WHAT IT DOES

What update_comment does on Mealie MCP Server

AI agents use update_comment to create or update resources in Mealie MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Mealie MCP Server environment.

RISK

Why update_comment is rated Medium

This tool modifies comment data reversibly (the original text can be reverted by updating again). It does not delete data (making it non-Destructive), execute code (non-Execute), handle finances (non-Financial), or merely read data (non-Read).

From the tool's definition Tool name 'update_comment' and description 'Update an existing comment's text' indicate modification of existing data.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs update_comment safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Mealie MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For update_comment, this is the rule to start with:

update_comment Rate-limited

update_comment 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.
