List all available test files, suites, and tests without running them. Optionally filter the list.
AI agents call lupa_list_tests to retrieve information from Lupa 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 and queries test metadata without executing any tests, modifying data, or triggering external operations. It is purely informational and carries minimal risk of misuse by an AI agent.
From the tool's definition Tool description states 'List all available test files, suites, and tests without running them.' The verb 'list' and explicit 'without running them' indicate this is a read-only operation with no side effects.
Attacks that exploit this kind of access
List all available test files, suites, and tests without running them. Optionally filter the list. It is categorised as a Read tool in the Lupa MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Lupa MCP Server MCP server in PolicyLayer and add a rule for lupa_list_tests: 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 Lupa MCP Server. Nothing to install.
lupa_list_tests 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 lupa_list_tests 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 lupa_list_tests. 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.
lupa_list_tests is provided by the Lupa MCP Server MCP server (pawel-up/lupa-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
