pricetrack-mcp
MCP server for PriceTrack — 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:
claude mcp add --transport http pricetrack https://pricetrack.dev/api/mcp
- Cursor / other Streamable-HTTP clients (or use the install badge above):
{
"mcpServers": {
"pricetrack": { "url": "https://pricetrack.dev/api/mcp" }
}
}
stdio (npx)
For stdio-only clients:
{
"mcpServers": {
"pricetrack": {
"command": "npx",
"args": ["-y", "@pricetrack/mcp"]
}
}
}
PRICETRACK_URL overrides the origin (staging/self-hosted).
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 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.
