## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 4 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 5 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## MCP tools (4)

### `browserless_content` (~168 tokens)

Render a URL in headless Chromium and return the fully-executed HTML (after JavaScript runs) — use this when a plain fetch returns an empty shell or JS-rendered SPA. Example: browserless_content({ url: "https://example.com", _apiKey: "your-token" })

Input parameters:

- `_apiKey` (string, required): Browserless API token (sign up at https://www.browserless.io/signup)
- `_host` (string): Optional region host override, default "https://production-sfo.browserless.io"
- `url` (string, required): The page URL to render, e.g. "https://example.com"
- `waitForTimeout` (number): Optional milliseconds to wait after load before capturing HTML (lets late JS settle), e.g. 3000

### `browserless_scrape` (~157 tokens)

Extract structured data from a rendered page using CSS selectors. Returns text, inner HTML, attributes and geometry for every matched element. Example: browserless_scrape({ url: "https://news.ycombinator.com", elements: [{ selector: ".titleline a" }], _apiKey: "your-token" })

Input parameters:

- `_apiKey` (string, required): Browserless API token (sign up at https://www.browserless.io/signup)
- `_host` (string): Optional region host override
- `elements` (array, required): Array of selector objects, each { selector: "<css-selector>" }. Uses document.querySelectorAll, so each selector can match many elements.
- `url` (string, required): The page URL to scrape

### `browserless_screenshot` (~157 tokens)

Capture a screenshot of a rendered page. Returns the image byte-length and metadata only (the binary PNG is NOT inlined). Example: browserless_screenshot({ url: "https://example.com", fullPage: true, _apiKey: "your-token" })

Input parameters:

- `_apiKey` (string, required): Browserless API token (sign up at https://www.browserless.io/signup)
- `_host` (string): Optional region host override
- `fullPage` (boolean): Capture the entire scrollable page instead of just the viewport (default false)
- `type` (string): Image format: "png" (default), "jpeg", or "webp"
- `url` (string, required): The page URL to screenshot

### `browserless_smart_scrape` (~216 tokens)

AI-assisted extraction: tries a plain HTTP fetch first and falls back to a full headless browser, returning content in the requested formats (html, markdown, links, screenshot, pdf). Best when you just want clean page content and do not know the right selectors. Example: browserless_smart_scrape({ url: "https://example.com", formats: ["markdown", "links"], _apiKey: "your-token" })

Input parameters:

- `_apiKey` (string, required): Browserless API token (sign up at https://www.browserless.io/signup)
- `_host` (string): Optional region host override
- `formats` (array): Which formats to return: any of "html", "markdown", "links", "screenshot", "pdf" (default ["html"]). "content" (raw HTML/parsed JSON) is always returned.
- `proxy` (string): Proxy pool: "residential" (default) or "datacenter"
- `url` (string, required): The page URL to extract
