MCP server for AI agents: real-time access to eBay API

This automation template enables AI agents to securely and dynamically access real-time rate limit data from the eBay API. It helps prevent quota overuse by allowing agents to check available calls before executing operations. The integration is built using an HTTP-triggered MCP server and runs on n8n.

## Who it´s for
- Developers integrating AI agents with eBay API
- SaaS companies using eBay in their products
- Automation specialists monitoring API quota usage
- AI engineers configuring external tools for agents

## What the automation does
- Receives requests from AI agents via an MCP trigger (HTTP API)
- Determines the limit type: application-level or user-level
- Dynamically populates request parameters from agent input using $fromAI() expressions
- Sends authenticated requests to eBay Analytics API using OAuth2
- Returns current quota data: used/remaining calls, reset time

## What´s included
- Ready-to-use n8n workflow
- Logic for handling MCP requests from LangChain-compatible agents
- Integrations with eBay API and external AI agents via HTTP
- Basic textual guide for setup and adaptation

## Requirements for setup
- n8n instance with HTTP trigger access
- OAuth2-authorized eBay API credentials
- LangChain-compatible AI agent capable of calling external MCP tools

## Benefits and outcomes
- Prevents API rate limit errors
- Increases reliability of AI agents interacting with eBay
- Centralized control over API quota consumption
- Enables operation planning based on available API resources
- Reduces developer workload through automated limit checks
