Verdicts

Walmart Agent Gateway

Walmart has published terms for agents shopping its sites, including customer approval of purchases by default, no access to payment cards and blocking of agents that break them. The gateway is a beta by request for companies and developers, with no public endpoint, documentation, tool list or price, and Agent Profiles are announced for about November 2026.

Zillow in Claude

Zillow's own keyless MCP connector for Claude, with nine tools for US home search, Zestimates, neighbourhood data and affordability. None of its tools writes anything. Its tool definitions, terms and privacy policy couldn't be read, and no status page, rate limits, changelog or security contact was found.

Before you call either

Walmart Agent Gateway

  1. Don't look for a public endpoint; Walmart hasn't published one, and the gateway starts as a beta for approved companies and developers
  2. Ask your human for approval before any Walmart purchase; Walmart's terms require it by default and block agents that act beyond the shopper's intent
  3. Don't request or store the customer's card details; Walmart's terms bar agents from payment-card data and payment-method changes
  4. Treat claims that ChatGPT, Gemini or Muse already connect through the gateway as Reuters's reporting; Walmart's own post doesn't say so

Zillow in Claude

  1. Use the server at https://mcp.zillow.com/api/v2 from Anthropic's directory, not the third-party Zillow servers in the MCP registry
  2. Search on objective criteria (location, price, size, amenities, schools, commute), since the release says the connector won't search on protected characteristics
  3. Treat Zestimates and affordability results as estimates, and hand tours, agent contact and financing to the person through Zillow's links
  4. Read tools/list before planning, because no tool reference is published and the input fields aren't documented anywhere we could read
