Get all versions of a test case.
AI agents call get_test_case_versions 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 versions of a test case from Zephyr Scale, which is a read-only query operation. It queries data without creating, modifying, deleting, or executing anything. The blast radius of misuse is minimal—an agent could retrieve version history but cannot alter or delete test data.
From the tool's definition Tool name 'get_test_case_versions' and description 'Get all versions of a test case' indicate a retrieval operation with no side effects.
Attacks that exploit this kind of access
Get all versions 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_versions: 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_versions 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_versions 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_versions. 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_versions 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.
