68 Trust /100
Trust breakdown (7 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 → Why this is hard to score →

Supply Chain Security98
  • No malware found by supply-chain analysis.Pass
  • No known CVEs affecting this package version or its production dependencies.Pass
  • No install/post-install scripts declared.Pass
  • 32 of 98 dependencies flagged as unhealthy. View diagnostics → Partial
Provenance & Transparency45
Schema Quality & AI Usability81
  • AI-judged instruction clarity (excellent).Pass
  • Tool/resource definitions use about 4820 tokens (~73/item across 66 items; 66 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
  • 59% of tool parameters carry a description.Partial
Tool Safety75
  • No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
  • 0 of 7 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "browser_run_code_unsafe" implies "execute" and declares no destructiveHint at all, which the MCP spec reads as destructive by default. See how to fix → Fail
  • An AI judge read all 66 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

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 · 66 exposed · ~4,820 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. 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 →

Tool Tokens
browser_add_init_script ~179

Register JavaScript that runs before any page script, on every navigation (Playwright's page.addInitScript — always in the page's main world). Unlike browser_evaluate, this is proactive: it wins the race against a site's own inline <script> (e.g. Cloudflare/Turnstile checks that run synchronously on document parse), which a reactive evaluate call issued over the MCP connection cannot. Call this BEFORE browser_navigate to the target URL — it has no effect on a page already loaded, only on the page it's called on and future navigations of that same page. Scoped to the current page only.

NameTypeReqDescription
functionstringFunction body/expression to install as the init script, e.g. '() => { window.foo = 1; }'.
scriptstringDeprecated alias for function.

No output schema declared.

No examples provided.

browser_api_request ~110

Make an HTTP request reusing the browser session's cookies/storage (authenticated API calls without re-login). Returns status, headers, and body.

NameTypeReqDescription
dataRequest body: a string, or an object (sent as JSON).
headersobjectRequest headers as key/value strings.
maxBytesnumberTruncate response body to this many chars. Default 100000.

timeoutnumber

No output schema declared.

No examples provided.

browser_evaluate ~254

Evaluate JavaScript in the active page. Pass 'function' for a function body, 'expression' for a plain expression, or 'script' (deprecated). By default JS runs in an isolated stealth world (DOM is shared, but the page's own window globals are NOT visible). Set world:'main' to run in the page's real world — required to read or call globals the page defined (e.g. a page-registered callback). Pass frameSelector to run inside a specific iframe (including cross-origin ones, e.g. a captcha widget hosted on a different domain) instead of the top-level page — same CSS selector browser_click/browser_fill/browser_type already accept.

expressionstring

browser_run_code_unsafe ~107

No output schema declared.

No examples provided.

browser_save_blob ~326

Evaluate JavaScript in the page and write the result straight to a file on disk — the value itself never passes through this tool's response. Use this instead of browser_evaluate whenever you need to get a large/opaque blob (base64 image(s), a full page's HTML, a big JSON dump) out of the live page and into a request body: reading it via browser_evaluate and then re-typing/pasting it into another tool call's arguments (e.g. create_task's imagesBase64/htmlPageBase64) risks silently corrupting it — a dropped character or an unclosed quote partway through a multi-KB string merges what should be several array elements into one, with no clear error. Pass 'function' or 'expression' (same as browser_evaluate); pass encoding:'base64' when the value is a base64 string (a data:...;base64, prefix is stripped automatically) to write raw decoded bytes, or omit it to write the value as UTF-8 text (non-strings are JSON-stringified).

NameTypeReqDescription
encodingstring'base64' decodes the evaluated string into raw bytes before writing. 'text' (default) writes UTF-8 (JSON-stringifying non-string results).
expressionstring
functionstring
pathstringyesOutput file path.
worldstringExecution world. 'isolated' (default) = stealth, page globals hidden; 'main' = page's real world, page globals visible/callable.

No output schema declared.

NameTypeReqDescription
formatstring
landscapeboolean
pathstringOutput file path. If omitted, returns base64.
printBackgroundbooleanInclude background graphics. Default true.
scalenumberRender scale, default 1.

No output schema declared.

No examples provided.
