lenx_export_task_data · Lenx MCP Server MCP: Risk & Policy

WHAT IT DOES

What lenx_export_task_data does on Lenx MCP Server

AI agents use lenx_export_task_data to create or update resources in Lenx MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Lenx MCP Server environment.

WHY IT NEEDS A POLICY

Why lenx_export_task_data needs a policy

The tool generates and exports data to an external system (email), which are reversible write operations. While it doesn't modify the underlying monitoring tasks themselves, it creates new artifacts (export files) and triggers email delivery. This is more severe than a simple Read operation (which would only retrieve data) but less severe than Destructive (no data deletion) or Execute (no arbitrary code execution).

From the tool's definition Tool description states it "Request[s] a CSV or XLSX export of task post data" and sends "Results...to the specified email address." This creates/generates an export file and initiates an email transmission, both write operations with side effects.
