parse_ingredient · Mealie MCP Server MCP: Risk & Policy

WHAT IT DOES

What parse_ingredient does on Mealie MCP Server

AI agents invoke parse_ingredient to trigger actions in Mealie MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why parse_ingredient needs a policy

This tool sends data to an external parser endpoint to process/transform an ingredient string. It triggers an external operation (calling Mealie's parser API) rather than simply reading stored data or writing/modifying records. The blast radius is low since it's a parsing operation with no persistent side effects on data.

parse_ingredient Rate-limited

parse_ingredient stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
