Connect AI Agents to eBay Compliance API for Listing Violation Management

This n8n workflow creates a complete MCP (Model Context Protocol) server that bridges AI agents with eBay's Compliance API, specifically handling three key operations: retrieving violation summary counts (GET /listing_violation), fetching detailed listing violation counts for sellers (GET /listing_violation_summary), and suppressing listing violations (POST /suppress_listing_violation). It uses an MCP Trigger node as the entry point, HTTP Request nodes to interact with eBay's API at https://api.ebay.com, and AI expressions like $fromAI() for seamless parameter population from AI inputs.

Benefits include effortless integration of AI-driven automation into eBay seller workflows, reducing manual compliance checks and violation resolutions. Error handling is built-in via n8n's HTTP nodes, ensuring robust responses back to AI agents in native API format. This saves significant time for high-volume sellers by automating violation monitoring and suppression.

Ideal use cases: eBay power sellers using AI tools (e.g., custom agents or LLMs) to proactively scan listings, get violation alerts, and auto-suppress issues; inventory managers integrating compliance into broader automation pipelines; or agencies handling multiple seller accounts for scalable violation management.
