Monitor WebSocket connections and messages
AI agents call monitor_websockets to retrieve information from Pydoll without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Monitoring WebSocket connections retrieves and observes network traffic and message data without altering state, executing code, or triggering external side effects. However, severity is elevated to medium because (1) access to WebSocket message content could expose sensitive data if the agent misuses this capability to spy on confidential communications, and (2) in the context of a browser automation tool with…
From the tool's definition Tool is named 'monitor_websockets' with description 'Monitor WebSocket connections and messages' — the verbs 'monitor' and 'messages' indicate passive observation and data retrieval without modification or execution of external operations.
Documented attack patterns abuse exactly the kind of access monitor_websockets gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Pydoll, and nothing reaches the server without passing your rules. This is the rule we recommend for monitor_websockets:
{
"version": "1",
"default": "deny",
"tools": {
"monitor_websockets": {}
}
}monitor_websockets is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Monitor WebSocket connections and messages. It is categorised as a Read tool in the Pydoll MCP Server, which means it retrieves data without modifying state.
Register the Pydoll MCP server in PolicyLayer and add a rule for monitor_websockets: 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 Pydoll. Nothing to install.
monitor_websockets 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 monitor_websockets 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 monitor_websockets. 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.
monitor_websockets is provided by the Pydoll MCP server (jinsongroh/pydoll-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Pydoll, 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.
