# ShopSavvy MCP Server

Give any AI assistant real-time product prices, price history, deals and buying guides from [ShopSavvy](https://shopsavvy.com), via the [Model Context Protocol](https://modelcontextprotocol.io/).

**No signup and no API key needed.** Anonymous use is rate-limited per IP (10 tool calls per minute, 100 per hour). Add a Data API key for higher limits.

## Two ways to connect

### 1. Remote server (recommended)

ShopSavvy hosts the server. Clients that support remote MCP servers connect by URL, with nothing to install:

```
https://api.shopsavvy.com/mcp
```

That's the Streamable HTTP endpoint. Older clients that only speak the HTTP+SSE transport can use `https://api.shopsavvy.com/mcp/sse`.

Per-client setup (Claude Code, Claude Desktop, claude.ai, ChatGPT, Codex, Gemini CLI, Cursor, VS Code, Windsurf) is at **[shopsavvy.com/agents](https://shopsavvy.com/agents#install)**.

### 2. This package (for stdio-only clients)

Some clients can only launch a local command. This package is that command: a small bridge that relays MCP messages between your client and the hosted server. The tools always match the hosted server, because they come from it.

Requires Node.js 18+.

**Claude Desktop** — add to `claude_desktop_config.json` (macOS: `~/Library/Application Support/Claude/`, Windows: `%APPDATA%\Claude\`):

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

Any other stdio client: run `npx -y @shopsavvy/mcp-server`.

## Higher limits with an API key

Get a key at [shopsavvy.com/data](https://shopsavvy.com/data), then:

- **Remote server:** send the header `Authorization: Bearer ss_live_…`
- **This package:** set the `SHOPSAVVY_API_KEY` environment variable:

```json
{
  "mcpServers": {
    "shopsavvy": {
      "command": "npx",
      "args": ["-y", "@shopsavvy/mcp-server"],
      "env": { "SHOPSAVVY_API_KEY": "ss_live_your_key_here" }
    }
  }
}
```

## Try asking

- "What's the best price for AirPods Pro right now?"
- "Show me the price history for B0D1XD1ZV3 over the last month."
- "Best air fryers, and where are they cheapest?"
- "Is now a good time to buy a TV?"

## Development

```bash
git clone https://github.com/shopsavvy/shopsavvy-mcp-server
cd shopsavvy-mcp-server
bun install
bun run build
bun test
```

`SHOPSAVVY_MCP_URL` points the bridge (and its tests) at another deployment of the server.
