WHAT IT DOES

What list_checkpoints does on Mcp Control Plane

AI agents call list_checkpoints to retrieve information from Mcp Control Plane without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why list_checkpoints is rated Low

This tool retrieves and enumerates checkpoint models available to ComfyUI and SDXL runners. It performs data discovery without modifying, executing, or deleting any resources. The information returned may help an agent understand available ML models, but misuse carries minimal risk—the worst outcome is wasted context or incorrect model selection, not data loss or code execution.

From the tool's definition Tool name 'list_checkpoints' and description 'List installed checkpoint models' indicate a query/retrieval operation with no side effects. The verb 'list' is a canonical Read operation.

RECOMMENDED RULE

The rule that runs list_checkpoints safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Mcp Control Plane, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For list_checkpoints, this is the rule to start with:

list_checkpoints Allowed

list_checkpoints is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "list_checkpoints": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Mcp Control Plane, apply this rule, and every list_checkpoints call is checked against it from then on.

How do I enforce a policy on list_checkpoints? +

Register the Mcp Control Plane MCP server in PolicyLayer and add a rule for list_checkpoints: 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 Control Plane. Nothing to install.

What risk level is list_checkpoints? +

Can I rate-limit list_checkpoints? +

Yes. Add a rate_limit block to the list_checkpoints 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 list_checkpoints completely? +

Set action: deny in the PolicyLayer policy for list_checkpoints. 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 list_checkpoints? +

list_checkpoints is provided by the Mcp Control Plane MCP server (albertik322-sudo/mcp-control-plane). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
