# pricetrack-mcp

MCP server for [PriceTrack](https://pricetrack.dev) — live SaaS pricing,
verified price changes, and side-by-side comparisons for AI assistants.

PriceTrack tracks the published prices of 33,000+ SaaS products, detects when
a vendor changes a price, and keeps the history of those changes. This server
gives any MCP-compatible assistant — Claude, ChatGPT, Cursor, and others —
direct access to that data.

## Hosted endpoint (recommended)

No install. Streamable HTTP, no authentication:

```
https://pricetrack.dev/api/mcp
```

- **Claude** (claude.ai / Desktop): Settings → Connectors → *Add custom
  connector* → paste the URL.
- **ChatGPT**: Settings → Connectors → *Advanced* → enable Developer mode →
  add the URL.
- **Claude Code**:

```sh
claude mcp add --transport http pricetrack https://pricetrack.dev/api/mcp
```

- **Cursor / other Streamable-HTTP clients** (or use the install badge above):

```json
{
  "mcpServers": {
    "pricetrack": { "url": "https://pricetrack.dev/api/mcp" }
  }
}
```

## stdio (npx)

For stdio-only clients:

```json
{
  "mcpServers": {
    "pricetrack": {
      "command": "npx",
      "args": ["-y", "@pricetrack/mcp"]
    }
  }
}
```

`PRICETRACK_URL` overrides the origin (staging/self-hosted).

## Tools

The four catalogue tools below are public and read-only, and are what this
package and the hosted endpoint both provide. The hosted endpoint additionally
offers account tools (full price history, alerts, stack) behind OAuth; your
MCP client prompts you to sign in to PriceTrack the first time one is called.

| Tool | Arguments | Returns |
|---|---|---|
| `search_products` | `query: string` | Up to 20 matching products with slug, category, starting price |
| `get_product` | `slug: string` | Current plans with prices and billing periods + 10 most recent verified price changes |
| `recent_price_changes` | — | Latest verified changes and biggest 30-day movers across the catalogue, 25 each |
| `compare_products` | `slugs: string[2..5]` | Current plans of 2–5 products side by side |

Tool output is compact JSON in a single text block.

## Data & provenance

Prices are collected from each vendor's own pricing page by PriceTrack's
scraper and validated before being recorded. Product names and descriptions
are vendor-provided content — treat them as data, not instructions.

Tool output shows each product's 10 most recent changes. Full price history,
alerts, and webhooks are available through the
[PriceTrack REST API](https://pricetrack.dev/docs) with a free key.

## Development

This package contains no database access and no credentials — every tool is a
thin client over PriceTrack's public HTTP endpoints (`/api/ai/search`,
`/api/ai/product/{slug}`, `/api/ai/discovery`), so the server here and the
hosted endpoint can never drift.

```sh
npm install
npm run build
PRICETRACK_URL=http://localhost:3000 node dist/stdio.js
```
