Trust breakdown (6 categories)

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. How we score →

Supply Chain Security71
  • No malware found by supply-chain analysis.Pass
  • CVE check failed: a known high-severity CVE affects sharp 0.33.5, a direct dependency. A fixed version is available. View diagnostics → Fail
  • No install/post-install scripts declared.Pass
  • Only part of the dependency tree could be resolved (192 of 194), so this covers what we could see, not the whole tree. View diagnostics → Partial
Provenance & Transparency45
Schema Quality & AI Usability70
  • AI-judged instruction clarity (good).Pass
  • Tool/resource definitions use about 959 tokens (~73/item across 13 items; 13 tools + 0 resources), lean.Pass
  • Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management0
  • Stability not yet verified: not enough scan history yet (needs a 30-day window).Unverified
Tool Coverage86
  • 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
  • 58% of tool parameters carry a description.Partial
Capabilities100
  • Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

Unverified: 1 category

A category scored 0 because we could not verify it: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm.

MCP tools — 13 exposed · ~959 tokens

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.

Tool Tokens
browser_click ~92

Click an element addressed by its ref. When SAB_HUMAN_MOUSE=true (default), the cursor travels via a Bezier path with pre-click hesitation — this defeats trajectory analyzers like Datadome that flag teleporting mice.

NameTypeReqDescription
buttonstring
clickCountinteger
refstringyesA [ref=eN] id taken from the last aom/hybrid snapshot.

No output schema declared.

No examples provided.

browser_eval ~75

Evaluate a JS EXPRESSION in the page's MAIN execution world. Observable by page scripts; use sparingly. Prefer AOM + action tools.

NameTypeReqDescription
expressionstringyesJS expression (not a statement). Executes in the page's MAIN execution world — observable by page scripts. Use sparingly; prefer AOM + actions.

No output schema declared.

No examples provided.

browser_navigate ~90

Navigate the active session's page to a URL. Returns a snapshot (default: aom-only, cheapest).

NameTypeReqDescription
modestringSnapshot mode to return after navigation. 'aom' is cheapest; 'hybrid' adds a Set-of-Mark annotated screenshot.
urlstringyesFully-qualified URL to navigate to.
waitUntilstringPage lifecycle event to wait for.

No output schema declared.

No examples provided.

browser_restart ~39

Close the active browser session and start a fresh one with the current config. Required after 'browser_set_proxy' to actually route new requests through the proxy.

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

browser_scroll_read ~75

Scroll and return a Readability-extracted Markdown view. With deltaOnly=true, returns '(no change)' if nothing new became visible — keeps context windows lean.

NameTypeReqDescription
deltaOnlybooleanReturn markdown only if the readable content changed since the last call.
directionstring
pixelsinteger

No output schema declared.

No examples provided.

browser_select ~36

Select one or more options in a <select> addressed by ref.

NameTypeReqDescription
refstringyes
valuesarrayyes

No output schema declared.

No examples provided.

browser_set_proxy ~74

Update the proxy config. Call 'browser_restart' after this for the change to take effect (browser-level constraint — an existing context cannot be re-routed).

NameTypeReqDescription
passwordstring
serverstringe.g. http://host:port — omit to clear.
usernamestring

No output schema declared.

No examples provided.

browser_set_proxy_pool ~86

Replace the residential proxy pool at runtime. Takes effect on the next 'browser_restart'. Supports sticky sessions via SAB_PROXY_STICKY_TEMPLATE.

NameTypeReqDescription
poolstringResidential proxy pool: comma-separated URLs (http://u:p@host:port) or a JSON array. Omit to clear.
rotationstringRotation strategy. Default: per-restart.

No output schema declared.

No examples provided.

browser_snapshot ~87

Take a snapshot of the current page. 'aom' returns the accessibility YAML (token-lean); 'hybrid' adds a Set-of-Mark screenshot with numeric red boxes matching each ref.

NameTypeReqDescription
modestring'aom' = accessibility YAML only (cheap). 'vision' = raw screenshot. 'hybrid' = YAML + screenshot with red-boxed refs overlaid.

No output schema declared.

No examples provided.

browser_solve_captcha ~136

Fallback captcha solver. Detects Turnstile/hCaptcha/reCAPTCHA on the current page (or takes an explicit sitekey), submits to the configured provider (CapSolver or 2Captcha per SAB_CAPTCHA_PROVIDER + SAB_CAPTCHA_API_KEY), polls for a token, and injects it into the widget's response field.

NameTypeReqDescription
pageUrlstringPage URL the captcha is bound to. Defaults to the current page.
sitekeystringProvide explicitly when auto-detection fails.
typestringOverride auto-detection. Otherwise the active page is scanned for a known widget.
