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 Security93
- No malware found by supply-chain analysis.Pass
- No known CVEs affecting this package version or its production dependencies.Pass
- Declares code that runs automatically (build-time code we could not rule out (a Hatch, PDM or setuptools build hook, a dynamic version we could not read statically, shipped VCS metadata or a stray root module)) and that we could not recognise. It may be perfectly ordinary, but we have not established what it does. View diagnostics → Partial
- 1 of 35 dependencies flagged as unhealthy. View diagnostics → Partial
Provenance & Transparency97
- Source repository is publicly reachable at the declared URL. View diagnostics → Pass
- Cryptographically verified build provenance (signed, bound to LinVireo/browsertap-mcp). View diagnostics → Pass
- Clear OSI-approved license (MIT).Pass
- Actively maintained (last published 50 days ago).Pass
- Security-disclosure policy not yet verified: we couldn't inspect the source repository.Unverified
Schema Quality & AI Usability80
- AI-judged instruction clarity (excellent).Pass
- Tool/resource definitions use about 5474 tokens (~99/item across 55 items; 55 tools + 0 resources), lean.Pass
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management100
- No destabilizing schema changes in the last 30 days.Pass
Tool Coverage71
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 0% of tool parameters carry a description.Fail
- Structured output schemas are declared (96% of tools); any adoption earns full credit.Pass
Tool Safety75
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- 0 of 6 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "uninstall_extension" implies "uninstall" 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 56 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

No change was recorded against any check on this day. Stability & Change Management went from 80 to 83. That category is still filling its 30-day observation window: 24 days of observed history at the previous scan, 25 at this one. The score rises as the window fills, whether or not the server changes.

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 →
type_text ~174
Type text via the real keyboard, optionally after clicking a field at click_x/click_y in absolute virtual-desktop PHYSICAL screen pixels (see mouse_click for how that differs from the CSS pixels the page_* tools take); a click point on no display is refused with coordinates_off_screen. Pass session_id — the same one you pass every other tool (preferred) — and that tab is raised after the quiet check so the keystrokes go to it. Without one the current global target is raised, which another task may have changed. Approval may foreground the selected browser tab. activate_session='none' types into whatever already has focus.
| Name | Type | Req | Description |
|---|---|---|---|
| activate_session | – | – | – |
| click_x | – | – | – |
| click_y | – | – | – |
| interval | number | – | – |
| session_id | – | – | – |
| text | string | yes | – |
Structured output declared, but exposes no named fields.
No examples provided.
uninstall_extension ~70
Uninstall another installed extension by id. show_confirm_dialog defaults to true; set it false only for an explicitly selected disposable/test extension. The BTAP bridge cannot uninstall itself through its active connection.
| Name | Type | Req | Description |
|---|---|---|---|
| extension_id | string | yes | – |
| session_id | – | – | – |
| show_confirm_dialog | boolean | – | – |
Structured output declared, but exposes no named fields.
No examples provided.
upload_files ~85
Set files on a file input, which JS cannot do (input.files is read-only). Give a CSS selector for the <input type=file> and absolute local paths. Runs as a single CDP batch so the DOM node ids stay valid across the sequence.
| Name | Type | Req | Description |
|---|---|---|---|
| paths | – | yes | – |
| selector | string | yes | – |
| session_id | – | – | – |
| timeout | number | – | – |
Structured output declared, but exposes no named fields.
No examples provided.
wait_for ~149
Wait until a condition holds on the page, then return. Use this instead of polling scan_page (each scan re-serializes the whole DOM). Exactly one of selector / text / url_pattern / js must be given: selector waits for a CSS match, text for a substring in body text, url_pattern for a regex on the URL, js for a JS expression to become truthy. Polls inside the page, so it costs one bridge roundtrip regardless of how long the wait takes.
| Name | Type | Req | Description |
|---|---|---|---|
| gone | boolean | – | – |
| js | – | – | – |
| selector | – | – | – |
| session_id | – | – | – |
| text | – | – | – |
| timeout | number | – | – |
| url_pattern | – | – | – |
Structured output declared, but exposes no named fields.
No examples provided.
wait_for_url ~131
Wait for navigation to settle: blocks until the tab's URL matches url_pattern (regex, or plain substring) and — unless wait_ready=false — document.readyState is 'complete', then returns the final url, title and readyState. Use this after a click or open_url that navigates; wait_for(url_pattern=...) only checks the URL and can return while the new document is still blank. Polls in-page, so a long wait is still cheap.
| Name | Type | Req | Description |
|---|---|---|---|
| session_id | – | – | – |
| timeout | number | – | – |
| url_pattern | string | yes | – |
| wait_ready | boolean | – | – |
Structured output declared, but exposes no named fields.
