## What this connects

Browserless is a service that provides headless browser automation, allowing users to run automations on their own sites with browser infrastructure.

Vendor: https://browserless.io/

## Tools available

**7** tools available. First 7:

- `BROWSERLESS_DOWNLOAD_FILE` — Download file using Puppeteer script — This tool allows downloading files that Chrome has downloaded during the execution of puppeteer code. It sets up a blank page, creates a fresh download directory, injects the provided code, and executes it. Once the script finishes, any downloaded files from Chromium are returned with the appropriate content-type header.
- `BROWSERLESS_EXECUTE_CUSTOM_FUNCTION` — Execute Custom Function — A tool that allows executing custom Puppeteer scripts via HTTP requests. This endpoint enables users to run browser automation tasks without managing their own infrastructure.
- `BROWSERLESS_FETCH_HTML_CONTENT` — Fetch HTML Content — This tool fetches the complete HTML content of a webpage using Browserless's content API. It's designed to retrieve the full HTML contents of any website, including dynamically generated content.
- `BROWSERLESS_GENERATE_PDF` — Generate PDF from webpage — This tool generates a PDF from a specified webpage using browserless's PDF generation API. It allows specifying the URL of the webpage along with parameters such as format, filename, and waitUntil options to control the PDF generation process.
- `BROWSERLESS_SCRAPE_CONTENT` — Scrape webpage content using CSS selectors — A tool to extract structured content from a webpage by specifying CSS selectors. The tool navigates to the specified URL, waits for the page to load (including parsing and executing JavaScript), and returns the selected elements in a structured JSON format.
- `BROWSERLESS_TAKE_SCREENSHOT` — Take Screenshot — A tool that captures a screenshot of a webpage using browserless's screenshot API. The tool takes a URL and returns either a PNG or JPEG image. It includes options for full page capture, image type, quality, and clipping coordinates.
- `BROWSERLESS_UNBLOCK_PROTECTED_CONTENT` — Unblock Protected Content — This tool provides access to content from websites that implement bot protection mechanisms. It is designed to bypass various types of protection (such as CAPTCHA and bot detections) and return the HTML content of the protected webpage, with optional customization through parameters like waitFor, timeout, and stealth mode.

## How agents use Browserless

Inside a Definable workflow, Browserless is one of the tools the **Distributor specialist** can call. Example coordination patterns:

- **Researcher → Browserless** — the Researcher (GPT-5.5) pulls context from Browserless (records, threads, documents), synthesises findings, and briefs the rest of the team.
- **Writer → Distributor → Browserless** — the Writer (Claude Opus 4.7) drafts copy in brand voice, the Verifier passes it, then the Distributor writes the result into Browserless (create record, post message, draft email).
- **Designer / Engineer → Distributor → Browserless** — the Designer ships an asset or the Engineer ships a code change, the Distributor delivers it via Browserless (attach file, open PR comment, post status).

The Verifier checks every Browserless call. On rate limit, schema drift, or auth refresh it self-heals and retries — the workflow completes without manual intervention.
