account_info
Check your Rove account status including credit balance, plan tier, and API key info.
authenticate
Authenticate this MCP session by email. Sends a magic link to your inbox — click it to activate your session and get an API key. Required before using browser tools if no ROVE_API_KEY is set.
buy_creditswrite action
Get pricing information and purchase links for Rove credits. Returns Founder Pack tiers and top-up bundles with direct links to the pricing page.
click
Click an element on the page by CSS selector or accessible label. Use this to interact with buttons, links, checkboxes, and other clickable elements.
close_session
Close a browser session and release all associated resources (browser context, page, video recording). Returns a list of artifacts (screenshots, videos) captured during the session.
evaluatewrite action
Execute arbitrary JavaScript in the browser page context. Returns the result of the expression. Use for advanced DOM queries, custom extraction logic, or page manipulation.
extract_schema
Extract structured data from a webpage using a JSON schema. Navigates to the URL, waits for the page to load, and extracts values matching the schema keys from the page content. Returns a JSON object with the extracted data.
fill
Type text into a form field. By default clears any existing value first, then types the new value.
get_a11y_tree
Get the accessibility tree snapshot of the current page. Returns structured data 77% smaller than a screenshot. Auto-scopes to the main content area on large pages (50K+ chars). Use selector to manually scope to a specific element.
get_text
Extract the text content of an element on the page. Useful for reading specific values like prices, headings, or status messages.
interact
Perform a click or fill action on an element in the current browser session. Use "click" to click a button or link by CSS selector, or "fill" to type text into an input field.
list_sessions
Show the current active browser session for this MCP connection, including its URL, page title, and expiry.

Navigate a browser to a URL and return the page title, final URL, and accessibility tree snapshot. Automatically creates a new browser session if none exists. Returns structured data ideal for LLM consumption — 77% fewer tokens than screenshots.
screenshot
Capture a screenshot of the current browser page. Can take an in-session screenshot (using session_id) or a standalone screenshot of any URL. Returns the screenshot URL and metadata.

Why Accessibility Trees?

Traditional browser automation returns screenshots that cost ~114K tokens per page. Rove returns structured accessibility trees at ~26K tokens — 77% fewer tokens, faster responses, and better structured data for LLMs to reason over.
