AI agents use create_test_cycle to create or update resources in JIRA Zephyr MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your JIRA Zephyr MCP Server environment.
This tool creates a new test cycle, which is a reversible operation that adds data to the system. It does not execute tests (that's execute_test's role), does not delete or permanently alter existing data, and involves no financial transactions. The impact is localized to test management records, making it Write-category.
From the tool's definition Tool name 'create_test_cycle' and description 'Create a new test execution cycle' indicate data creation. The verb 'Create' combined with the context of test management systems shows this tool adds new records to JIRA Zephyr.
Documented attack patterns abuse exactly the kind of access create_test_cycle gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and JIRA Zephyr MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for create_test_cycle:
{
"version": "1",
"default": "deny",
"tools": {
"create_test_cycle": {
"limits": [
{
"counter": "create_test_cycle_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
} create_test_cycle 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.
Free to start. No card required.
Create a new test execution cycle. It is categorised as a Write tool in the JIRA Zephyr MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the JIRA Zephyr MCP Server MCP server in PolicyLayer and add a rule for create_test_cycle: 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 JIRA Zephyr MCP Server. Nothing to install.
create_test_cycle 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_cycle 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_cycle. 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.
create_test_cycle is provided by the JIRA Zephyr MCP Server MCP server (leorosignoli/jira-zephyr-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from JIRA Zephyr MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
