RECOMMENDED RULE

The rule that runs add_document_label safely

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

add_document_label Rate-limited

add_document_label 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.

  }
}

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

FAQ

Questions about add_document_label

What does the add_document_label tool do? +

How do I enforce a policy on add_document_label? +

Register the Huly MCP server in PolicyLayer and add a rule for add_document_label: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Huly. Nothing to install.

What risk level is add_document_label? +

add_document_label is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit add_document_label? +

Yes. Add a rate_limit block to the add_document_label rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block add_document_label completely? +

Set action: deny in the PolicyLayer policy for add_document_label. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
