WHAT IT DOES

What update_recipe does on Saffron MCP Server

WHY IT NEEDS A POLICY

Why update_recipe needs a policy

This tool modifies existing recipe data reversibly. It is a Write operation because updates can be undone (recipes can be re-updated to previous values, deleted, or restored from backups in typical recipe management systems). While it affects data, it does not irreversibly delete content (Destructive), execute arbitrary commands (Execute), or move money (Financial).

From the tool's definition Tool name 'update_recipe' combined with description 'Update an existing recipe' indicates modification of existing data. The server description mentions 'creating and updating recipes' as core functionality.
