Web automation · macOS · Windows

Effect: write (strongest supported action). Status: gated.

Gated means the tool requires an installed app, a connected account, permission, or runtime availability. Check those requirements on the listed platform before using it.

macOS

Purpose

Brings a web session's browser window to the FRONT so the USER can take over directly — solve a CAPTCHA, complete 2FA, or make a choice the AI shouldn't. Local MCP never solves CAPTCHAs itself; this hands control to the user. Pair with web_screenshot first to show them what's on the page. After they finish, tell the agent to continue — the session keeps its state.

Required inputs

No required inputs are declared in this platform's schema. Optional selectors and runtime requirements may still apply.

Permissions and confirmation

No explicit confirmation parameter is exposed in this snapshot. This does not grant permission to act: obtain user authorization before any real action.

Use only the apps, accounts and resources authorized by the user on this platform. Consult this tool's platform-specific description for its connection and permission requirements; this catalog does not assert additional OAuth scopes or OS entitlements.
