Sam's Club Sponsored Ads APIs (deprecated)

alyiox/mcp-walmart-ads

Connects to Walmart Connect's Sponsored Search and Display advertising APIs with automatic RSA-SHA256 request signing. You get two tools: a generic API proxy that hits any endpoint (campaigns, ad groups, keywords, audiences, reports) and a display snapshot downloader for pulling report files. The server bundles API reference docs as MCP resources so your agent knows the schemas without external lookups. Handles multi-region and staging environments through a config file in your home directory. Useful if you're managing Walmart ad campaigns programmatically and need authenticated access to their partner APIs without building the signing flow yourself.
