This tool modifies recipe data in batch across potentially many records, making it a Write operation. It is reversible (can be patched again), so not Destructive. Severity is high due to the batch nature affecting multiple recipes simultaneously, which could have significant impact on meal planning and recipe management if misused by an AI agent.

The rule that runs patch_many_recipes safely

patch_many_recipes 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.
The button opens the PolicyLayer dashboard: create your workspace, connect Mealie MCP Server, apply this rule, and every patch_many_recipes call is checked against it from then on.
