WHAT IT DOES

What attach_tag does on Huly

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

RISK

Why attach_tag is rated Medium

Modifies object metadata by attaching tags; reversible operation without data deletion or financial impact.

From the tool's definition Attach a generic Huly tag to one raw object collection; idempotent

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs attach_tag 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 attach_tag, this is the rule to start with:

attach_tag Rate-limited

attach_tag 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.

FAQ

Questions about attach_tag

What does the attach_tag tool do? +

Attach a generic Huly tag to one raw object collection. Prefer module tools for supported issue, document, Planner, board, and recruiting objects; this SDK fallback requires targetClass plus objectId/objectClass/space/collection and is idempotent for the same object, collection, and tag. It is categorised as a Write tool in the Huly MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on attach_tag? +

Register the Huly MCP server in PolicyLayer and add a rule for attach_tag: 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 attach_tag? +

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

Can I rate-limit attach_tag? +

Yes. Add a rate_limit block to the attach_tag 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 attach_tag completely? +

Set action: deny in the PolicyLayer policy for attach_tag. 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.

What MCP server provides attach_tag? +

attach_tag is provided by the Huly MCP server (@firfi/huly-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
