## Trust breakdown

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. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-08-03.

- **Supply Chain Security**: 81/100
  - No malware found by supply-chain analysis.
  - Only part of the dependency tree could be resolved (98 of 102), so this covers what we could see, not the whole tree.
  - Runs a script at install time (postinstall) that we could not recognise. It may be perfectly ordinary, but we do not read the published tarball, so we cannot say what it does.
  - Only part of the dependency tree could be resolved (98 of 102), so this covers what we could see, not the whole tree.
- **Provenance & Transparency**: 45/100
  - Source repository is publicly reachable at the declared URL.
  - Provenance check failed: no build-provenance attestation is published.
  - Clear OSI-approved license (MIT).
  - Actively maintained (last published 22 days ago).
  - Disclosure check failed: no security disclosure policy was found in the source repository.
- **Schema Quality & AI Usability**: 77/100
  - AI-judged instruction clarity (excellent).
  - Tool/resource definitions use about 790 tokens (~79/item across 10 items; 10 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 27/100
  - Stability observed for 8 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 82/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 46% of tool parameters carry a description.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## Changelog

Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

### 2026-08-03 (score 66, +1)

No change was recorded against any check on this day. Stability & Change Management went from 23 to 27. That category is still filling its 30-day observation window: 7 days of observed history at the previous scan, 8 at this one. The score rises as the window fills, whether or not the server changes.

## MCP tools (10)

### `aethyn_launch_browser` (~227 tokens)

Launch proxied browser

Launch a local Chromium routed through a residential proxy exit in a chosen country (and city/state on the Elite tier). Returns a session_id the other aethyn_* tools use. Each session is one sticky identity — a pinned exit IP for the whole task.

Input parameters:

- `city` (string): City for Elite-tier targeting, e.g. 'tokyo'. Requires tier:'elite'.
- `country` (string, required): ISO-3166-1 alpha-2 country code, e.g. 'jp', 'de', 'us'.
- `headless` (boolean): Run headless. Default true.
- `lifetime_min` (integer): Sticky lifetime in minutes (1–1440, default 10).
- `session` (string): Your task id. Reuse the same value to pin the same exit IP. Letters/digits/underscore only. Omit to auto-generate.
- `state` (string): State/region for Elite-tier targeting. Requires tier:'elite'.
- `tier` (string): Proxy tier. Elite unlocks city/state targeting. Default 'premium'.

### `aethyn_navigate` (~82 tokens)

Navigate

Navigate the session's browser to a URL and wait for load. Returns the HTTP status, final URL, and page title — read the page with aethyn_get_content to judge the response yourself. Public data only — respect robots.txt, rate limits, and each site's terms.

Input parameters:

- `session_id` (string, required)
- `url` (string, required)

### `aethyn_get_content` (~47 tokens)

Get page content

Return the current page's content cleaned for reading (markdown by default). Use after navigating to extract data.

Input parameters:

- `format` (string)
- `session_id` (string, required)

### `aethyn_snapshot` (~58 tokens)

Accessibility snapshot

Return a structured accessibility snapshot (roles, names, and [ref=..] handles) of the page. Pass those refs to aethyn_click / aethyn_type. No screenshots needed.

Input parameters:

- `session_id` (string, required)

### `aethyn_click` (~99 tokens)

Click

Click an element. Prefer a 'ref' from aethyn_snapshot (e.g. 'e12'); or pass a 'selector' (CSS, or Playwright role=/text= engine).

Input parameters:

- `ref` (string): Element ref from aethyn_snapshot, e.g. 'e12'.
- `selector` (string): Fallback selector (CSS, role=..., or text=...).
- `session_id` (string, required)

### `aethyn_type` (~80 tokens)

Type text

Type text into an input. Prefer a 'ref' from aethyn_snapshot; or a 'selector'. Set submit:true to press Enter after.

Input parameters:

- `ref` (string)
- `selector` (string)
- `session_id` (string, required)
- `submit` (boolean): Press Enter after typing.
- `text` (string, required)

### `aethyn_check_exit_ip` (~65 tokens)

Verify exit IP / geo

Fetch IP info THROUGH the session's proxy so you can verify the exit country/city actually landed before trusting the page. Returns ip, country, city, org/ASN, and a best-effort is_residential flag.

Input parameters:

- `session_id` (string, required)

### `aethyn_new_identity` (~48 tokens)

Rotate identity

Rotate the session to a fresh residential exit (new IP, same country) and clear cookies. Use between independent tasks or after a soft-block.

Input parameters:

- `session_id` (string, required)

### `aethyn_close` (~36 tokens)

Close session

Close the session's browser context and free memory. Call this when a task is done.

Input parameters:

- `session_id` (string, required)

### `aethyn_list_countries` (~48 tokens)

List countries / cities

List available exit countries (and Elite-tier cities where known). Discover geo options at runtime before launching.

Input parameters:

- `with_cities` (boolean): Only return countries that have known cities.
