Deploy serverless browser automation as cloud functions using Browserbase. Use when the user wants to deploy browser automation to run on a schedule or cron, create a webhook endpoint for browser tasks, run automation in the cloud instead of locally, or asks about Browserbase Functions.

Deploy serverless browser automation using the official browse CLI.
Get an API key from: https://browserbase.com/settings
export BROWSERBASE_API_KEY="your_api_key"
browse functions init my-function
cd my-function
This creates:
my-function/
├── package.json
├── index.ts # Your function code
└── .env # Add credentials here
echo "BROWSERBASE_API_KEY=$BROWSERBASE_API_KEY" >> .env
pnpm install
import { defineFn } from "@browserbasehq/sdk-functions";
import { chromium } from "playwright-core";
defineFn("my-function", async (context) => {
const { session, params } = context;
// Connect to browser
const browser = await chromium.connectOverCDP(session.connectUrl);
const page = browser.contexts()[0]!.pages()[0]!;
// Your automation
await page.goto(params.url || "https://example.com");
const title = await page.title();
// Return JSON-serializable result
return { success: true, title };
});
Key objects:
context.session.connectUrl - CDP endpoint to connect Playwrightcontext.params - Input parameters from invocationbrowse functions dev index.ts
Server runs at http://127.0.0.1:14113
curl -X POST http://127.0.0.1:14113/v1/functions/my-function/invoke \
-H "Content-Type: application/json" \
-d '{"params": {"url": "https://news.ycombinator.com"}}'
The dev server auto-reloads on file changes. Use console.log() for debugging - output appears in the terminal.
browse functions publish index.ts
Output:
Function published successfully
Build ID: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
Function ID: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
Save the Function ID - you need it to invoke.
| Command | Description |
|---|---|
browse functions init <name> | Create new project |
browse functions dev <file> | Start local dev server |
browse functions publish <file> | Deploy to Browserbase |

Analyze an existing web application, identify safe user-visible capabilities across routes, forms, server actions, handlers, and schemas, then implement first-party WebMCP tools and validate discovery and invocation with Stagehand. Use when the user asks to make a codebase agent-ready, expose website features as WebMCP tools, or add WebMCP directly to an app rather than generating a standalone injection script from a URL.

Audit the developer experience of a product, SDK, docs site, or SKILL.md by dropping multiple Claude subagents at it with only a tiny task prompt and real tools (WebFetch, Bash, Write). Agents must discover the docs themselves, install deps, ask for credentials if needed, and attempt real execution. The skill captures each agent's trace — tool calls, retries, wall time, errors — and scores on Setup Friction, Speed, Efficiency, Error Recovery, and Doc Quality, then emits an HTML report with an A–F grade and concrete fixes. Use when the user asks to audit agent experience, test a skill, audit docs for agents, check if a SDK is agent-friendly, validate a SKILL.md, measure agent DX, or benchmark how painful onboarding is for an AI agent. Triggers: 'audit agent experience', 'test this skill', 'audit docs for agents', 'is my SDK agent-friendly', 'run a DX audit', 'agent experience test', 'test my docs', 'how do agents do with my product'.

Self-improving browser automation via the auto-research loop. Iteratively runs a browsing task, reads the trace, and improves the navigation skill (strategy.md) until it reliably passes. Supports parallel runs across multiple tasks using sub-agents. Use when you want to build or improve browser automation skills for specific website tasks.

Automate web browser interactions using natural language via CLI commands. Use when the user asks to browse websites, navigate web pages, extract data from websites, take screenshots, fill forms, click buttons, or interact with web applications. Supports remote Browserbase sessions with Browserbase Identity, Verified browsers, automatic CAPTCHA solving, and residential proxies — ideal for protected websites and JavaScript-heavy pages.

Turn a website's observable HTTP traffic into a best-effort OpenAPI 3.1 spec by analyzing a `browser-trace` capture. Use when the user wants to discover/extract API endpoints from a browser session, build an OpenAPI doc from network traffic, or document a third-party site's XHR/fetch surface for client integration.

Capture a full DevTools-protocol trace of any browser automation — CDP firehose, screenshots, and DOM dumps — then bisect the stream into per-page searchable buckets. Use when the user wants to debug a failed run, audit network/console/DOM activity, attach a trace to an in-progress session, or feed structured per-page summaries back into an agent loop so its next iteration learns from the last one.
