gsd_phase_complete · Gsd MCP: Risk & Policy

WHAT IT DOES

What gsd_phase_complete does on Gsd

AI agents use gsd_phase_complete 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_phase_complete needs a policy

This tool creates or modifies data reversibly (Write category). Marking a phase complete changes project metadata and state but does not delete data or execute arbitrary code. It affects project management state, making it medium severity — an AI misusing it could incorrectly advance phases, delaying or disrupting project workflows, but the action can typically be reversed by unmarking or reopening the phase.

From the tool's definition Tool name and description indicate it 'Mark a phase as complete and update roadmap' — this modifies project state by transitioning a phase to a completed status and updating associated roadmap data.

Verdict

gsd_phase_complete Rate-limited

gsd_phase_complete 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.

FAQ

Questions about gsd_phase_complete

What does the gsd_phase_complete tool do? +

Mark a phase as complete and update roadmap. It is categorised as a Write tool in the Gsd MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on gsd_phase_complete? +

Register the Gsd MCP server in PolicyLayer and add a rule for gsd_phase_complete: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Gsd. Nothing to install.

What risk level is gsd_phase_complete? +

gsd_phase_complete is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit gsd_phase_complete? +

Yes. Add a rate_limit block to the gsd_phase_complete rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block gsd_phase_complete completely? +

Set action: deny in the PolicyLayer policy for gsd_phase_complete. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides gsd_phase_complete? +

gsd_phase_complete is provided by the Gsd MCP server (m0-ar/gsd-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
