WHAT IT DOES

What export_table does on Professor Fit MCP

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

WHY IT NEEDS A POLICY

Why export_table needs a policy

Export functions create new data artifacts (files, formatted outputs) by transforming existing data. This is a Write operation—it produces new data objects but is reversible (exported files can be deleted). The medium severity reflects that exporting professor profiles could expose PII or research data, but the impact depends on where/how the export is used.

From the tool's definition Tool name 'export_table' combined with server context showing 'profiles_export' as a sibling tool suggests this exports data.
