WHAT IT DOES

What list_card_versions does on Huly

AI agents call list_card_versions to retrieve information from Huly without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why list_card_versions is rated Low

This tool retrieves historical versions or metadata of a card without modifying, deleting, or executing external operations. The 'Read' designation in the description and 'list' action confirm it is a read-only query operation with minimal security impact.

From the tool's definition Tool name 'list_card_versions' and description 'Read one page of a Huly card' explicitly indicate retrieval of data with the word 'Read' and 'list', which are standard Read operations.

RECOMMENDED RULE

The rule that runs list_card_versions safely

list_card_versions Allowed

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

  "tools": {
    "list_card_versions": {}
  }
}

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

The button opens the PolicyLayer dashboard: create your workspace, connect Huly, apply this rule, and every list_card_versions call is checked against it from then on.
