Check if the browser is connected and what data is available. Use this first to verify the bookmarklet is active.
AI agents call get_connection_status to retrieve information from Mcp Browser Lens without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves status information about browser connectivity and available data. It performs no writes, deletions, code execution, or financial operations. The purpose is diagnostic verification ('verify the bookmarklet is active'), making it a straightforward Read operation with minimal risk even if called inappropriately.
From the tool's definition Tool name 'get_connection_status' and description explicitly states 'Check if the browser is connected and what data is available' — a read-only query operation with no side effects.
Attacks that exploit this kind of access
Check if the browser is connected and what data is available. Use this first to verify the bookmarklet is active. It is categorised as a Read tool in the Mcp Browser Lens MCP Server, which means it retrieves data without modifying state.
Register the Mcp Browser Lens MCP server in PolicyLayer and add a rule for get_connection_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 Mcp Browser Lens. Nothing to install.
get_connection_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 get_connection_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 get_connection_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.
get_connection_status is provided by the Mcp Browser Lens MCP server (nano-step/mcp-browser-lens). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
