What create_test_case does on Huly
AI agents use create_test_case 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.
Why create_test_case is rated Medium
This tool creates a new test case entity within a test suite, which is a reversible Write operation. The data can typically be updated or deleted later. It has moderate blast radius since bulk creation of test cases could clutter a test suite, but does not permanently destroy data or execute arbitrary code. Severity is medium rather than low due to potential for workflow disruption via mass creation.
From the tool's definition Tool name 'create_test_case' and description 'Create a test case attached to a suite' indicate data creation.
Attacks that exploit this kind of access
The rule that runs create_test_case 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 create_test_case, this is the rule to start with:
create_test_case 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 create_test_case call is checked against it from then on.

create_test_case is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the create_test_case 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.
Set action: deny in the PolicyLayer policy for create_test_case. 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.
