Cloak Browser MCP

Generate Playwright-style locator code for an element by ref. Useful for codegen.

Print resolved server config (capabilities, profile, proxy, fingerprint, allow/block lists).

Respond to the next dialog (alert/confirm/prompt/beforeunload).

Remove highlight from a previously highlighted element, or all of them.

Persistently outline an element so a human reviewer can see what the agent picked.

Hover over an element.

Clear localStorage on the active page.

Remove a localStorage key.

Read a localStorage value.

List all localStorage entries.

Set a localStorage key on the active page.

Click at pixel coordinates (bypasses accessibility tree).

Press a mouse button at the current cursor position.

Drag from one coordinate pair to another.

Move the cursor to pixel coordinates.

Release a mouse button at the current cursor position.

Scroll via mouse wheel by delta pixels.

Load a URL in the active tab. Returns a fresh snapshot after navigation.

Go back one entry in the active tab's history.

Inspect a single captured request by index (from browser_network_requests).

List captured HTTP requests for the active tab since last navigation.

Toggle online/offline simulation for the active context.

Save the current page as PDF (Chromium-only).

Send a single key or key combination at page level.

Resize the viewport.

Resume page execution if paused via debugger; statement or DevTools breakpoint.

Install a request mock. Matched requests are fulfilled with the given status/body/headers.

List active request mocks.

Execute arbitrary JS in the server process. Only available when started with BOTH --caps config AND --enable-unsafe-eval.

Scroll the page or an element by a pixel amount.

Select one or more options in a <select> dropdown.

Clear sessionStorage on the active page.

Remove a sessionStorage key.

Read a sessionStorage value.

List all sessionStorage entries.

Set a sessionStorage key on the active page.

Import cookies + origin storage from a JSON file. Applied at context boot, so requires --profile-dir to persist beyond this session.

Capture an accessibility-tree snapshot of the active page. Returns a structured outline with [eN] refs you can pass to interaction tools.

Start recording actions that the user performs in the browser as Playwright code. Use it when the user wants to demonstrate a flow manually. Call browser_stop_recording when the user says they are done to retrieve the recorded actions.

Begin a Playwright trace recording. Stop with browser_stop_tracing to write the .zip.

Begin a video recording. Stop with browser_stop_video. Note: video must be configured at context creation; for ephemeral sessions, the next launched tab is recorded.

Stop the recording started with browser_start_recording and return the recorded actions as Playwright code.

Stop tracing and write the .zip trace to the path passed in browser_start_tracing.

Stop the video recording flag.

Export cookies + origin storage to a JSON file.

List, create, switch between, or close tabs.

Capture a screenshot of the page or a specific element.

Type text into an editable field. Use --humanize for natural per-character timing.

Remove a route mock (or all mocks if pattern is omitted).

Assert that an element matching role+accessible name is visible.

Assert that a list element exists and contains each item.

Assert that text is visible on the page.

Assert an input value or computed state.

Insert a chapter marker into the video buffer (no-op when video is off).

Stop annotating actions performed on the page.

Annotate subsequent actions performed on the page with a callout that names the action and, when styled, marks the action point and highlights the target element. Useful while video recording or screencasting.

Wait for time, text appearance/disappearance, or selector state.

Report installed CloakBrowser binary version, tier (free or pro), platform, and cache path.

Force CloakBrowser to check for and download the latest Chromium build. May take several minutes (~200MB).

Load a well-known bot-detection probe page and dump its key result fields.

Toggle humanized mouse/keyboard inputs and tune behavior. Takes effect on subsequent click/type calls when --caps humanize is on.

Create a fresh persistent profile directory under ~/.cloak-browser-mcp/profiles/<name>. Use as --profile-dir on next launch.

Delete a profile directory. Requires confirm=true. The active session is unaffected.

List all profile directories under ~/.cloak-browser-mcp/profiles/.

Open the target URL in an ephemeral background tab and capture per-request connection signals: response status, security details (TLS protocol/issuer), response headers, and request headers (Accept-Language, User-Agent, Sec-CH-UA-*).

Apply a fingerprint profile to the active context. Some fields (seed, GPU, screen) require recreating the context — current pages will be reopened on the same URL.

Set the geolocation reported by navigator.geolocation. Pass fromProxyIp=true to auto-resolve from proxy exit IP.

Override navigator.language and Accept-Language for the active context.

Replace the current proxy. This recreates the BrowserContext (state is preserved if --profile-dir was used; otherwise cookies are lost).

Live-override the timezone for the active context via CDP (no relaunch).

Programmatic stealth audit. Reports navigator.webdriver, plugin count, WebGL vendor/renderer, languages, user agent, hardwareConcurrency, deviceMemory, permissions, chrome.runtime presence, and a canvas fingerprint hash.
