MCP server for [Walmart Connect Ads APIs](https://developer.walmart.com/advertising-partners) — Sponsored Search and Display.
MCP Walmart Ads MCP server is a locally run integration for AI assistants that speak the Model Context Protocol. MCP server for Walmart Connect Ads APIs — Sponsored Search and Display.
Once MCP Walmart Ads is connected, these are the calls the assistant has available:
list_endpoints — List operations from the bundled OpenAPI spec for an ad_type, with optional filtersdescribe_endpoint — Return one operation plus the components.schemas reachable from it (its $ref closure), so request bodies and responses can be built without the fullcall_endpoint — Execute any Walmart Connect Ads API endpoint. Identify it by operation_id, or by raw method + path. Raw method+path also reachesrefresh_specs — Re-fetch the bundled OpenAPI specs from ReadMe's public api-registry into a user cache (~/.cache/mcp-walmart-ads/specs/) that takes precedence overdownload_display_snapshot — Download a display snapshot file (report or entity). Display snapshot URLs require authenticated requests, so this tool handles the signingCursor — The Cursor tool exposed by this serverCodex — The Codex tool exposed by this serverOpenCode — The OpenCode tool exposed by this serverInstallation goes through your MCP client rather than a global install: point it at @modelcontextprotocol/inspector on npm and it is fetched when the client starts. The copy-paste blocks for Claude Desktop, Claude Code and Cursor are further down this page.
This sits in the developer tooling group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. MCP Walmart Ads's toolset — list_endpoints, describe_endpoint, call_endpoint and 5 more — is a fair guide to whether it matches your workflow. It is maintained by alyiox; worth a glance at recent repository activity before you build anything load-bearing on it.
