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. How we score → Why this is hard to score →
Endpoint Security57
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation check failed: no authorisation is required to call this server, and it exposes a tool marked destructive (browser_act). See how to fix → View diagnostics → Fail
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability77
- AI-judged instruction clarity (excellent).Pass
- 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. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management30
- Stability observed for 9 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 6 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 6 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
browser_act Act on the current page ~186
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).
| Name | Type | Req | Description |
|---|---|---|---|
| action | string | yes | The interaction to perform on the target element. |
| selector | string | yes | CSS selector of the target element. |
| session_id | string | yes | 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). |
| Name | Type | Req | Description |
|---|---|---|---|
| success | boolean | yes | – |
| text | string | yes | – |
| title | string | yes | – |
| url | string | yes | – |
No examples provided.
browser_close Close a browser session ~76
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.
| Name | Type | Req | Description |
|---|---|---|---|
| session_id | string | yes | Session ID. Reuse the same ID to keep cookies, login state and page position across calls; a new ID starts a fresh browser. |
| Name | Type | Req | Description |
|---|---|---|---|
| closed | boolean | yes | – |
| session_id | string | yes | – |
No examples provided.
browser_extract Extract data from the current page ~169
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).
| Name | Type | Req | Description |
|---|---|---|---|
| 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 | yes | Session ID. Reuse the same ID to keep cookies, login state and page position across calls; a new ID starts a fresh browser. |
| Name | Type | Req | Description |
|---|---|---|---|
| count | number | yes | – |
| results | array | yes | – |
No examples provided.
browser_navigate Navigate to a URL ~175
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).
| Name | Type | Req | Description |
|---|---|---|---|
| session_id | string | yes | 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 | yes | Absolute http(s) URL to load. |
| wait_for | string | – | Optional CSS selector to wait for after load (max 10s). |
| Name | Type | Req | Description |
|---|---|---|---|
| session_id | string | yes | – |
| text | string | yes | – |
| title | string | yes | – |
| url | string | yes | – |
No examples provided.
browser_screenshot Screenshot the current page ~150
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).
| Name | Type | Req | Description |
|---|---|---|---|
| full_page | boolean | – | Capture the full scrollable page instead of the viewport. |
| session_id | string | yes | Session ID. Reuse the same ID to keep cookies, login state and page position across calls; a new ID starts a fresh browser. |
| Name | Type | Req | Description |
|---|---|---|---|
| bytes | number | yes | – |
| mime_type | string | yes | – |
| url | string | yes | – |
No examples provided.
browser_snapshot Accessibility snapshot of the current page ~132
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).
| Name | Type | Req | Description |
|---|---|---|---|
| session_id | string | yes | Session ID. Reuse the same ID to keep cookies, login state and page position across calls; a new ID starts a fresh browser. |
| Name | Type | Req | Description |
|---|---|---|---|
| snapshot | string | yes | – |
| url | string | yes | – |
