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 → Why this is hard to score →
Supply Chain Security100
- No malware found by supply-chain analysis.Pass
- No known CVEs affecting this package version or its production dependencies.Pass
- Runs hatchling.build at install time, a recognised native-build step with no shell scripting around it. View diagnostics → Pass
- No production dependencies, so there is no dependency health to assess. View diagnostics → Pass
Provenance & Transparency35
- 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
- License check failed: no license is declared. See how to fix → Fail
- Actively maintained (last published 15 days ago).Pass
- Publishes a security disclosure policy (SECURITY.md).Pass
Schema Quality & AI Usability85
- AI-judged instruction clarity (excellent).Pass
- Tool/resource definitions use about 654 tokens (~72/item across 9 items; 9 tools + 0 resources), lean.Pass
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management53
- Stability observed for 16 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
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 9 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 10 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities60
- Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28. See how to fix → Fail

Provenance No attestation
The registry publishes no build provenance for this version, so there is nothing to verify.

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_click ~61
Click a CSS selector, or an x/y point in the viewport. Provide one, not both.
| Name | Type | Req | Description |
|---|---|---|---|
| selector | string | – | CSS selector to click. |
| x | integer | – | Viewport x coordinate. |
| y | integer | – | Viewport y coordinate. |
No output schema declared.
No examples provided.
browser_close ~35
End the session and release the browser. Idempotent. Call this when the task is finished so the single session slot is free.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
browser_navigate ~55
Navigate the session to an http(s) URL and return the page title, final URL and readable text. The server validates the destination and refuses blocked address classes.
| Name | Type | Req | Description |
|---|---|---|---|
| url | string | yes | Absolute http(s) URL to open. |
No output schema declared.
No examples provided.
browser_open ~60
Start the one headed Chrome session and return the live view URL. Give that URL to the human: they can watch this exact session, and take over in it, while you drive. Safe to call twice -- it reuses the session that is already open.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
browser_press ~89
Press one allowlisted key or combination. Allowed: Enter, Escape, Tab, Backspace, Delete, Space, ArrowUp, ArrowDown, ArrowLeft, ArrowRight, Home, End, PageUp, PageDown, Control+A, Control+Z, Control+Shift+Z, Meta+A, Meta+Z, Meta+Shift+Z.
| Name | Type | Req | Description |
|---|---|---|---|
| key | string | yes | Key to press. |
No output schema declared.
No examples provided.
browser_read ~81
Read the current page: title, URL, readable text and a bounded accessibility tree. Prefer this over a screenshot -- it is structure, not pixels, and it does not spend a vision step unless you ask for the image.
| Name | Type | Req | Description |
|---|---|---|---|
| include_screenshot | boolean | – | Also return the PNG as base64. Costs one vision step from the session budget. Default false. |
No output schema declared.
No examples provided.
browser_scroll ~48
Scroll the page by a nonzero pixel delta.
| Name | Type | Req | Description |
|---|---|---|---|
| delta_x | integer | – | Horizontal pixels. Positive scrolls right. |
| delta_y | integer | – | Vertical pixels. Positive scrolls down. |
No output schema declared.
No examples provided.
browser_status ~38
Report whether the runtime is up, whether a session is open, how many vision steps remain, and the live view URL to hand to a human.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
browser_type ~96
Type text into a CSS selector, or at an x/y point. Text is sent byte for byte. Do not use this for a secret a human should enter -- ask them to take over in the live view instead.
| Name | Type | Req | Description |
|---|---|---|---|
| selector | string | – | CSS selector to type into. |
| text | string | yes | Text to type. |
| x | integer | – | Viewport x coordinate. |
| y | integer | – | Viewport y coordinate. |
No output schema declared.
No examples provided.
