ADSMCP checks the arguments and stages the change as a pending action. It runs only after a person approves it on the dashboard [Approvals](https://adsmcp.si/dashboard/approvals) page. Over MCP or REST you can view (`list_pending_actions`) or reject (`manage_action`) it, never approve it. `execution_mode` and similar arguments do not skip the queue. > > A change that fails when it runs is not retried automatically. It shows on the dashboard Execution Queue. Upload an image (png, jpg or gif, at most 1024 KiB) to the Amazon creative asset library, for example a brand logo for Sponsored Brands. Send the bytes base64-encoded; no URL is fetched by ADSMCP. Amazon registers it after approval. Staged for dashboard approval; nothing changes in Amazon before a person approves it. **Platform:** Amazon Ads · **Type:** Change ## How to call it * **MCP:** on `https://mcp.adsmcp.si/mcp`, run it through the `amazon_ads_write` tool with `{"action": "execute", "tool_name": "upload_amazon_asset", "arguments": { ... }}`, or call `upload_amazon_asset` by name. `search_tools` finds it and `get_tool_schema` returns its arguments; `https://mcp.adsmcp.si/mcp/flat` lists every tool by name. * **REST:** `POST https://mcp.adsmcp.si/api/v1/tools/upload_amazon_asset/execute` with `Authorization: Bearer sk_live_...` and a JSON body `{"platform": "amazon", "arguments": { ... }}`. The arguments are listed below; they are exactly the tool's input schema. ## OpenAPI ````yaml api-reference/openapi.json POST /api/v1/tools/upload_amazon_asset/execute openapi: 3.1.0 info: title: ADSMCP REST API version: 0.1.0 description: >- ADSMCP REST API: every public ADSMCP tool as POST /api/v1/tools/{name}/execute.
