WHAT IT DOES

What add_contact_to_project does on Filevine

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

WHY IT NEEDS A POLICY

Why add_contact_to_project needs a policy

This tool creates or modifies an association between a contact and a project, which is reversible data modification. It does not execute arbitrary code, delete data, or move money. The 'medium' severity reflects that misconfiguration could expose a contact's information to unauthorized project members in a legal case management system, but the blast radius is limited to project membership changes.

From the tool's definition add_contact_to_project with description 'Add a contact to a project with an optional role' clearly modifies project data by associating a contact record with a project.
