## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data or untrusted-input or outbound.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | none |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | none |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

No check matched anything in these tool definitions.


## Changes things (2)

Creates or changes something that can be changed back. Claude Code: ask.

### `create_price_alert`

- The name "create_price_alert" says "create": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Create an email alert on a product's price for the signed-in user. Fires when the product's price changes (any_change) or moves by at least a threshold percentage. This modifies the user's account — only call when they explicitly ask to be alerted or to watch a product's price.
```

### `recent_price_changes`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
The most recent verified SaaS price changes and the biggest movers of the last 30 days, across the whole catalogue. Call this when the user asks what changed in SaaS pricing lately, who raised prices recently, or for examples of price increases. Fixed snapshot of up to 25 entries per group — no pagination.
```

## Only reads (6)

Looks things up and changes nothing. Claude Code: allow.

### `compare_products`

- The name "compare_products" says "compare": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Compare the current pricing plans of 2 to 5 SaaS products side by side. Call this when the user is choosing between named products and wants their prices in one view. Takes product slugs (find them with search_products).
```

### `get_price_history`

- The name "get_price_history" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
The complete verified price-change history of a product, beyond the public 10-change window. Requires the user's PriceTrack account. Call when the user asks how a product's price evolved over time, or for changes older than the recent ones get_product shows.
```

### `get_product`

- The name "get_product" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Get a SaaS product's current pricing plans and its most recent price changes. Call this when the user asks what a specific product costs, what plans it offers, or whether its price changed recently. Takes the product slug (find it with search_products). Shows the 10 most recent changes; deeper history requires a free PriceTrack API key.
```

### `get_stack`

- The name "get_stack" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
The products the signed-in user tracks on PriceTrack, with each one's current lowest paid price and an estimated monthly total.
```

### `list_alerts`

- The name "list_alerts" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
The user's active price alerts on PriceTrack. Requires their account.
```

### `search_products`

- The name "search_products" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Search PriceTrack's catalogue of tracked SaaS products by name or description. Call this when the user asks what a SaaS product costs and you need its slug, or when they describe a kind of tool and want priced options. Returns up to 20 matches with slug, category, and starting price. Use get_product with a returned slug for full plan details.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `pricetrack`:

```json

  "permissions": {
    "allow": [
      "mcp__pricetrack__search_products",
      "mcp__pricetrack__get_product",
      "mcp__pricetrack__compare_products",

    ],
    "deny": []

- **warn** Tools that change things, listed to anyone ([unauth-remote-writes](https://anlyon.dev/methodology#unauth-remote-writes))

```untrusted-server-text
The endpoint served tools/list without credentials, and the list has 2 tools that change things (2 write). Whether a call also works without credentials was not tested: tools are never called.

https://pricetrack.dev/api/mcp: tools/list returned 8 tools to an anonymous client, including recent_price_changes (write), create_price_alert (write)
