Prerequisites
Before connecting Cursor, ensure you have:
Installation
Install Cursor
Download and install Cursor for your operating system: Download Link: cursor.sh Available for:
macOS (Intel and Apple Silicon)
Windows
Linux
Cursor is free to use with a Pro plan available for advanced features
Locate Configuration File
Find your Cursor MCP configuration file location: ~ /Library/Application Support/Cursor/User/globalStorage/mcp.json
Or check Cursor settings location: ~ /Library/Application Support/Cursor/User/settings.json
To open in Finder: open ~/Library/Application \ Support/Cursor/User/globalStorage/
In recent Cursor versions, MCP configuration might be in:
~/.cursor/mcp_settings.json or configured via Settings UI
%APPDATA%\Cursor\User\globalStorage\mcp.json
Or: %APPDATA%\Cursor\User\settings.json
To open in Explorer: explorer %APPDATA% \C ursor \U ser \g lobalStorage
~ /.config/Cursor/User/globalStorage/mcp.json
Or: ~ /.config/Cursor/User/settings.json
To open in file manager: xdg-open ~/.config/Cursor/User/globalStorage/
MCP configuration location may vary by Cursor version. Check Cursor’s documentation or settings UI for the current location.
Configure via Settings UI (Recommended)
Cursor provides a settings interface for MCP configuration:
Open Cursor
Go to Settings (Cmd/Ctrl + ,)
Search for “MCP” or “Model Context Protocol”
Click “Edit in settings.json”
Add the eBay MCP Server configuration: {
"mcp.servers" : {
"ebay" : {
"command" : "node" ,
"args" : [ "/absolute/path/to/ebay-mcp-server/build/index.js" ],
"env" : {
"EBAY_CLIENT_ID" : "YourAppId-12345" ,
"EBAY_CLIENT_SECRET" : "YourCertId-67890" ,
"EBAY_ENVIRONMENT" : "sandbox" ,
"EBAY_REDIRECT_URI" : "http://localhost:3000/callback"
}
}
}
}
Important:
Replace /absolute/path/to/ebay-mcp-server with your actual installation path
Use absolute paths , not relative paths
Replace the example credentials with your actual eBay Developer credentials
Example paths:
macOS: /Users/yourname/ebay-mcp-server/build/index.js
Windows: C:\\Users\\yourname\\ebay-mcp-server\\build\\index.js
Linux: /home/yourname/ebay-mcp-server/build/index.js
Add User Tokens (Optional but Recommended)
For full API access and higher rate limits, add user tokens: {
"mcp.servers" : {
"ebay" : {
"command" : "node" ,
"args" : [ "/absolute/path/to/ebay-mcp-server/build/index.js" ],
"env" : {
"EBAY_CLIENT_ID" : "YourAppId-12345" ,
"EBAY_CLIENT_SECRET" : "YourCertId-67890" ,
"EBAY_ENVIRONMENT" : "sandbox" ,
"EBAY_REDIRECT_URI" : "http://localhost:3000/callback" ,
"EBAY_USER_ACCESS_TOKEN" : "v^1.1#i^1#..." ,
"EBAY_USER_REFRESH_TOKEN" : "v^1.1#i^1#..." ,
"EBAY_USER_TOKEN_EXPIRY" : "2025-12-31T23:59:59.000Z"
}
}
}
}
Run the setup wizard in your eBay MCP Server directory: cd /path/to/ebay-mcp-server
npm run setup
The wizard will:
Guide you through OAuth authorization
Generate user access and refresh tokens
Save tokens to your .env file
Then copy the token values from .env to your Cursor settings. Rate Limits:
Without user tokens: 1,000 requests/day (client credentials)
With user tokens: 10,000-50,000 requests/day
Reload Cursor
Open the Command Palette (Cmd/Ctrl + Shift + P)
Type “Reload Window” and select it
Or simply restart Cursor
After reloading, Cursor will connect to the eBay MCP Server
Alternative: Configuration File Method
If your Cursor version uses a dedicated MCP configuration file:
Create MCP Configuration
Create or edit the MCP configuration file (location varies by version): Common locations:
~/.cursor/mcp_settings.json (macOS/Linux)
%USERPROFILE%\.cursor\mcp_settings.json (Windows)
Or check Cursor documentation for your version
Add this configuration: {
"mcpServers" : {
"ebay" : {
"command" : "node" ,
"args" : [ "/absolute/path/to/ebay-mcp-server/build/index.js" ],
"env" : {
"EBAY_CLIENT_ID" : "YourAppId-12345" ,
"EBAY_CLIENT_SECRET" : "YourCertId-67890" ,
"EBAY_ENVIRONMENT" : "sandbox"
}
}
}
}
Verify Configuration
Check that the file is valid JSON: # Validate JSON syntax
python -m json.tool ~/.cursor/mcp_settings.json
Or use an online validator like jsonlint.com
Verification
Test your connection to ensure everything is working:
Check Cursor AI Chat
Open Cursor AI chat (Cmd/Ctrl + L or click the chat icon)
Look for an indication that MCP tools are loaded
You may see “230+ tools available” or similar
Test Basic Query
In the Cursor AI chat, try:
“Can you list my eBay fulfillment policies using the MCP tools?”
