RISK

Why create_collection is rated Medium

Creating a collection is a write operation that adds a new resource to Metabase. It modifies the platform state by introducing a new collection structure that can organize cards and dashboards, but the operation is reversible (collections can be deleted). This is not destructive since it doesn't delete data.

From the tool's definition Tool name is 'create_collection' and description states 'Create a new collection in Metabase' — this creates a new organizational container/resource in the analytics platform.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs create_collection safely

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

create_collection Rate-limited

create_collection 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.

        }
      ]
    }
  }
}
