AI Agent Integration with eBay Buy Marketing API
This n8n workflow demonstrates a foundational setup for integrating AI agents using the Model Context Protocol (MCP) with external services, potentially for an eBay Buy Marketing API use case. While the current workflow is a basic trigger, it lays the groundwork for more complex AI-driven automations.
What it does
This workflow currently provides a starting point for AI agent integrations:
- Listens for AI Agent Requests: It uses an "MCP Server Trigger" node to listen for incoming requests or messages from an AI agent. This trigger acts as the entry point for AI-driven interactions within n8n.
- Provides a Foundation: Although no further actions are defined, this setup is designed to receive context and instructions from an AI agent, which can then be used to trigger subsequent nodes for tasks like interacting with the eBay Buy Marketing API, processing data, or responding to the agent.
Prerequisites/Requirements
- n8n Instance: An active n8n instance where this workflow can be imported and run.
- AI Agent: An AI agent (e.g., built with LangChain or similar frameworks) configured to communicate with the n8n MCP Server Trigger.
Setup/Usage
- Import the Workflow:
- Download the provided JSON file.
- In your n8n instance, click "New" in the workflows list, then "Import from JSON".
- Paste the workflow JSON or upload the file.
- Activate the Workflow:
- Ensure the workflow is activated by toggling the "Active" switch in the top right corner of the workflow editor.
- Configure your AI Agent:
- Configure your AI agent to send requests or messages to the endpoint exposed by the "MCP Server Trigger" node. The exact URL will be displayed in the trigger node's settings once the workflow is active.
- The AI agent will provide the context and data that this workflow will then process.
- Extend the Workflow:
- Add subsequent nodes after the "MCP Server Trigger" to perform actions based on the AI agent's input. For an eBay Buy Marketing API integration, you would add HTTP Request nodes, JSON processing, and potentially other AI nodes to fulfill the agent's requests.

Key settings: pricebook2Id (hardcoded in script): e.g., 01sxxxxxxxxxxxxxxx Source lines: $('Message a model').first().json.message.content.products Output: { soql, codes } --- 8) Query PricebookEntries (Salesforce) Purpose: Fetch PricebookEntry.Id for each Product2.ProductCode. Key settings: Resource: search Query: ={{ $json.soql }} Creds: salesforceOAuth2Api Output: Items with Id, Product2.ProductCode (used for mapping). --- 9) Code in JavaScript (Build OLI payloads) Purpose: Join lines with PBE results and Opportunity Id ➜ build OpportunityLineItem payloads. Inputs: OpportunityId: ={{ $('Create an opportunity').first().json.id }} Lines: ={{ $('Message a model').first().json.message.content.products }} PBE rows: from previous node items Output: { body: { allOrNone:false, records:[{ OpportunityLineItem... }] } } Notes: Converts discount_total ➜ per-unit if needed (currently commented for standard pricing). Throws on missing PBE mapping or empty lines. --- 10) Create Opportunity Line Items (HTTP Request) Purpose: Bulk create OLIs via Salesforce Composite API.

If AI returns non-JSON, keep “Return only a JSON array” as the last line of the prompt and keep jsonOutput enabled. Consider adding validation on parsing.warnings to gate Salesforce writes. For discounts/taxes in OLI: Standard OLI fields don’t support per-line discount amounts directly; model them in UnitPrice or custom fields. Replace the Composite API URL with your org’s domain or use the Salesforce node’s Bulk Upsert for simplicity.
