Tools
Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| list_endpointsB | [WalmartMarketplace] List OpenAPI operations with optional filters. |
| describe_endpointA | [WalmartMarketplace] Describe one OpenAPI operation with its schema closure. Returns the operation plus every components.schemas entry reachable from it, so request bodies and responses can be built without the full spec. Server-managed auth and QoS headers are omitted — do not supply them. |
| call_endpointA | [WalmartMarketplace] Execute an authenticated API request. Give operation_id, or method and path together. Auth, WM_MARKET, WM_GLOBAL_VERSION, WM_SANDBOX and correlation headers are added by the server. |
| upload_feedA | [WalmartMarketplace] Upload a feed file for a feed type. Posts the local file as multipart/form-data to /v3/feeds and returns the feed id. |
| download_fileA | [WalmartMarketplace] Download a report, label, or other binary payload to a local path. Give a full url, or operation_id (or method and path). Follows redirects and drops credentials when a redirect leaves Walmart's host. |
| refresh_specsA | [WalmartMarketplace] Refresh bundled OpenAPI specs from the public registry into the user cache, which then takes precedence over the bundled copies. |

TDQS
Scored across 6 tools
Each tool has a clearly distinct purpose: listing/describing endpoints for discovery, calling endpoints for execution, uploading feeds, refreshing specs, and downloading binaries. No overlapping responsibilities that could cause misselection.
All tool names follow a consistent verb_noun pattern in snake_case (list_endpoints, describe_endpoint, call_endpoint, upload_feed, refresh_specs, download_file). The convention is uniform and predictable.
With 6 tools, the server is well-scoped for its purpose of interfacing with a large external API. Each tool earns its place, covering discovery, generic execution, and targeted conveniences without redundancy or bloat.
The call_endpoint tool provides generic access to all Walmart Marketplace operations, ensuring no dead ends. The other tools handle spec discovery, feed uploads, and binary downloads, covering the full lifecycle without significant gaps.
