results_export_data · COMSOL MCP Server MCP: Risk & Policy

WHAT IT DOES

What results_export_data does on COMSOL MCP Server

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

WHY IT NEEDS A POLICY

Why results_export_data needs a policy

Export operations create new files or data artifacts (e.g., CSV, HDF5, images) without deleting originals, making this a Write action rather than Read (which would only retrieve without transformation).

From the tool's definition Tool name 'results_export_data' indicates data export functionality. The empty description provides no detail on format, destination, or scope, but the action of exporting simulation results constitutes data creation/writing to an external format or storage…

results_export_data Rate-limited

results_export_data stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
