parse_ingredient · Mcp Mealie MCP: Risk & Policy

WHAT IT DOES

What parse_ingredient does on Mcp Mealie

AI agents invoke parse_ingredient to trigger actions in Mcp Mealie. 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

The tool processes an input string through a parsing operation to produce structured output. While it reads-like in nature (no persistent side effects), it executes a server-side computation/transformation rather than simply retrieving stored data. The blast radius is minimal as it doesn't modify any data, making severity low.

From the tool's definition 'Parse a single ingredient string into structured quantity/unit/food' - this triggers a parsing operation/computation on the server

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.
