Walmart Developer Portal MCP Server

Walmart runs a first-party remote MCP server on its developer portal at https://developer.walmart.com/mcp. It answers JSON-RPC over HTTP and is guarded by OAuth 2.1 (authorization-code + PKCE S256, dynamic client registration), advertised through RFC 8414 / RFC 9728 metadata at /.well-known/oauth-authorization-server and /.well-known/oauth-protected-resource. The required scopes are openapi_read and offline_access, which indicates this server exposes the portal's API documentation and OpenAPI definitions to an agent rather than the Marketplace seller runtime (marketplace.walmartapis.com). The tool list is auth-gated: an anonymous tools/list returns JSON-RPC error -32001 "Authentication required", so no tool names or inputSchemas were captured and none are asserted here.

About MCP

The Model Context Protocol (MCP) is an open protocol Anthropic introduced for connecting LLM-based agents to external tools and data sources. Providers publish MCP servers that expose their API surface as structured, discoverable tools — an MCP-compatible client (Claude Desktop, Cursor, Cline, Continue, etc.) can connect to the server and call its tools without any per-provider integration code.

Browse every MCP server on the APIs.io network or compare with the broader Agent Skill surfaces of the same providers.

Work with this as data

Every MCP server here is available over the APIs.io API and to AI agents over MCP.
