gsd_ship · Gsd MCP: Risk & Policy

WHAT IT DOES

What gsd_ship does on Gsd

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

WHY IT NEEDS A POLICY

Why gsd_ship needs a policy

Creating a PR is a reversible write operation—the PR can be closed or the branch deleted without permanent data loss. It does not execute arbitrary code, delete data irreversibly, or move money. However, it has medium severity because a malicious PR could inject malicious code into a codebase, trigger CI/CD pipelines, or create social engineering vectors if an AI agent is tricked into shipping inappropriate changes.

From the tool's definition Tool name 'gsd_ship' and description 'Create a PR from completed phase work' indicate the tool creates a pull request, which is a write operation that creates new data (the PR artifact) in a version control system.
