List all test plans and test files in the project. Returns specs/ and tests/ directories.
AI agents call test_artifacts_list to retrieve information from MCP Playwright 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 enumerates test artifacts from specified directories without creating, modifying, deleting, or executing anything. It is a read-only query operation with minimal blast radius—exposure only risks disclosure of test file names and structure, not execution or data corruption.
From the tool's definition Tool name 'test_artifacts_list' and description 'List all test plans and test files in the project' indicate a listing/query operation with no modification capability. The action is purely retrieval-focused ('List', 'Returns').
Attacks that exploit this kind of access
List all test plans and test files in the project. Returns specs/ and tests/ directories. It is categorised as a Read tool in the MCP Playwright Server MCP Server, which means it retrieves data without modifying state.
Register the MCP Playwright Server MCP server in PolicyLayer and add a rule for test_artifacts_list: 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 MCP Playwright Server. Nothing to install.
test_artifacts_list 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 test_artifacts_list 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 test_artifacts_list. 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.
test_artifacts_list is provided by the MCP Playwright Server MCP server (j0hanz/playwright-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
