Tools & capabilities

Gecko MCP tools 41

  • list_tabsList all open tabs in Floorp (title, URL, browserId, and whether each is active or pinned). Use the browserId to target other tools.
  • open_tabOpen a URL in a new Floorp tab.
  • get_active_tabReturn the active tab's title, URL and browserId. Note: with multiple browser windows open, 'active' is ambiguous — prefer the browserId returned by open_tab, or pick from list_tabs.
  • navigate_tabNavigate a tab to a new URL. Targets the active tab unless a browserId is given.
  • close_tabClose a tab by its browserId (from list_tabs).
  • read_pageRead a tab's content. Returns clean Markdown by default; can also return raw HTML or the accessibility tree. Output is capped (default 25 KB) to protect the context — to LOCATE a specific element use `find` (cheaper) instead. Targets the active tab unless a browserId is given.
  • screenshotTake a screenshot of a tab and return it as a PNG image. Targets the active tab unless a browserId is given.
  • findLocate elements on a tab by visible text and/or tag and get a ready-to-use CSS `selector` for each — one fast call that searches the page server-side and returns ~1 KB instead of the whole HTML. Use this INSTEAD of read_page to find a button, link, or field, then pass the returned selector straight to click/type/etc. Provide `text`, `tag`, or both. Active tab unless browserId given.
  • clickClick an element by CSS selector OR by a `ref` (fingerprint) from `snapshot`. Auto-scrolls the element into view first (fixes off-screen 'not actionable'). Targets the active tab unless a browserId is given.
  • snapshotCapture a structured snapshot of a tab: clean Markdown with inline fingerprint refs (`<!--fp:...-->`) and an 'Element Selector Map' (fp | tag | text). Use this instead of read_page+grep to locate elements, then pass a `ref` to `click`. Targets the active tab unless a browserId is given.
  • type_textType text into an input or textarea by CSS selector (clears it first by default). Targets the active tab unless a browserId is given.
  • fill_formFill multiple form fields at once. `fields` maps CSS selectors (or field names) to values. Targets the active tab unless a browserId is given.

Webdriverio MCP tools 40

  • enable_toolsAdd a group of tools: `mocks`, `cookies`, `device`, `extensions`, `attach`, `elements`, `cloud-apps
  • start_sessionStart a browser, local Electron application, or mobile app session; `attach: true` retains the existing Chrome CDP connection mode
  • attach_sessionAttach to an existing remote WebDriver/Appium session by ID without creating a new session
  • launch_chromeLaunch a new Chrome instance with remote debugging enabled (for use with `start_session({ attach: true })`)
  • close_sessionClose or detach from the current session (supports `detach: true` to disconnect without terminating)
  • emulate_deviceEmulate a mobile/tablet device preset (viewport, DPR, UA, touch); requires BiDi session
  • open_web_extensionInstall a web extension through WebDriver BiDi and open one of its extension pages so normal page tools can drive its UI
  • navigateNavigate to a URL. In browsers the result shows the new page's interactive elements with refs
  • snapshotThe page as an accessibility tree with refs (`button "Save" [ref=e3]`), interactive elements by default (plain text is dropped, `full: true` shows it); pass refs to `perform_actions` for several steps; `find` returns only the parts containing a text (link targets included), `full: true` adds all te…
  • get_elementsGet visible, interactable elements with bounds. Supports `inViewportOnly` (default: true) and `includeContainers` (default: false). Mobile and Electron; listed after `enable_tools({ groups: ['elements'] })`, use `snapshot` first
  • get_accessibility_treeGet the accessibility tree with roles, names, and selectors. Electron-only; browsers use `snapshot
  • get_screenshotTake a screenshot of the current page or screen (base64-encoded, auto-resized to max 2000px / 1MB)
