Lists all available targets (WebView threads, AppService threads, etc.) in the connected debugger.
AI agents call list_targets to retrieve information from MiniApp CDP MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool performs information discovery on the debugger state—enumerating available threads and targets. While it is part of a reverse-engineering toolkit, the tool itself only retrieves metadata about what debugging sessions are active. It has no side effects, cannot modify state, and does not execute code.
From the tool's definition Tool name 'list_targets' and description state it 'Lists all available targets (WebView threads, AppService threads, etc.) in the connected debugger.' This is purely a read operation that queries and retrieves information about debugging targets without…
Documented attack patterns abuse exactly the kind of access list_targets gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and MiniApp CDP MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for list_targets:
{
"version": "1",
"default": "deny",
"tools": {
"list_targets": {}
}
}list_targets is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Lists all available targets (WebView threads, AppService threads, etc.) in the connected debugger. It is categorised as a Read tool in the MiniApp CDP MCP MCP Server, which means it retrieves data without modifying state.
Register the MiniApp CDP MCP server in PolicyLayer and add a rule for list_targets: 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 MiniApp CDP MCP. Nothing to install.
list_targets 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_targets 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_targets. 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_targets is provided by the MiniApp CDP MCP server (zhizhuodemao/miniapp-cdp-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
