gsd_discuss_phase · Gsd MCP: Risk & Policy

WHAT IT DOES

What gsd_discuss_phase does on Gsd

AI agents use gsd_discuss_phase 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_discuss_phase needs a policy

This tool writes project metadata (implementation decisions) to the GSD lifecycle state. It modifies the phase record by associating decisions with it, which is a reversible change. It does not execute external code, delete data, or trigger financial operations. The blast radius is limited to project planning metadata; miscapture would require correction but not cause system failure or data loss.

From the tool's definition Tool name 'gsd_discuss_phase' and description 'Capture implementation decisions before planning a phase' indicate the tool creates or records discussion/decision data associated with a project phase. The verb 'capture' implies data creation/modification.

Verdict

gsd_discuss_phase Rate-limited

gsd_discuss_phase 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.

PolicyLayer is an MCP gateway: every tool call is checked against your rule before it reaches Gsd, so you can run agents against it safely.

FAQ

Questions about gsd_discuss_phase

What does the gsd_discuss_phase tool do? +

Capture implementation decisions before planning a phase. 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_discuss_phase? +

Register the Gsd MCP server in PolicyLayer and add a rule for gsd_discuss_phase: 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_discuss_phase? +

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

Can I rate-limit gsd_discuss_phase? +

Yes. Add a rate_limit block to the gsd_discuss_phase 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_discuss_phase completely? +

Set action: deny in the PolicyLayer policy for gsd_discuss_phase. 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_discuss_phase? +

gsd_discuss_phase 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.
