gsd_debug · Gsd MCP: Risk & Policy

WHAT IT DOES

What gsd_debug does on Gsd

AI agents invoke gsd_debug 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_debug needs a policy

Debugging tools typically execute code, run diagnostics, or interact with a running system. The mention of 'persistent state across context resets' indicates this tool writes/modifies state beyond a simple read operation. However, the description is vague, so confidence is moderate.

From the tool's definition 'Systematic debugging' and 'persistent state across context resets' — implies execution of diagnostic operations that modify or persist state

Verdict

gsd_debug Rate-limited

gsd_debug 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_debug

What does the gsd_debug tool do? +

Systematic debugging with persistent state across context resets. 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_debug? +

Register the Gsd MCP server in PolicyLayer and add a rule for gsd_debug: 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_debug? +

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

Can I rate-limit gsd_debug? +

Yes. Add a rate_limit block to the gsd_debug 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_debug completely? +

Set action: deny in the PolicyLayer policy for gsd_debug. 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_debug? +

gsd_debug 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.
