How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score → Why this is hard to score →
Supply Chain Security100

Schema Quality & AI Usability76
- 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 1497 tokens (~299/item across 5 items; 4 tools + 1 resources), over budget; trim descriptions and params. See how to fix → Fail

- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 4 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 6 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
call_endpoint ~488
[Walmart] Execute an authenticated API request. Identify the endpoint by operation_id, or by method + path with an api — a raw path also reaches alpha/beta/unpublished endpoints absent from the bundled specs. Auth, signature, market, and correlation headers are added by the server. A body over the configured threshold is truncated to a preview; read the returned cached_at resource for the whole of it.
| Name | Type | Req | Description |
|---|---|---|---|
| advertiser_id | – | – | Required on walmart:marketplace, where it selects the credential to act as. On the ads platforms it is optional and sent as X-Advertiser-ID, which many display/creative/campaign endpoints require. Sr… |
| api | – | – | Api to call, e.g. walmart:marketplace:order-management. Required with raw method+path; otherwise inferred from operation_id. Src: platforms. |
| body | – | – | JSON request body for POST/PUT/PATCH — an object, or an array of objects where the API takes a batch. |
| environment | string | yes | Target environment. walmart:marketplace accepts production or sandbox; the ads platforms accept whatever the config declares, usually production or staging. Src: platforms. |
| file_path | – | – | Local file to send as multipart/form-data instead of a JSON body — Marketplace feed uploads. Pair with the feedType query parameter. |
| method | – | – | HTTP method. Required unless operation_id is given. |
| operation_id | – | – | Operation id, qualified as api:operationId (e.g. walmart:ads:sponsored-products:SBAProfileUpdateV2) or bare when unambiguous. Resolves the api, platform, method, path, and required headers. Src: oper… |
| params | – | – | Query string parameters as a JSON object. |
| path | – | – | API path after the base URL, e.g. /v3/orders or /api/v1/campaigns. Required unless operation_id is given. |
| path_params | – | – | Values for {placeholders} in the path, e.g. {"purchaseOrderId": "1796277083022"}. |
| region | string | yes | Region label, e.g. us. Src: platforms. |
| tenant | – | – | WAP tenant for non-US walmart:ads regions, e.g. WMT_CA, WMT_MX, WBD_OD. Omit for US and for walmart:marketplace. Sent as wap-tenant-id. |
| Name | Type | Req | Description |
|---|---|---|---|

| cached_at | – | – | – |
| curl | – | – | – |
| error | – | – | – |
| status_code | – | – | – |
| truncated | – | – | – |
No examples provided.
describe_endpoint ~110
[Walmart] Describe one OpenAPI operation. Returns it with every components.schemas entry reachable from it, so a request body can be built without the full spec.
| Name | Type | Req | Description |
|---|---|---|---|
| api | – | – | Api to resolve a bare operation_id in, e.g. walmart:ads:sponsored-products. Src: platforms. |
| operation_id | string | yes | Operation id, qualified as api:operationId (e.g. walmart:marketplace:order-management:getAllOrders) or bare when unambiguous. Src: operations. |
Structured output declared, but exposes no named fields.
No examples provided.
download_file ~366
[Walmart] Download a report, label, or snapshot. Give a full url — such as the `details` URL from a display snapshot poll, or a Marketplace report url — or an operation_id, or an api with method and path. Written to dest_path when given, otherwise gunzipped and cached. Redirects are followed for you.
| Name | Type | Req | Description |
|---|---|---|---|
| advertiser_id | – | – | Required on walmart:marketplace (selects the credential) and by display snapshot downloads, where it is sent as X-Advertiser-ID and as the advertiserId query parameter. Src: platforms. |
| api | – | – | Api to call when using method+path. Src: platforms. |
| dest_path | – | – | Local path to write the bytes to. Omit to gunzip and cache the payload instead, readable at the returned cached_at resource. |
| environment | string | yes | Target environment. walmart:marketplace accepts production or sandbox; the ads platforms accept whatever the config declares, usually production or staging. Src: platforms. |
| method | – | – | HTTP method when using path. Defaults to GET. |
| operation_id | – | – | Operation id, qualified or bare. Src: operations. |
| params | – | – | Query string parameters as a JSON object. |
| path | – | – | API path when not using url. |
| path_params | – | – | Values for {placeholders} in path. |
| platform | – | – | Platform to authenticate as. Required with a bare url; otherwise inferred from operation_id or api. Src: platforms. |
| region | string | yes | Region label, e.g. us. Src: platforms. |
| tenant | – | – | WAP tenant for non-US walmart:ads regions. Sent as wap-tenant-id. |
| url | – | – | Absolute URL to fetch, e.g. a snapshot or report URL returned by a previous call. |
| Name | Type | Req | Description |
|---|---|---|---|
| bytes_written | – | – | – |
| cached_at | – | – | – |
| content_type | – | – | – |
| error | – | – | – |
| path | – | – | – |
| size_bytes | – | – | – |
| status_code | – | – | – |
| urls | – | – | – |
No examples provided.
list_endpoints ~165
[Walmart] List OpenAPI operations across every api. Returned operation ids can be passed straight to describe_endpoint or call_endpoint.
| Name | Type | Req | Description |
|---|---|---|---|
| api | – | – | Limit to one api, e.g. walmart:marketplace:order-management. A platform prefix is not accepted here — use platform for that. Src: platforms. |
| limit | integer | – | Rows to return from offset. The largest single api has 87. |
| method | – | – | Filter by HTTP verb. |
| offset | integer | – | Rows to skip. Pass next_offset from a prior call. |
| platform | – | – | Limit to one platform. Src: platforms. |
| query | – | – | Case-insensitive substring match on operation id, path, or summary. |
| tag | – | – | Filter to operations whose OpenAPI tags include this value. |
Structured output declared, but exposes no named fields.
