WHAT IT DOES

What create_correspondent does on Paperless-NGX MCP Server

WHY IT NEEDS A POLICY

Why create_correspondent needs a policy

This tool creates new data (correspondent records) in the Paperless-NGX system but does not delete, overwrite, execute external code, or move money. Creation of metadata entries like correspondents is a reversible write operation with minimal blast radius - a misused tool would simply add unwanted correspondent records, which can be removed.

From the tool's definition Tool description states 'Create a new correspondent' - a write operation that creates a new entity in the system. The action is reversible (correspondents can be deleted), and the scope is limited to metadata management for document organization.
