update_project_contact · Filevine MCP: Risk & Policy

WHAT IT DOES

What update_project_contact does on Filevine

AI agents use update_project_contact 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 update_project_contact needs a policy

The tool creates or modifies project contact data reversibly. While it affects important case management metadata in a legal context, the change is not destructive and not a side-effect-free read. Context from sibling tools (archive_project, approve_invoice, batch operations) indicates this is part of a legal case management system where data modifications are routine.

From the tool's definition Tool name 'update_project_contact' with description 'Update a contact's role or attributes on a project' indicates modification of existing contact metadata. This is reversible (attributes can be changed again) and does not delete or execute code.
