List all scheduled tasks.
AI agents call claudecron_list_tasks 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 is fundamentally a Read operation as it retrieves and queries scheduled task information without creating, modifying, or deleting data. The severity is medium rather than low because: (1) scheduled tasks in an email context may reveal sensitive automation patterns, (2) the server handles multiple email accounts with encryption, and (3) listing all tasks could expose account structure and operational details to…
From the tool's definition Tool name contains 'list' and description states 'List all scheduled tasks' - a data retrieval operation with no modification.
Attacks that exploit this kind of access
List all scheduled 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_list_tasks: 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_list_tasks 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_list_tasks 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_list_tasks. 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_list_tasks 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.
