AI agents call list_test_sets to retrieve information from Xray MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves test set information from Jira without creating, modifying, deleting, or executing anything. It is a straightforward data query operation with no destructive or operational side effects. The blast radius of misuse is minimal—an attacker could only discover what test sets exist in the project.
From the tool's definition Tool name 'list_test_sets' and description 'List all test sets in a Jira project' indicate a retrieval operation with no side effects. The verb 'list' is a classic read operation that queries and returns data without modification.
Attacks that exploit this kind of access
List all test sets in a Jira project. It is categorised as a Read tool in the Xray MCP MCP Server, which means it retrieves data without modifying state.
Register the Xray MCP server in PolicyLayer and add a rule for list_test_sets: 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 Xray MCP. Nothing to install.
list_test_sets 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 list_test_sets 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 list_test_sets. 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.
list_test_sets is provided by the Xray MCP server (korfu/mcp-xray). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
