WHAT IT DOES

What add_template_child does on Huly

AI agents use add_template_child 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 add_template_child is rated Medium

This tool creates or modifies template data structures within the project management system. While it affects how future issues are created (through default values), it does not execute arbitrary operations, delete data, or move money. The modification is reversible, classifying it as Write.

From the tool's definition add_template_child creates a child template defining default values for sub-issues. This modifies template configuration data reversibly (the child template can be removed or modified later).

RECOMMENDED RULE

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

add_template_child Rate-limited

add_template_child 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.

How do I enforce a policy on add_template_child? +

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

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

Can I rate-limit add_template_child? +

Yes. Add a rate_limit block to the add_template_child 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_template_child completely? +

Set action: deny in the PolicyLayer policy for add_template_child. 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 add_template_child? +
