WHAT IT DOES

What upload_recipe_asset does on Mealie MCP Server

AI agents use upload_recipe_asset 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.

RISK

Why upload_recipe_asset is rated Medium

This tool creates or adds new asset files to recipes, which is a reversible write operation. While it modifies recipe data, it does not execute arbitrary code, delete data irreversibly, or move money. The severity is medium because uncontrolled uploads could consume storage resources or introduce unexpected file types, but the operation itself is non-destructive and reversible (assets can be removed or replaced).

From the tool's definition Tool description states 'Upload an asset file to a recipe from base64-encoded data.' The verb 'upload' and action of storing file data to a recipe indicates data creation/modification.
