THE RISK

Low Risk

Why list_logstores needs a policy

This tool retrieves and enumerates logstores available in an SLS project. It is a read-only operation that has no side effects, does not execute code or commands, does not modify data, and does not involve financial transactions. The discovery capability is informational only. Severity is low because listing available resources poses minimal risk even if called inappropriately by an AI agent.

From the tool's definition Tool name 'list_logstores' and description 'List all logstores within an SLS project' indicate a query/discovery operation with no data modification or execution of commands.

POLICY

How to control list_logstores

PolicyLayer is an MCP gateway — it sits between your AI agents and Aliyun Sls, and nothing reaches the server without passing your rules. This is the rule we recommend for list_logstores:

policy.json

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

list_logstores is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register Aliyun Sls — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

How do I enforce a policy on list_logstores? +

Register the Aliyun Sls MCP server in PolicyLayer and add a rule for list_logstores: 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 Aliyun Sls. Nothing to install.

What risk level is list_logstores? +

Can I rate-limit list_logstores? +

Yes. Add a rate_limit block to the list_logstores 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_logstores completely? +

What MCP server provides list_logstores? +

list_logstores is provided by the Aliyun Sls MCP server (suxyee/aliyun-sls-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Aliyun Sls tool call.

Start from Aliyun Sls, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
