AI agents call get_test_case to retrieve information from Tuskr without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves data about a single test case using an identifier (key or id). It performs a query/fetch operation without creating, modifying, deleting, or executing any actions. The narrow scope (single test case retrieval) and lack of side effects classify it as a Read operation with low severity.
From the tool's definition Tool description states 'Get one detailed test-case' - a retrieval operation with no modification or side effects. The verb 'Get' and the read-only nature of retrieving a test case by identifier are clear indicators.
Attacks that exploit this kind of access
Get one detailed test-case by key (C-xxxx) or id. It is categorised as a Read tool in the Tuskr MCP Server, which means it retrieves data without modifying state.
Register the Tuskr MCP server in PolicyLayer and add a rule for get_test_case: 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 Tuskr. Nothing to install.
get_test_case 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 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. 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 is provided by the Tuskr MCP server (zapkid/tuskr-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
