eBay Fulfillment API MCP Server for AI Agents

This n8n workflow transforms the eBay Fulfillment API into a fully functional MCP server, exposing 15 critical endpoints to AI agents without custom coding. It covers 6 order operations—like retrieving orders, shipping fulfillments, and issuing refunds—and 8 payment dispute actions, such as accepting disputes, adding evidence, and fetching activity details. The MCP trigger node acts as the entry point, routing requests to dedicated HTTP nodes that interact with eBay's API at https://api.ebay.com.

AI expressions with $fromAI() placeholders automatically handle dynamic parameters from agent inputs, ensuring responses flow back natively. Setup is straightforward: import the workflow, add eBay credentials, activate it, and use the webhook URL to connect agents. This eliminates the need for complex API wrappers or server management.

Benefits include massive time savings for eBay sellers automating fulfillment, dispute resolution, and order tracking with AI tools. Use cases span AI-driven e-commerce ops: auto-process shipments, intelligently handle refunds based on dispute data, monitor order statuses in real-time, and scale operations via agent swarms. Ideal for high-volume sellers integrating with tools like Claude or custom LLMs for intelligent automation.
