Part of the DataGen server.

listSchedules is read-only, but an agent in a loop can still rack up calls and cost. PolicyLayer caps every call before it runs. Live in minutes.

AI agents call listSchedules to retrieve information from DataGen without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.

Even though listSchedules only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.

Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

Every attack above starts with a tool call. PolicyLayer checks each one against your policy first, so listSchedules only ever does what you allow.

What does the listSchedules tool do? +

List all scheduled deployments for the current user. View and manage all your scheduled deployment executions with filtering and pagination options. Perfect for: - Getting an overview of all scheduled tasks - Finding specific schedules by deployment or status - Managing and monitoring scheduled executions - Planning workflow timing and coordination Returns: - List of all schedules with details - Schedule status and next execution times - Deployment information and input variables - Pagination support for large lists. It is categorised as a Read tool in the DataGen MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on listSchedules? +

Register the DataGen MCP server in PolicyLayer and add a rule for listSchedules: 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 DataGen. Nothing to install.

What risk level is listSchedules? +

listSchedules is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit listSchedules? +

Yes. Add a rate_limit block to the listSchedules 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.

How do I block listSchedules completely? +

Set action: deny in the PolicyLayer policy for listSchedules. 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.

What MCP server provides listSchedules? +

listSchedules is provided by the DataGen MCP server (kuoyusheng/datagendev). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every DataGen tool call.
