recipe image. Returns: Dict[str, Any]: Confirmation that the image was set.
AI agents use set_recipe_image_from_url 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 tool creates or modifies data (updates a recipe's image property) in a reversible manner. It does not delete data (Destructive), execute arbitrary code (Execute), move money (Financial), or merely read data (Read). The 'set' operation on a recipe image represents a Write action.
From the tool's definition Tool description states 'Set a recipe's image' and accepts a URL to scrape and assign as the recipe image. This modifies an existing recipe record by updating its image field.
Documented attack patterns abuse exactly the kind of access set_recipe_image_from_url 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 set_recipe_image_from_url:
{
"version": "1",
"default": "deny",
"tools": {
"set_recipe_image_from_url": {
"limits": [
{
"counter": "set_recipe_image_from_url_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}set_recipe_image_from_url 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.

Set a recipe's image by scraping it from a URL. Args: slug: The unique text identifier for the recipe. image_url: URL of the image to scrape and use as the recipe image. Returns: Dict[str, Any]: Confirmation that the image was set. 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 set_recipe_image_from_url: 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.
set_recipe_image_from_url 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 set_recipe_image_from_url 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 set_recipe_image_from_url. 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.
set_recipe_image_from_url 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.
