List all SLS projects in one or more Alibaba Cloud regions. Pass a single region string or an array of region IDs. If omitted, queries all regions configured in SLS_REGIONS / SLS_REGION env variables. Use this to discover available projects before querying logs.
AI agents call list_projects to retrieve information from Aliyun Sls without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves metadata about available Alibaba Cloud SLS projects across regions. While it performs no destructive or write operations, it has medium severity because enumerating cloud infrastructure projects could expose organizational structure or sensitive resource information to an attacker if credentials are compromised, though the blast radius is contained to information disclosure rather than data loss…
From the tool's definition Tool performs 'list' operation to retrieve SLS projects without modifying any data. Description states it 'List all SLS projects' and 'discover available projects' — classic read-only discovery.
Documented attack patterns abuse exactly the kind of access list_projects gives an agent:
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_projects:
{
"version": "1",
"default": "deny",
"tools": {
"list_projects": {}
}
}list_projects is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List all SLS projects in one or more Alibaba Cloud regions. Pass a single region string or an array of region IDs. If omitted, queries all regions configured in SLS_REGIONS / SLS_REGION env variables. Use this to discover available projects before querying logs. It is categorised as a Read tool in the Aliyun Sls MCP Server, which means it retrieves data without modifying state.
Register the Aliyun Sls MCP server in PolicyLayer and add a rule for list_projects: 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.
list_projects 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 list_projects 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 list_projects. 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.
list_projects 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.
Start from Aliyun Sls, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
