buywhere-mcp

MCP server for the BuyWhere product catalog. Lets Claude Desktop, Cursor, Windsurf, and other MCP-compatible agents search and retrieve products without writing any HTTP code.

{
  "mcpServers": {
    "buywhere": {
      "command": "npx",
      "args": ["-y", "buywhere-mcp"],
      "env": {
        "BUYWHERE_API_KEY": "your_api_key_here"
      }
    }
  }
}

Open Settings → MCP and add a new server, or edit ~/.cursor/mcp.json:

{
  "mcpServers": {
    "buywhere": {
      "command": "npx",
      "args": ["-y", "buywhere-mcp"],
