Read from the source code; the running server may differ. Descriptions are the server’s own words; hidden characters are shown as [U+…].

• accept_eula

  CRITICAL: You MUST ask the user 'Do you accept the MCPBrowser EULA?' and wait for their explicit 'Yes' response BEFORE calling this tool. Set userExplicitlyConfirmed=true ONLY if the user explicitly said 'Yes' or 'I accept'. If the user has not responded or said 'No', DO NOT call this tool. Calling this tool without user consent violates the EULA terms.

• browser_click_elementClick Element

  Click buttons, links, or any element on a browser-loaded page. Use when: you need to navigate a website, submit a form, press a button, follow a link, or interact with any clickable UI element. Targets by CSS selector or visible text. Returns updated page HTML after click. PREREQUISITE: Page must be loaded with browser_fetch_webpage first.

• browser_close_tabClose Tabcan change or delete data

  Close a browser tab to free resources. Use when: you are done with a page and want to release memory, or need to reset session state for a hostname. Uses exact hostname match.

• browser_detect_formsDetect Formsread-only

  Scan a browser-loaded page and return all forms as structured JSON — fields, types, validation rules, submit buttons, and orphaned inputs. Use when: you need to understand a form before filling it, discover what fields exist on a page, or map form structure for automation. PREREQUISITE: Page must be loaded with browser_fetch_webpage first.

• browser_execute_javascriptExecute JavaScriptcan change or delete data

  Run JavaScript on a browser-loaded page and get the result. Use when: you need to extract structured data from a page, manipulate the DOM, read page state, run custom queries on page content, or perform UI actions that CSS selectors cannot reach. Returns the script result as JSON, text, or void. PREREQUISITE: Page must be loaded with browser_fetch_webpage first.

• browser_fetch_webpageFetch Web Pageread-only

  Load any URL and return its content using a real browser with full JavaScript execution. Use whenever a webpage needs to be loaded — whether to read content, interact with a web app, or access any HTTP/HTTPS resource. Connects to the user's existing browser session with all cookies, logins, and SSO sessions available automatically. Handles JavaScript rendering, authentication, and anti-bot protection. Prefer this over generic HTTP fetch for authenticated or JS-heavy pages.

• browser_get_current_htmlGet Current HTMLread-only

  Re-read HTML from an already-loaded page without reloading it. Use when: you need to check page state after a click or form fill, re-extract content from the current page, or get updated HTML after dynamic changes. Much faster than browser_fetch_webpage since it skips navigation. PREREQUISITE: Page must be loaded with browser_fetch_webpage first.

• browser_navigate_historyNavigate Back/Forward

  Go back or forward in browser history. Use when: you clicked a link and need to return to the previous page, or want to go forward after going back. PREREQUISITE: Page must be loaded with browser_fetch_webpage first.

• browser_plugin_actionPlugin Action

  Execute a site-specific plugin action on an already-open matching browser tab. Call browser_plugin_info first to discover available plugins and their actions, and use browser_fetch_webpage first when no matching site is open.

• browser_plugin_infoPlugin Inforead-only

  List available site-specific plugins and their actions. Use when: browser_fetch_webpage suggests a plugin in nextSteps, or you want to check what optimized actions are available for the current site. Call with no arguments to list all plugins, or with a plugin name for details.

• browser_scroll_pageScroll Page

  Scroll within a browser-loaded page. Automatically detects scrollable containers inside SPAs (e.g., ADO, Jira, Gmail) where the main content scrolls inside an inner div rather than the window. Use when: you need to see more content below the fold, bring an element into view before clicking, scroll to a specific section, or navigate long pages. Supports scroll by direction, to a CSS selector, or to absolute coordinates. PREREQUISITE: Page must be loaded with browser_fetch_webpage first.

• browser_take_screenshotTake Screenshotread-only

  Capture a screenshot of a browser-loaded page as PNG. Set fullPage=true to capture the entire scrollable page in one shot — this avoids multiple scroll+screenshot cycles. Only use fullPage=false when you specifically need just the current viewport (rare). Use when: you need to see what a page looks like, analyze visual layout, view charts/images/graphs, debug UI issues, or when HTML alone is insufficient. Returns base64-encoded PNG. PREREQUISITE: Page must be loaded with browser_fetch_webpage first.

• browser_type_textType Text

  Type text into input fields on a browser-loaded page. Use when: you need to fill a form, enter a search query, type into a text box, or input data into any editable field. Supports filling multiple fields in a single call. PREREQUISITE: Page must be loaded with browser_fetch_webpage first.

• compose_email

  Open Gmail compose window via keyboard shortcut and fill in email fields
