SDKs

Local CLI (stealth-cli)

The same Camoufox engine on your own machine — a CLI, a Node SDK, a background daemon, an HTTP server and an MCP server.

What it is

stealth-cli is the browser component the cloud platform runs, published on npm for local use. It launches Camoufox on your machine: browse, search, screenshot, extract and crawl from the terminal; drive it from Node; keep a daemon warm; expose it as an HTTP API or as an MCP server to a coding assistant. It talks to no cloud — nothing here needs a project API key.

cURL

npm install -g stealth-clinpx camoufox-js fetch        # downloads the Camoufox browser once

npm install -g stealth-cli
npx camoufox-js fetch        # downloads the Camoufox browser once

Node ≥ 20.

Commands

Command	What it does
`stealth browse <url>`	Visit a page and print it — `-f text`, `json`, `snapshot` (the accessibility tree with refs) or `markdown`
`stealth screenshot <url> -o page.png`	PNG or JPEG, full page or viewport; `--annotate` labels every interactive element with its ref
`stealth search <engine> <query>`	Search across 14 engines with anti-detection (`google`, `duckduckgo`, `youtube`, `github`, …)
`stealth extract <url>`	Links, images, meta, headings, CSS selectors
`stealth crawl <url>`	Recursive crawl with depth, filter and delay control
`stealth open [url]`	A headed browser for a human sign-in; exits when the windows close
`stealth interactive`	A stdin REPL: goto, click, type, eval, …
`stealth pdf <url>`, `batch <file>`, `monitor <url>`, `fingerprint`	PDF, batch, change monitoring, fingerprint check
`stealth daemon start\|stop\|status`	A background browser: ~1 s per command instead of ~6 s
`stealth profile`, `proxy`, `config`	Persistent identities, a proxy pool with rotation and health checks, global defaults
`stealth serve`	An HTTP API with bearer-token auth
`stealth mcp`	An MCP server

MCP server

Add stealth browsing to Claude Desktop, Cursor or any MCP client:

MCP client configuration

{  "mcpServers": {    "stealth": { "command": "stealth", "args": ["mcp"] }  }}

{
  "mcpServers": {
    "stealth": { "command": "stealth", "args": ["mcp"] }
  }
}

This is the local engine as an MCP server, not the cloud platform: it runs Camoufox on the machine the client runs on.

Node SDK

JavaScript

import { launchBrowser, closeBrowser, navigate, getMarkdown, takeScreenshot } from 'stealth-cli'; const handle = await launchBrowser({ profile: 'work', humanize: true });   // `stealth profile create work` firsttry {  await navigate(handle, 'https://example.com');  const { text } = await getMarkdown(handle, { maxChars: 20000 });  await takeScreenshot(handle, { path: 'labelled.png', annotate: true });} finally {  await closeBrowser(handle);}

import { launchBrowser, closeBrowser, navigate, getMarkdown, takeScreenshot } from 'stealth-cli';

const handle = await launchBrowser({ profile: 'work', humanize: true });   // `stealth profile create work` first
try {
  await navigate(handle, 'https://example.com');
  const { text } = await getMarkdown(handle, { maxChars: 20000 });
  await takeScreenshot(handle, { path: 'labelled.png', annotate: true });
} finally {
  await closeBrowser(handle);
}

The local SDK and the cloud SDKs share the observation and action vocabulary — refs, the tree, the same action names — so code written against one reads naturally against the other.
