Tools & Capabilities Breakdown

Walmart Connect Advertising APIs Tools (5)

list_endpoints

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 Raw method+path also reaches alpha/beta/unpublished endpoints that are not in the bundled specs.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.
