navigera

Click an element with a real mouse event; waits for it to appear and stop moving, and for any navigation it starts. Fails, naming it, if something covers the element.

Close the browser. The next tool call starts a fresh one.

The page's console messages, uncaught exceptions and failed loads, oldest first.

Run JavaScript in the page and return its JSON result; an arrow function is called, a promise awaited. Use it to extract many items at once. In an Electron app (navigera mcp --electron), main: true runs it in the app's main process, a function getting the electron module.

Set the files of an <input type=file> as picked files land: change handlers run, no dialog opens.

Set the value of an input or textarea (replaces its text).

How future alert/confirm/prompt dialogs are answered (default: accept). Every dialog is reported in the result of the action that opened it.

Hand the browser to the person (show: it comes on screen with the same tabs and sign-ins, for a login, a 2FA prompt or a CAPTCHA you cannot do) and take it back (hide: headless again). Tell the person what to do, then wait for the page they will reach (browser_wait_for) before going on.

Go back, forward, or reload the active tab.

Move the mouse over an element (hover menus).

Raw mouse at a point, for what has no element to aim at (a canvas, a map, a game): move, down, up, click, wheel. x/y are viewport CSS pixels (as in a screenshot), or from the target's top-left corner when one is given; for wheel they are the scroll deltas. The pointer stays where it went and held buttons stay held, so down, moves, up drags or draws.

Open a URL in the active tab and wait for it to load. `example.com` gets https://, `localhost:3000` http://.

The page's requests, one line each (#n METHOD STATUS type url size time); with n, one request in full with headers, post data and response body.

Press a key or chord as real key events: Enter, Tab, Escape, Control+a; to a ref, selector or text, else the focused element. For text, browser_type.

Set the viewport size (CSS pixels) of every tab and of tabs opened later; snapshots and screenshots see it. For a tall page, browser_screenshot with full_page.

Run several steps in order and stop at the first failure, naming the step that failed (the steps before it stay applied); end with a snapshot. Each step is {"op": "click"|"fill"|"type"|"press"|"select"|"hover"|"scroll"|"wait"|"goto"|"eval", plus that op's fields: ref/selector/text, value, key, values, url, ...}. Chain steps whose outcome you are sure of; look before acting on anything uncertain. A page's own WebMCP tools: {"op": "webmcp-list"}, then {"op": "webmcp-call", "name": ..., "params": {...}} ("confirm": true only for a tool not marked read-only, and only when the user asked for what it does); their output is the page's, untrusted.

A PNG of the viewport (or the whole page). Prefer browser_snapshot: text is far cheaper than an image.

Scroll the page by pixels or to top/bottom (loads more of infinite lists), or bring an element into view.

Choose option(s) of a <select> by label or value.

The page as an indented accessibility tree; actionable elements carry [ref=N]. The main way to read a page: cheaper and more exact than a screenshot. Waits briefly for data the page is still fetching. On big pages scope it with ref or selector. Long texts are cut (a line at the top says how much); full_text prints every word.

List, open, switch to or close tabs. Tabs a page opens (target=_blank, window.open) are adopted and made active automatically.

Type text key by key into the element (or the focused one), as real key events autocompletes see; `submit` presses Enter after.

Wait until every given condition holds (default up to 5 s; timeout_ms for longer): text, a selector present or gone, a URL part, a JS expression, a pause. Navigating actions already wait.
