Doppel MCP server

Read from the package source without running it. The installed server may list more.

• doppel_batch

  Apply a SEQUENCE of actions (click/type/press_key/hover) in ONE call, in order. PREFER THIS over separate click/type calls whenever you can already see the targets in the current snapshot - e.g. filling a form, ticking several checkboxes, or 'pick an option then click Continue'. Each separate tool call costs a full model round-trip; a batch is one. Refs come from the latest snapshot, so all target

• doppel_cleanup_tabs

  Close leftover Doppel automation tabs. By default only the generic 'Doppel' / 'Doppel Test' groups (debris from past sessions), leaving purpose-named task groups alone. Pass all:true to also close every purpose-named Doppel task group. Non-Doppel tabs and groups are never touched.

• doppel_click

  Click an element by its [ref] from the latest snapshot. Waits until it's actionable, then uses trusted native input. If you already know several actions from this snapshot, prefer doppel_batch to run them in one call.

• doppel_close_tab

  Close a tab Doppel controls and drop its session.

• doppel_console

  See the page's console output + JS errors, captured read-only. By default shows browser-level problems (errors, warnings, failed network/CSP/deprecation), which is fully stealthy. Page console.log/info is NOT captured unless you set `pageConsole:true`, which enables the CDP Runtime domain (detectable by a hostile page while on, so off by default; captures from that point forward). Uncaught JS exce

• doppel_hover

  Hover the mouse over an element by its [ref] (reveals menus/tooltips). Waits until it's actionable.

• doppel_list_tabs

  List the tabs Doppel controls (its tab group), with URLs and which is active.

• doppel_navigate

  Navigate the active tab: go to a URL, or go back/forward/reload. Waits for load. Returns the final URL plus a fresh page snapshot (by default).

• doppel_network

  See the page's network activity, captured read-only from the moment the tab attaches. Without `reqid`, returns a compact one-line-per-request list; pass `reqid` for full detail plus the response body. Successful static assets (images/fonts/scripts/css) are hidden unless `includeStatic`. Filter with `grep` (URL), `status`, `method`, `resourceType`, `failedOnly`, `xhrOnly` (just API calls), or `sinc

• doppel_new_tab

  Open a new tab (background, no focus stealing) and make it active. Optionally load a URL. Pass `group` to name the tab group by the task's purpose (e.g. '27in Monitor'); tabs sharing a group cluster together.

• doppel_press_key

  Press a special key (Enter, Tab, Backspace, Delete, Escape, Arrow keys) via trusted native input.

• doppel_screenshot

  Screenshot the current page (PNG by default). Returns the image. Prefer doppel_snapshot (text) when possible; use this only when you need to SEE pixels.

• doppel_scroll

  Scroll an element into view by its [ref] - e.g. to scroll to the last item of a list to trigger lazy-loading / infinite scroll, then re-snapshot. The snapshot already captures the whole page (all elements, on- or off-screen) and clicks auto-scroll into view, so use this only to trigger scroll-driven loading, not to 'see more'.

• doppel_select_tab

  Switch the active tab to another tab Doppel controls (tabId from doppel_list_tabs).

• doppel_set_group

  Name the current tab's group by the task's PURPOSE (e.g. '27in Monitor', 'Job Apply'), not the site. Call this at the start of a task so the group chip reads as what you're doing instead of 'Doppel'.

• doppel_snapshot

  Capture a structured accessibility snapshot of the current page. Elements are tagged with a [ref] for doppel_click/doppel_type; refs stay stable across grep/offset within a snapshot. Fast: no screenshot. On dense pages (search results, shopping) use interactive:true and/or grep to cut noise, and offset to page through results.

• doppel_status

  Check whether the Doppel browser extension is connected. Call this first if other tools error out.

• doppel_type

  Type text into an element by its [ref]. Waits until actionable, focuses it, and inserts trusted text (works with React/controlled inputs).

• doppel_uploadwrite action

  Upload local file(s) to a file input WITHOUT opening the native OS file dialog. Point `ref` at the upload control from a snapshot - the file input itself, or the button/label that opens it (Doppel finds the underlying <input type=file>). `path` is an absolute path on this machine; pass an array for a multi-file input. Fires the real change event, so the page reacts exactly as if a human picked the

• doppel_wait_for

  Wait until specific text appears on the page, or for a fixed time. Use after an action that loads content.
