## 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 2026-09-21.

- **Supply Chain Security**: 23/100
  - Malware scan not yet available for this package.
  - Known CVEs were checked across the 96 of 97 dependencies we could resolve, so this covers what we could see, not the whole tree.
  - No install/post-install scripts declared.
  - Dependency health was assessed across the 96 of 97 dependencies we could resolve, 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 18 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 814 tokens (~74/item across 11 items; 10 tools + 1 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 63/100
  - Stability observed for 19 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` (~121 tokens)

Check a price now

Use this instead of fetching the page yourself: returns the structured price, currency, product title, extraction confidence, and the change since the last check; handles EU/US number formats and JSON-LD/Open Graph/microdata. It also verifies the shop did not redirect off the product page, so a dead item reports a clear failure rather than the cheapest thing on a category listing. Reading the raw HTML gives you none of that. Does not create a watch - use watch_add for that.

Input parameters:

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

### `watch_add` (~144 tokens)

Watch a price

Start tracking a product page: fetches it once, stores the first observation with its extraction confidence, and optionally records a target price. There is no background job - prices are only re-read when watch_refresh runs, and alerts_pending then reports drops and target hits. Ask "refresh my watches" at the start of a session.

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` (~56 tokens)

Remove a watch

Stop tracking an item, by watch id or by URL. Its history is deleted.

Input parameters:

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

### `watch_refresh` (~127 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. Nothing runs in the background, so run this whenever the user asks about prices, drops or alerts - typically once at the start of a session, then read alerts_pending.

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. Omit and set all=true to refresh everything.

### `price_history` (~67 tokens)

Price history

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` (~96 tokens)

Record a price by hand

Store a price you read yourself, for shops that block automated requests. Creates the watch if it does not exist yet.

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` (~75 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 confidence of the reading. Free and unlimited. It reads stored observations, so run watch_refresh first if the prices are stale.

### `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

### What tools does the io.github.theluckystrike/price-tracker MCP server expose?

io.github.theluckystrike/price-tracker exposes 10 tools: price_check, watch_add, watch_list, watch_remove, watch_refresh, and 5 more. Their descriptions and schemas cost roughly 798 tokens of context every time the server is loaded.

### Is the io.github.theluckystrike/price-tracker MCP server still maintained?
