seed_group_units · Mealie MCP Server MCP: Risk & Policy

WHAT IT DOES

What seed_group_units does on Mealie MCP Server

AI agents invoke seed_group_units 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 seed_group_units needs a policy

The tool 'runs' a seeder, which is an execution action that creates/populates unit data in the group. Seeders typically write bulk data but are triggered as an operation rather than a simple write. The blast radius is medium as it could overwrite or flood existing units data, but it is likely reversible.

From the tool's definition 'Run the group units seeder' — executes a seeder operation that populates/initializes data

seed_group_units Rate-limited

seed_group_units 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.
