gsd_new_milestone · Gsd MCP: Risk & Policy

WHAT IT DOES

What gsd_new_milestone does on Gsd

AI agents use gsd_new_milestone 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_new_milestone needs a policy

This tool creates a new milestone, which is a Write operation (creating new data). It is reversible in the sense that milestones can typically be removed or modified. Severity is medium because creating a spurious or incorrect milestone could disrupt project tracking and workflow, but it does not irreversibly destroy data.

From the tool's definition 'Start a new milestone' — creates a new milestone entity in the GSD project lifecycle

Verdict

gsd_new_milestone Rate-limited

gsd_new_milestone stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
