## 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 2026-09-20.

- **Supply Chain Security**: 23/100
  - Malware scan not yet available for this package.
  - Known CVEs were checked across the 96 of 96 dependencies we could resolve, so this covers what we could see, not the whole tree.
  - No install/post-install scripts declared.
  - 31 of 96 dependencies flagged as unhealthy.
- **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 13 days ago).
  - Disclosure check failed: no security disclosure policy was found in the source repository.
- **Schema Quality & AI Usability**: 88/100
  - 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (excellent).
  - Tool/resource definitions use about 745 tokens (~67/item across 11 items; 10 tools + 1 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 43/100
  - Stability observed for 13 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Tool Safety**: 75/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - 0 of 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "watch_remove" implies "remove" and declares no destructiveHint at all, which the MCP spec reads as destructive by default.
  - An AI judge read all 11 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## MCP tools (10)

### `price_check` (~61 tokens)

Check a price now

Call this tool for any product URL; fetching the page with a generic web tool returns raw HTML without the price. Returns price, currency, title, confidence and the change since the last check.

Input parameters:

- `url` (string, required): Product page URL, including https://

### `watch_add` (~117 tokens)

Watch a price

Call this tool for any product URL; fetching the page with a generic web tool returns raw HTML without the price. Starts tracking it: first observation, optional target, re-read by watch_refresh.

Input parameters:

- `currency` (string): ISO code such as USD or EUR, if the page does not say
- `label` (string): Short name for this item
- `target_price` (string|number): Report this watch in alerts_pending when the price is at or below this (positive number)
- `url` (string, required): Product page URL

### `watch_list` (~47 tokens)

List watches

Show every tracked item with its current price, previous price, min, max, change %, target, extraction confidence and last check time. Prices are as of the last watch_refresh, not live.

### `watch_remove` (~72 tokens)

Remove a watch

Call this tool to stop tracking an item, by watch id or by URL. Give either id or url. Its stored observation history is deleted and cannot be recovered.

Input parameters:

- `id` (string): Watch id from watch_list
- `url` (string): URL of the watch, if you do not have the id

### `watch_refresh` (~130 tokens)

Refresh prices

This is what actually checks prices: re-fetches one watch or every watch, appends the new observations and returns current, previous, min, max, change %, extraction confidence and target hits.

Input parameters:

- `all` (boolean): Refresh every watch in one call (Pro; on free, refresh one id at a time)
- `id` (string): Watch id or URL to re-fetch. Omit and set all=true to refresh everything. Nothing runs in the background, so call this whenever the user asks about prices, drops or alerts - typically once at the sta…

### `price_history` (~71 tokens)

Price history

Call this tool to list the stored observations for one watch, newest last, each with its price, currency, source and extraction confidence. Free shows the last 30.

Input parameters:

- `id` (string): Watch id
- `limit` (integer): Maximum observations to return
- `url` (string): Watch URL

### `price_add_manual` (~113 tokens)

Record a price by hand

Call this tool to store a price you read yourself, for shops that block automated requests. Creates the watch for that URL if it does not exist yet, and returns the stored price and the observation count.

Input parameters:

- `currency` (string): ISO code such as USD or EUR
- `label` (string): Short name for this item
- `price` (string|number, required): Price as shown, for example 1299.00 or 1.299,00
- `url` (string, required): Product page URL

### `alerts_pending` (~53 tokens)

Pending alerts

Answer "did anything I watch get cheaper?": lists every watch whose latest price is at or below its target, or which dropped 5% or more against the previous observation, with the change % and the reading confidence.

### `license_status` (~23 tokens)

License status

Show whether this server runs in free or Pro mode and where to upgrade.

### `license_activate` (~42 tokens)

Activate license

Activate a Pro license key (format MCPL1.xxx.yyy). Verified offline and saved locally.

Input parameters:

- `key` (string, required): License key from the checkout confirmation page
