AI agents call get_script_source 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.
This tool retrieves JavaScript source code for inspection and analysis purposes. While the empty description lowers confidence slightly, the tool name and server context (debugging, analyzing, reverse engineering) strongly suggest it performs read-only source code retrieval.
From the tool's definition Tool name 'get_script_source' and sibling tools 'list_scripts', 'list_breakpoints', 'get_paused_info' indicate data retrieval from the Chrome DevTools Protocol.
Documented attack patterns abuse exactly the kind of access get_script_source 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 get_script_source:
{
"version": "1",
"default": "deny",
"tools": {
"get_script_source": {}
}
}get_script_source is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

get_script_source. 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 get_script_source: 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.
get_script_source 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 get_script_source 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 get_script_source. 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.
get_script_source 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.
