## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, 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)

Scored 2026-11-05.

- **Endpoint Security**: 57/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation check failed: no authorisation is required to call this server, and it exposes a tool marked destructive (browser_act).
  - HTTPS is enforced; there's no plaintext access path.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 77/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 888 tokens (~148/item across 6 items; 6 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 30/100
  - Stability observed for 9 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 6 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 6 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 (6)

### `browser_navigate` (~175 tokens)

Navigate to a URL

Use for: loading a web page in a real Chromium browser and reading it. Returns the page title, final URL and a clean text extract (up to 8000 chars). Don't use when: you only need raw HTML or an API response — a plain HTTP fetch is cheaper. Errors are structured: NAV_TIMEOUT, NAV_FAILED, INVALID_URL. Paid: $0.005 per call via x402 (Base USDC, Solana USDC, or XRPL XRP).

Input parameters:

- `session_id` (string, required): Session ID. Reuse the same ID to keep cookies, login state and page position across calls; a new ID starts a fresh browser.
- `url` (string, required): Absolute http(s) URL to load.
- `wait_for` (string): Optional CSS selector to wait for after load (max 10s).

Output parameters:

- `session_id` (string)
- `text` (string)
- `title` (string)
- `url` (string)

### `browser_extract` (~169 tokens)

Extract data from the current page

Use for: pulling repeated elements (prices, titles, links) from the page a session is on, via a CSS selector, or the full page text when no selector is given. Returns one string per matched element. Don't use when: the page has not been loaded yet — call browser_navigate first. Paid: $0.005 per call via x402 (Base USDC, Solana USDC, or XRPL XRP).

Input parameters:

- `attribute` (string): Attribute to read instead of text, e.g. href or src.
- `selector` (string): CSS selector to extract. Omit for full page text.
- `session_id` (string, required): Session ID. Reuse the same ID to keep cookies, login state and page position across calls; a new ID starts a fresh browser.

Output parameters:

- `count` (number)
- `results` (array)

### `browser_snapshot` (~132 tokens)

Accessibility snapshot of the current page

Use for: understanding page structure cheaply and deterministically — returns the accessibility tree (roles, names, states) as compact YAML instead of pixels or raw HTML. This is the lowest-token way to decide what to click or fill next. Don't use when: you need visual layout or images — use browser_screenshot. Paid: $0.005 per call via x402 (Base USDC, Solana USDC, or XRPL XRP).

Input parameters:

- `session_id` (string, required): Session ID. Reuse the same ID to keep cookies, login state and page position across calls; a new ID starts a fresh browser.

Output parameters:

- `snapshot` (string)
- `url` (string)

### `browser_act` (~186 tokens)

Act on the current page

Use for: interacting with the page — click, fill, type, select, submit, press. Returns the resulting page title, URL and text so you can verify the action landed. Don't use when: the target element is not on the current page — navigate or snapshot first. This tool can change remote state (it can submit forms). Paid: $0.01 per call via x402 (Base USDC, Solana USDC, or XRPL XRP).

Input parameters:

- `action` (string, required): The interaction to perform on the target element.
- `selector` (string, required): CSS selector of the target element.
- `session_id` (string, required): Session ID. Reuse the same ID to keep cookies, login state and page position across calls; a new ID starts a fresh browser.
- `value` (string): Value for fill/type/select, or key name for press (default Enter).

Output parameters:

- `success` (boolean)
- `text` (string)
- `title` (string)
- `url` (string)

### `browser_screenshot` (~150 tokens)

Screenshot the current page

Use for: visual verification — layout, images, charts, CAPTCHA presence, or evidence of page state. Returns a PNG image (JPEG if the PNG exceeds 2.5MB). Don't use when: you only need the page's content or structure — browser_extract and browser_snapshot are far cheaper in tokens. Paid: $0.02 per call via x402 (Base USDC, Solana USDC, or XRPL XRP).

Input parameters:

- `full_page` (boolean): Capture the full scrollable page instead of the viewport.
- `session_id` (string, required): Session ID. Reuse the same ID to keep cookies, login state and page position across calls; a new ID starts a fresh browser.

Output parameters:

- `bytes` (number)
- `mime_type` (string)
- `url` (string)

### `browser_close` (~76 tokens)

Close a browser session

Use for: ending a session and freeing its browser. Sessions also expire automatically after 10 idle minutes. Free on every door — closing is never charged. Free.

Input parameters:

- `session_id` (string, required): Session ID. Reuse the same ID to keep cookies, login state and page position across calls; a new ID starts a fresh browser.

Output parameters:

- `closed` (boolean)
- `session_id` (string)
