列出所有Docker容器及其状态
AI agents call list_containers to retrieve information from WeChat Official Account MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool performs a read-only operation to enumerate and inspect Docker containers. It has no side effects, does not execute code or commands, does not modify data, and does not delete or move resources. While the information retrieved could be sensitive (revealing infrastructure details), the tool itself is fundamentally a data retrieval function with minimal blast radius for accidental misuse.
From the tool's definition Tool name is 'list_containers' and description states '列出所有Docker容器及其状态' (list all Docker containers and their status). This is a query operation that retrieves information about container states without modifying or executing anything.
Attacks that exploit this kind of access
列出所有Docker容器及其状态. It is categorised as a Read tool in the WeChat Official Account MCP Server MCP Server, which means it retrieves data without modifying state.
Register the WeChat Official Account MCP Server MCP server in PolicyLayer and add a rule for list_containers: 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 WeChat Official Account MCP Server. Nothing to install.
list_containers 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_containers 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_containers. 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_containers is provided by the WeChat Official Account MCP Server MCP server (jungley8/mcp4agent). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
