Get test cycle IDs linked to a Jira issue.
AI agents call get_issue_link_test_cycles to retrieve information from Zephyr Scale MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves existing data (test cycle IDs associated with a Jira issue) without modifying, creating, deleting, or executing anything. It is a read-only operation that returns information from the Zephyr Scale system. The low severity reflects minimal blast radius—an AI agent calling this repeatedly or with different inputs would only retrieve data, with no unintended consequences.
From the tool's definition Tool name includes 'get_' and description uses 'Get test cycle IDs linked to a Jira issue', indicating a retrieval operation with no side effects.

Register the Zephyr Scale MCP Server MCP server in PolicyLayer and add a rule for get_issue_link_test_cycles: 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 Zephyr Scale MCP Server. Nothing to install.
get_issue_link_test_cycles is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_issue_link_test_cycles 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.
