Get scheduler status and running tasks.
AI agents call claudecron_scheduler_status to retrieve information from Email MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries the state of a scheduler and lists active tasks. It retrieves data with no side effects, mutations, or external operations triggered. It falls squarely into the Read category. Severity is low because exposing scheduler status poses minimal security risk unless the task details reveal sensitive information, but the tool itself performs no dangerous actions.
From the tool's definition Tool name includes 'status' and description states 'Get scheduler status and running tasks' — both indicate retrieval of information without modification.
Attacks that exploit this kind of access
Get scheduler status and running tasks. It is categorised as a Read tool in the Email MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Email MCP Server MCP server in PolicyLayer and add a rule for claudecron_scheduler_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 Email MCP Server. Nothing to install.
claudecron_scheduler_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 claudecron_scheduler_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 claudecron_scheduler_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.
claudecron_scheduler_status is provided by the Email MCP Server MCP server (sventern/mcp_email). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
