WHAT IT DOES

What restore_db does on Metis Public Health

AI agents use restore_db to create or update resources in Metis Public Health, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Metis Public Health environment.

RISK

Why restore_db is rated Medium

A database restore operation modifies the current state of data by replacing it with a prior version. While it does not permanently delete original data (the backup remains), it does irreversibly alter the current database state and could overwrite recent changes.

From the tool's definition Tool name 'restore_db' indicates restoration/recovery of a database, which involves modifying or overwriting the current database state with a previous snapshot or backup.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs restore_db safely

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

restore_db Rate-limited

restore_db 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.
