プロジェクト一覧を取得します
AI agents call list_projects to retrieve information from hokan MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves project information as a read-only operation. There are no side effects, no data modification, and no destructive actions. The Japanese description confirms it is a simple list/fetch operation (一覧を取得 = retrieve list). Severity is low because viewing project lists poses minimal risk even if an AI agent misuses it—at worst it gains visibility into existing projects.
From the tool's definition Tool name 'list_projects' and description 'プロジェクト一覧を取得します' (retrieves/fetches a list of projects) indicate a query operation that returns project data without modifying or deleting anything.
Attacks that exploit this kind of access
プロジェクト一覧を取得します. It is categorised as a Read tool in the hokan MCP Server MCP Server, which means it retrieves data without modifying state.
Register the hokan MCP Server MCP server in PolicyLayer and add a rule for list_projects: 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 hokan MCP Server. Nothing to install.
list_projects 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 list_projects 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 list_projects. 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.
list_projects is provided by the hokan MCP Server MCP server (shinonft/hokan-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
