Available components
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
- Source repository is publicly reachable at the declared URL. View diagnostics → Pass
- Provenance check failed: no build-provenance attestation is published. See how to fix → View diagnostics → Fail
- Clear OSI-approved license (Apache-2.0).Pass
- Actively maintained (last published 110 days ago).Pass
- Disclosure check failed: no security disclosure policy was found in the source repository. See how to fix → Fail
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.

The dependency tree was only partially resolved, so these counts may be incomplete.
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.
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.
| Name | Type | Req | Description |
|---|---|---|---|
| button | string | — | — |
| clickCount | integer | — | — |
| ref | string | yes | A [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.
| Name | Type | Req | Description |
|---|---|---|---|
| expression | string | yes | JS expression (not a statement). Executes in the page's MAIN execution world — observable by page scripts. Use sparingly; prefer AOM + actions. |

| deltaOnly | boolean | — | Return markdown only if the readable content changed since the last call. |
| direction | string | — | — |

browser_set_proxy ~74

| server | string | — | e.g. http://host:port — omit to clear. |

| rotation | string | — | Rotation 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.
| Name | Type | Req | Description |
|---|---|---|---|
| mode | string | — | 'aom' = accessibility YAML only (cheap). 'vision' = raw screenshot. 'hybrid' = YAML + screenshot with red-boxed refs overlaid. |
No output schema declared.
