获取调度器状态和运行信息
AI agents call cron_status to retrieve information from MCP Cron Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and reports the current status and runtime information of the scheduler. It performs no modifications, does not execute jobs, and has no side effects. It is purely informational, fitting the Read category. The low severity reflects minimal blast radius—even if an AI agent calls this repeatedly, it only gathers status data without affecting system operations or data.
From the tool's definition Tool name 'cron_status' and description '获取调度器状态和运行信息' (get scheduler status and runtime information) indicate a query operation that retrieves state information without modifying or executing jobs.
Attacks that exploit this kind of access
获取调度器状态和运行信息. It is categorised as a Read tool in the MCP Cron Server MCP Server, which means it retrieves data without modifying state.
Register the MCP Cron Server MCP server in PolicyLayer and add a rule for cron_status: 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 MCP Cron Server. Nothing to install.
cron_status 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 cron_status 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 cron_status. 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.
cron_status is provided by the MCP Cron Server MCP server (nolan57/opencode-mcp-cron). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
