列出所有定时任务
AI agents call cron_list 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 performs a query/list operation to retrieve metadata about scheduled tasks. It has no side effects, does not modify data, does not execute jobs, and does not delete anything. It is purely informational, making it a Read category tool with low severity since unauthorized access to job listings has limited direct impact compared to execution or deletion of jobs.
From the tool's definition Tool name 'cron_list' and description '列出所有定时任务' (list all scheduled tasks) indicate a read-only operation that retrieves information about existing cron jobs without modifying or executing them.
Attacks that exploit this kind of access
列出所有定时任务. 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_list: 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_list 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_list 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_list. 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_list 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.
