AI agents invoke run_cdp to trigger actions in DrissionPageMCP. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.
This tool allows execution of arbitrary CDP commands with user-supplied arguments, giving an AI agent direct control over browser internals. CDP commands can execute JavaScript, modify page content, intercept requests, exfiltrate data, or trigger downloads with no inherent restrictions. The blast radius is critical because CDP access is equivalent to full browser compromise.
From the tool's definition run_cdp accepts arbitrary Google Chrome DevTools Protocol (CDP) commands ('cmd: CDP协议命令') and executes them on the current browser tab ('在当前标签页中运行谷歌CDP协议代码').
Documented attack patterns abuse exactly the kind of access run_cdp gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and DrissionPageMCP, and nothing reaches the server without passing your rules. This is the rule we recommend for run_cdp:
{
"version": "1",
"default": "deny",
"tools": {
"run_cdp": {
"limits": [
{
"counter": "run_cdp_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}run_cdp stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

It is categorised as a Execute tool in the DrissionPageMCP MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the DrissionPage MCP server in PolicyLayer and add a rule for run_cdp: 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 DrissionPageMCP. Nothing to install.
run_cdp is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the run_cdp 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 run_cdp. 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.
run_cdp is provided by the DrissionPage MCP server (wxhzhwxhzh/drissionpagemcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
