Run tests on BrowserStack. An agent skill from alirezarezvani/claude-skills.

  • Works in 5 steps: Configure for BrowserStack → Run Tests on BrowserStack → Get Build Results → …
  • User mentions browserstack
  • SKILL.md covers Prerequisites, Capabilities, MCP Tools Used and Output
  • Calls npm and npx; needs BROWSERSTACK_ACCESS_KEY

What it does

Browserstack is an agent skill from alirezarezvani/claude-skills. Run tests on BrowserStack. Use when user mentions "browserstack", "cross-browser", "cloud testing", "browser matrix", "test on safari", "test on firefox", or "browser compatibility".

Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Testing & QA, covering MCP servers. It works with Model Context Protocol, Playwright and npm. The repository describes itself as: 380 Claude Code skills & agent skills & plugins (30+ Agents, 70+ custom commands, 380+ skills, customizable references, scripts)for Claude Code, Codex, Gemini CLI, Cursor, and 8… The licence is MIT.

When your agent uses it

  • User mentions browserstack
  • Test on firefox
  • Browser compatibility

Example prompts

  • “browserstack”
  • “cross-browser”
  • “cloud testing”
  • “/browserstack”

Requirements

  • Node.js
  • A credential in BROWSERSTACK_ACCESS_KEY

Workflow steps

5 steps, taken from the step headings in SKILL.md.

  1. Configure for BrowserStack
  2. Run Tests on BrowserStack
  3. Get Build Results
  4. Check Available Browsers
  5. Local Testing

What it can do on your machine

Read from SKILL.md and the folder at commit 19392f7. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • npm
    • npx

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • browserstack.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • BROWSERSTACK_ACCESS_KEY

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Browserstack loads about 1.3k tokens when it runs. Until then it costs about 49 tokens; SKILL.md has 309 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~49
When it runs · the whole SKILL.md, loaded when a task matches
~1.3k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
Run tests on BrowserStack. Use when user mentions "browserstack", "cross-browser", "cloud testing", "browser matrix", "test on safari", "test on firefox", or "browser compatibility".

BrowserStack Integration

Run Playwright tests on BrowserStack's cloud grid for cross-browser and cross-device testing.

Prerequisites

Environment variables must be set:

  • BROWSERSTACK_USERNAME — your BrowserStack username
  • BROWSERSTACK_ACCESS_KEY — your access key

If not set, inform the user how to get them from browserstack.com/accounts/settings and stop.

The BrowserStack MCP server is not auto-registered (issue #978). pw-browserstack was removed from the plugin's .mcp.json because it failed to connect for every user (the plugin ships no node_modules). The browserstack_* MCP tools used below, and the /pw:browserstack command, will fail with "tool not found" until it is enabled manually — see the Integrations section of the plugin's CLAUDE.md (cd integrations/browserstack-mcp && npm install, then register the server in your own user/project MCP config). Setting the env vars alone is not sufficient.

Capabilities

1. Configure for BrowserStack
/pw:browserstack setup

Steps:

  1. Check current playwright.config.ts
  2. Add BrowserStack connect options:
typescript
// Add to playwright.config.ts
import { defineConfig } from '@playwright/test';

const isBS = !!process.env.BROWSERSTACK_USERNAME;

export default defineConfig({
  // ... existing config
  projects: isBS ? [
    {
      name: "chromelatestwindows-11",
      use: {
        connectOptions: {
          wsEndpoint: `wss://cdp.browserstack.com/playwright?caps=${encodeURIComponent(JSON.stringify({
            'browser': 'chrome',
            'browser_version': 'latest',
            'os': 'Windows',
            'os_version': '11',
            'browserstack.username': process.env.BROWSERSTACK_USERNAME,
            'browserstack.accessKey': process.env.BROWSERSTACK_ACCESS_KEY,
          }))}`,
        },
      },
    },
    {
      name: "firefoxlatestwindows-11",
      use: {
        connectOptions: {
          wsEndpoint: `wss://cdp.browserstack.com/playwright?caps=${encodeURIComponent(JSON.stringify({
            'browser': 'playwright-firefox',
            'browser_version': 'latest',
            'os': 'Windows',
            'os_version': '11',
            'browserstack.username': process.env.BROWSERSTACK_USERNAME,
            'browserstack.accessKey': process.env.BROWSERSTACK_ACCESS_KEY,
          }))}`,
        },
      },
    },
    {
      name: "webkitlatestos-x-ventura",
      use: {
        connectOptions: {
          wsEndpoint: `wss://cdp.browserstack.com/playwright?caps=${encodeURIComponent(JSON.stringify({
            'browser': 'playwright-webkit',
            'browser_version': 'latest',
            'os': 'OS X',
            'os_version': 'Ventura',
            'browserstack.username': process.env.BROWSERSTACK_USERNAME,
            'browserstack.accessKey': process.env.BROWSERSTACK_ACCESS_KEY,
          }))}`,
        },
      },
    },
  ] : [
    // ... local projects fallback
  ],
});
  1. Add npm script: "test:e2e:cloud": "npx playwright test --project='chrome@*' --project='firefox@*' --project='webkit@*'"
2. Run Tests on BrowserStack
/pw:browserstack run

Steps:

  1. Verify credentials are set
  2. Run tests with BrowserStack projects:
    bash
    BROWSERSTACK_USERNAME=$BROWSERSTACK_USERNAME \
    BROWSERSTACK_ACCESS_KEY=$BROWSERSTACK_ACCESS_KEY \
    npx playwright test --project='chrome@*' --project='firefox@*'
  3. Monitor execution
  4. Report results per browser
3. Get Build Results
/pw:browserstack results

Steps:

  1. Call browserstack_get_builds MCP tool
  2. Get latest build's sessions
  3. For each session:
    • Status (pass/fail)
    • Browser and OS
    • Duration
    • Video URL
    • Log URLs
  4. Format as summary table
4. Check Available Browsers
/pw:browserstack browsers

Steps:

  1. Call browserstack_get_browsers MCP tool
  2. Filter for Playwright-compatible browsers
  3. Display available browser/OS combinations
5. Local Testing
/pw:browserstack local

For testing localhost or staging behind firewall:

  1. Install BrowserStack Local: npm install -D browserstack-local
  2. Add local tunnel to config
  3. Provide setup instructions

MCP Tools Used

ToolWhen
browserstack_get_planCheck account limits
browserstack_get_browsersList available browsers
