ツール

Navigate to a URL in the active browser tab

Click an element on the page using a ref from snapshot or a CSS selector

Type text into an input element

Scroll the page or an element. Supports pixel offsets, scrolling to elements, and named positions (top/bottom). Works with virtual scroll containers used by social media sites.

Press a keyboard key or combination (Enter, Escape, Tab, ArrowDown, etc). Supports modifiers like Ctrl+A, Cmd+C.

Wait for a condition: element to appear, element to disappear, or a fixed delay. Useful for SPAs and dynamic content.

Get an accessibility tree snapshot of the page. Returns element refs you can use with click, type, and other tools. Use compact mode (default) for smaller output - only interactive elements.

Capture a screenshot of the visible page area

Read console messages (log, warn, error) from the browser

Read network requests made by the page. Filter by URL pattern.

Manage browser tabs: list, create, close, or focus

Find elements on the page using natural language (e.g. "login button", "search input"). Returns refs you can use with click/type.

Extract raw text content from the page or a specific element

Hover over an element to trigger tooltips, dropdown menus, or hover states

Select an option from a dropdown/select element

Execute JavaScript in the page and return the result. Use for DOM queries, reading page state, or any operation not covered by other tools.

Click an element by its visible text content. Works on React dropdowns, portals, and overlays that may not appear in snapshots. CSP-safe (no eval). Prefers deepest matching element.

Handle JavaScript dialogs (alert, confirm, prompt). Dialogs block page interaction until handled.

概要

What is Real Browser MCP?

Real Browser MCP is an MCP server paired with a Chrome extension that gives AI coding agents (Cursor, Claude, Windsurf) direct access to your actual browser — the one you already have open with all your sessions, logins, and cookies. Unlike tools that launch a fresh headless browser, it interacts with your existing browser environment.

How to use Real Browser MCP?

Install the server globally via npx real-browser-mcp and install the companion Chrome extension from the Chrome Web Store. No further configuration is needed to start controlling your browser with AI agent prompts.
