# Price Watch — how to use (mcp.ai)

Compare product prices across stores, with value, seller, rating and image. Useful for price research before buying and to track how competitors are pricing the same item. Accepts up to 100 products in a single call. Hosted by the platform, no credentials, you pay per query.

## Option A — via MCP (recommended)
Remote MCP endpoint (HTTP, streamable): `https://api.mcp.ai/p_price_watch?ms=1788152160000`
Add it as a custom/remote MCP connector in your client (Claude, Cursor, VS Code…), then authenticate when prompted. Once connected, ask the agent to use the server's tools (e.g. `price_watch_search`).

## Option B — via direct REST API
Base URL: `https://api.mcp.ai/api/price_watch`
Auth: `Authorization: Bearer sk_live_…` — create a workspace API key at https://mcp.ai/settings/api-keys
