WHAT IT DOES

What update_project does on MCP Personal Assistant

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

WHY IT NEEDS A POLICY

Why update_project needs a policy

Updating a project modifies data reversibly—projects can be further updated or reverted. This is a Write operation, not Destructive (which would be irreversible deletion). Severity is medium because misuse could corrupt or alter important project information, but the blast radius is limited to a single user's project data rather than system-wide or financial impact.

From the tool's definition Tool name 'update_project' and description 'Update a project' indicate modification of existing project data. The context shows this is a personal productivity server managing projects, todos, and documents.
