Get a specific version of a test case.
AI agents call get_test_case_version 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 retrieves historical version data from test cases without modifying, deleting, or executing anything. It is purely a query operation that reads existing data from the Zephyr Scale system. The 'get' verb and read-only nature of version retrieval place it clearly in the Read category with low severity.
From the tool's definition Tool name 'get_test_case_version' and description 'Get a specific version of a test case' indicate a retrieval operation with no side effects.

Get a specific version of a test case. It is categorised as a Read tool in the Zephyr Scale MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Zephyr Scale MCP Server MCP server in PolicyLayer and add a rule for get_test_case_version: 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_test_case_version 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_test_case_version 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 get_test_case_version. 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.
get_test_case_version is provided by the Zephyr Scale MCP Server MCP server (metquay/zephyr-scale-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
