create_project_card · Mcp Github MCP: Risk & Policy

WHAT IT DOES

What create_project_card does on Mcp Github

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

WHY IT NEEDS A POLICY

Why create_project_card needs a policy

The tool creates new project management data within GitHub. This is a Write-category action because it creates a new resource (project card) that can be modified or deleted later. Severity is medium because misuse could clutter project boards or create confusion, but the impact is limited to project organization metadata and is fully reversible.

From the tool's definition Tool description states 'Create a new card in a project column' — this creates a new entity (card) in GitHub's project management system, a reversible operation.
