WHAT IT DOES

What met-list-objects does on Meta Data Mcp

RECOMMENDED RULE

The rule that runs met-list-objects safely

met-list-objects Allowed

met-list-objects is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Meta Data Mcp, apply this rule, and every met-list-objects call is checked against it from then on.
