gsd_spike · Gsd MCP: Risk & Policy

WHAT IT DOES

What gsd_spike does on Gsd

AI agents invoke gsd_spike to trigger actions in Gsd. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why gsd_spike needs a policy

A 'spike' in software development terminology means running quick, experimental code or prototypes to explore feasibility. This suggests executing throwaway experiments rather than just reading or writing persistent data. The description is vague, lowering confidence, but the most likely interpretation is Execute.

From the tool's definition 'Rapidly spike an idea with throwaway experiments' — implies running/executing experimental code or operations

Verdict

gsd_spike Rate-limited

gsd_spike stays usable, but rate-capped — a runaway agent can't fire it dozens of times 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_spike

What does the gsd_spike tool do? +

Rapidly spike an idea with throwaway experiments. It is categorised as a Execute tool in the Gsd MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on gsd_spike? +

Register the Gsd MCP server in PolicyLayer and add a rule for gsd_spike: 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_spike? +

gsd_spike is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit gsd_spike? +

Yes. Add a rate_limit block to the gsd_spike 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_spike completely? +

Set action: deny in the PolicyLayer policy for gsd_spike. 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_spike? +

gsd_spike 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.
