AI agents call gsd_list_phases to retrieve information from Gsd without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns project phase data without altering state, executing code, or triggering external operations. It is a straightforward read operation on the GSD lifecycle framework's project roadmap, carrying minimal security risk.
From the tool's definition Tool name 'gsd_list_phases' and description 'List all phases from the roadmap' indicate a retrieval operation with no modification or side effects.
Attacks that exploit this kind of access
List all phases from the roadmap. It is categorised as a Read tool in the Gsd MCP Server, which means it retrieves data without modifying state.
Register the Gsd MCP server in PolicyLayer and add a rule for gsd_list_phases: 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.
gsd_list_phases is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the gsd_list_phases 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.
Set action: deny in the PolicyLayer policy for gsd_list_phases. 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.
gsd_list_phases 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.
