List files, sizes, and update times for a reverse task artifact directory.
AI agents call list_task_artifacts to retrieve information from JS Reverse MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only retrieves and queries directory information without creating, modifying, deleting, or executing any operations. It has minimal blast radius as an AI agent could at most gain visibility into artifact organization without causing side effects. The operation is purely informational.
From the tool's definition The tool 'list_task_artifacts' performs a directory listing operation, retrieving file metadata (names, sizes, update times) with no modification or deletion capability.
Attacks that exploit this kind of access
List files, sizes, and update times for a reverse task artifact directory. It is categorised as a Read tool in the JS Reverse MCP MCP Server, which means it retrieves data without modifying state.
Register the JS Reverse MCP server in PolicyLayer and add a rule for list_task_artifacts: 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 JS Reverse MCP. Nothing to install.
list_task_artifacts 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_task_artifacts 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_task_artifacts. 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_task_artifacts is provided by the JS Reverse MCP server (noone-hub/jsreverser-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
