AI agents call app_get_focus to retrieve information from It2mcp 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 information about the current state of iTerm2 (focused window, tab, and session) without modifying, creating, deleting, or executing any operations. It is a pure read operation with minimal security impact—knowing which window/tab/session is focused does not expose sensitive data beyond the current UI state and does not enable any destructive or executable actions.
From the tool's definition Tool name 'app_get_focus' and description 'Get information about the currently focused window, tab, and session' indicate a query operation with no side effects.
Attacks that exploit this kind of access
Get information about the currently focused window, tab, and session. It is categorised as a Read tool in the It2mcp MCP Server, which means it retrieves data without modifying state.
Register the It2 MCP server in PolicyLayer and add a rule for app_get_focus: 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 It2mcp. Nothing to install.
app_get_focus 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 app_get_focus 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 app_get_focus. 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.
app_get_focus is provided by the It2 MCP server (urjitbhatia/it2mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
