This n8n workflow facilitates integration of eBay’s Translation API with AI agents via a custom MCP (Managed Cloud Program) server interface. Its primary goal is to allow AI-driven applications to request language translations—such as translating item titles, descriptions, or search queries—by exposing a dedicated webhook endpoint. The workflow includes a trigger node that listens for incoming requests from AI agents, a setup note detailing how to configure authentication and activate the server, and an HTTP request node that communicates with eBay’s translation API.

Step-by-step, the workflow begins with the MCP trigger node (‘Translation MCP Server’), which acts as the webhook endpoint for incoming translation requests. When an AI agent sends a request to this endpoint, the workflow activates and processes the input.

The ‘Translate Text’ HTTP Request node then takes this input—such as a piece of text needing translation—and sends a POST request to eBay’s translation API at ‘https://api.ebay.com{basePath}/translate’. This node uses OAuth2 credentials for authentication and dynamically populates request parameters with AI expressions (via `$fromAI()`) to customize each request.

Supporting sticky notes provide descriptive instructions and context for users, including setup guidance, available operations, and customization tips.

This workflow is particularly useful for e-commerce platforms, marketplaces, or AI-powered search engines that require real-time language translation of product data or search queries, enhancing user experience across multiple languages.
