Browser pool status
AI agents call pool_status to retrieve information from Browser Pool without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or queries the status of the browser pool—a read-only operation with no side effects. It falls clearly into the Read category as it neither creates, modifies, deletes, executes code, nor involves financial operations. The severity is low because retrieving status information poses minimal risk of misuse by an AI agent.
From the tool's definition Tool name 'pool_status' and description 'Browser pool status' indicate a query/status retrieval operation that returns information about the state of the browser pool without modifying any resources or executing operations.
Attacks that exploit this kind of access
Browser pool status. It is categorised as a Read tool in the Browser Pool MCP Server, which means it retrieves data without modifying state.
Register the Browser Pool MCP server in PolicyLayer and add a rule for pool_status: 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 Browser Pool. Nothing to install.
pool_status 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 pool_status 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 pool_status. 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.
pool_status is provided by the Browser Pool MCP server (omgeverdo/browser-pool-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
