create_plane_project · Ghost MCP Server MCP: Risk & Policy

WHAT IT DOES

What create_plane_project does on Ghost MCP Server

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

WHY IT NEEDS A POLICY

Why create_plane_project needs a policy

This tool creates new project data in an external system (Plane), which is a reversible write operation. The blast radius is medium because creating unwanted projects could clutter the system, consume resources, or cause confusion, but the action can be undone by deleting the project. It does not permanently destroy data, execute arbitrary code, or move money, so it does not warrant higher severity categories.

From the tool's definition Tool name 'create_plane_project' indicates creation of a new project resource. Description states 'Create a new project in the Plane project management system', which is a write operation that creates data and persists it.
