Which MCP Server Should You Choose?
Choose Walmart Connect Advertising APIs when:
You need dedicated capabilities in the Developer Tools domain.
You prefer local stdio subprocess transport architecture.
Your security boundary fits: No auth required (Free / Open Source).
List operations from the bundled OpenAPI spec for an `ad_type`, with optional filters.
describe_endpoint
Return one operation plus the `components.schemas` reachable from it (its `$ref` closure), so request bodies and responses can be built without the full spec.
call_endpoint
Execute any Walmart Connect Ads API endpoint. Identify it by `operation_id`, or by raw `method` + `path`. Raw method+path also reaches alpha/beta/unpublished endpoints that are not in the bundled specs. The server handles RSA-SHA256 signing.
refresh_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 over the bundled copy.
download_display_snapshot
Download a display snapshot file (report or entity). Display snapshot URLs require authenticated requests, so this tool handles the signing automatically. Use the full download URL from the `details` field after polling a display snapshot to `done` status.
Ready-to-Paste Client Configurations
Paste either (or both) of these JSON server blocks into your client config file (e.g. claude_desktop_config.json or ~/.cursor/mcp.json).
Walmart Connect Advertising APIs is categorized under Developer Tools and uses a local stdio subprocess. In contrast, Openapi MCP Server belongs to Developer Tools using remote streaming HTTP/SSE transport. Select Walmart Connect Advertising APIs when you need capabilities focused on developer tools and Openapi MCP Server when you require tools for developer tools.
