HasData Walmart MCP server

Walmart MCP Server

<!-- mcp-name: com.hasdata/walmart -->

A hosted Model Context Protocol (MCP) server that gives Claude, Cursor, Windsurf and any other MCP client three read-only Walmart tools. Run a keyword or category search, read one item with the seller holding the buy box, and page through its customer reviews, all as structured JSON, with no Walmart developer account and nothing to host.

It reads public Walmart pages that a signed-out visitor can see, on walmart.com and walmart.ca.

1,000 free credits every month, no card required, which is 100 Walmart calls at the 10-credit rate.

What you need

An MCP client and a HasData API key from the dashboard, free to create with no card, and the free tier covers about 100 calls a month at the 10-credit rate. This is a remote server, so the simplest path is a URL and an x-api-key header, with no container to run. A client that only speaks stdio reaches it through a thin launcher, published as @hasdata/walmart-mcp on npm and hasdata-walmart-mcp on PyPI, shown below.

Quick start

The server URL is the same for every client. We run it hands-on in Claude Code and Claude Desktop. The other blocks follow each client's own documented format for a remote server.

Clients with OAuth support can add the same URL as a connector and sign in without putting a key in a config file.

Claude Code

claude mcp add --transport http walmart "https://mcp.hasdata.com/api/mcp?apis=walmart" \
  --header "x-api-key: HASDATA_API_KEY"

Claude Desktop

Settings, then Connectors, then Add custom connector, then paste https://mcp.hasdata.com/api/mcp?apis=walmart and sign in.

For the config-file route, Claude Desktop loads only local (stdio) servers, so it reaches a remote server through a stdio launcher. The @hasdata/walmart-mcp package is that launcher, and it reads the key from the environment. Add this to claudedesktopconfig.json:

{
  "mcpServers": {
    "walmart": {
      "command": "npx",
      "args": ["-y", "@hasdata/walmart-mcp"],
      "env": { "HASDATA_API_KEY": "YOUR_KEY" }
    }
  }
}
