Walmart Marketplace MCP server for AI agents.

actionlake is an MCP gateway: one remote MCP server that connects Claude and other MCP clients to Walmart Marketplace and the rest of your systems. It gives your agent 190 Walmart Marketplace actions (118 reads, 56 writes and 16 that wait for a confirmation) and holds the Walmart Marketplace credential itself, so the agent never does. It paces Walmart Marketplace's limits and records every call.

100,000 free calls a month. No card, no email, no password: press Start a free sandbox on the next screen and keep the key it shows you.

Questions

The Walmart Marketplace MCP server, answered.

Is there a Walmart Marketplace MCP server for Claude?

Yes. actionlake is an MCP gateway: a remote MCP server that gives Claude, or another MCP client, 190 Walmart Marketplace actions across performance, items, ad campaigns and orders, through the same eight tools it uses for every other connector. actionlake is independent; it is not made or endorsed by Walmart Marketplace.

What do I need to connect Walmart Marketplace?

Walmart Marketplace Client ID and Walmart Marketplace Client Secret, shown beside the Client ID. Plus your host. The free call account { op: "connections.requirements", service: "walmart_marketplace" } lists exactly what to paste.

Can an AI agent delete or change things in Walmart Marketplace?

Only if its key allows it, and only with an explicit confirmation. 16 Walmart Marketplace actions are destructive, including retire an item, cancel Order Lines and cancel Inbound Shipment. Each runs only with confirm: true. Under the human confirm policy, or an approval rule on the key, the run waits until a named person approves it.

Will an AI agent use up my Walmart Marketplace API limit?

actionlake paces every call to the limits in the Walmart Marketplace service file: 600 calls a minute per connection. Repeated reads are answered from cache (117 Walmart Marketplace actions can be), which never reaches Walmart Marketplace.

What does a Walmart Marketplace action cost?

One upstream call, the only unit actionlake bills. A list that pages bills one call per page (190 Walmart Marketplace actions page). Cache hits, searches, dry runs and calls Walmart Marketplace refused with 401, 403, 429 or a 5xx are free. The Free plan includes 100,000 calls a month with no card. Paid plans start at US$49 a month for 250,000 calls, with overage from US$0.30 down to US$0.18 per 1,000.

Which Walmart Marketplace API does it cover?

The Walmart US Marketplace API v3 (OpenAPI documents from developer.walmart.com/us-marketplace, fetched 2026-10-23) at marketplace.walmartapis.com by default, or the base URL set when you connect. It is built from Walmart Marketplace's documentation as read on 23 October 2026. 190 actions in 72 areas, each one in the signed service file (version 1.0.0).

Does actionlake keep my Walmart Marketplace data, and where?

actionlake processes and stores data in Sydney, Australia; there is no US region yet. Reads may be cached for up to 5 minutes, and a write clears the reads it affects. Each run's request and response is kept, sealed, for your plan's trace window: 1 day on Free, 3 days on Starter, 7 days on Pro, 14 days on Team, 30 days on Business and 30 days on Enterprise. Your Walmart Marketplace credential is sealed under your tenant's key, never logged and never returned. Your traffic is not used to train models.

Which AI clients can use it?

Claude Code, tested by us end to end, and the Claude app as a custom connector, tested by us with an existing key. Other MCP clients that support remote servers over Streamable HTTP (MCP revisions 2025-06-18 and 2025-11-25) and OAuth dynamic client registration, or a bearer header, should connect the same way; we have not tested them. Or plain REST, under the same action names.