Cursor should use the getFulfillmentPolicies tool and return your configured policies.
Verify in Code
You can also use Cursor’s inline chat while coding:
Open any file in Cursor
Use Cmd/Ctrl + K (inline chat)
Type: “Show my eBay inventory items”
Cursor will call the eBay MCP tools and show results.
Success! You now have eBay automation capabilities directly in your code editor.
Usage Examples
Here are practical ways to use eBay MCP with Cursor:
Building eBay Integrations
Generate code for creating listings
Prompt in Cursor chat:
“Write a TypeScript function to create an eBay listing using the MCP tools. It should accept product details and create both the inventory item and offer.”
What happens:
Cursor will:
Use eBay MCP tools to understand the API structure
Generate TypeScript code that uses createOrReplaceInventoryItem and createOffer
Include proper error handling and types
Debug eBay Sell APIs integration
Scenario: Your code for fetching orders isn’t workingPrompt:
“My eBay order fetching code is failing. Can you use the getOrders tool to show me what the actual API response looks like?”
What happens:
Cursor uses getOrders to fetch real data and helps you fix your code based on the actual response structure.
Generate API documentation
Prompt:
“Generate documentation for all available eBay inventory management tools”
What happens:
Cursor will enumerate eBay inventory tools and create markdown documentation with parameters and usage examples.
Quick eBay Operations
Check order status while coding
Inline chat (Cmd/Ctrl + K):
“Are there any new orders today?”
What happens:
Cursor uses getOrders with today’s date filter and shows results inline.
Update listings during development
Chat prompt:
“Update the price of SKU LAPTOP-001 to $599.99”
What happens:
Cursor uses updateOffer to change the price, useful when testing price update features.
Automated Scripts
Generate bulk update script
Prompt:
“Create a Node.js script that increases all my product prices by 10% using the eBay MCP tools”
What happens:
Cursor generates a script that:
Fetches all inventory items
Calculates new prices
Updates each offer
Includes progress logging and error handling
Configuration Options
Multiple MCP Servers in Cursor
Run multiple MCP servers alongside eBay:
{
"mcp.servers" : {
"ebay" : {
"command" : "node" ,
"args" : [ "/path/to/ebay-mcp-server/build/index.js" ],
"env" : {
"EBAY_CLIENT_ID" : "your_id" ,
"EBAY_CLIENT_SECRET" : "your_secret" ,
"EBAY_ENVIRONMENT" : "sandbox"
}
},
"filesystem" : {
"command" : "npx" ,
"args" : [ "-y" , "@modelcontextprotocol/server-filesystem" , "/path/to/allowed/directory" ]
},
"github" : {
"command" : "npx" ,
"args" : [ "-y" , "@modelcontextprotocol/server-github" ],
"env" : {
"GITHUB_TOKEN" : "your_github_token"
}
}
}
}
Environment-Specific Configurations
Maintain separate configurations for different environments:
Sandbox (Testing)
Production (Live)
Both Environments
{
"mcp.servers" : {
"ebay-sandbox" : {
"command" : "node" ,
"args" : [ "/path/to/ebay-mcp-server/build/index.js" ],
"env" : {
"EBAY_CLIENT_ID" : "SBX-AppId-12345" ,
"EBAY_CLIENT_SECRET" : "SBX-CertId-67890" ,
"EBAY_ENVIRONMENT" : "sandbox"
}
}
}
}
{
"mcp.servers" : {
"ebay-production" : {
"command" : "node" ,
"args" : [ "/path/to/ebay-mcp-server/build/index.js" ],
"env" : {
"EBAY_CLIENT_ID" : "PRD-AppId-12345" ,
"EBAY_CLIENT_SECRET" : "PRD-CertId-67890" ,
"EBAY_ENVIRONMENT" : "production" ,
"EBAY_USER_ACCESS_TOKEN" : "v^1.1#i^1#..." ,
"EBAY_USER_REFRESH_TOKEN" : "v^1.1#i^1#..."
}
}
}
}
Production configuration affects real listings and transactions. Test thoroughly in Sandbox first.
{
"mcp.servers" : {
"ebay-sandbox" : {
"command" : "node" ,
"args" : [ "/path/to/ebay-mcp-server/build/index.js" ],
"env" : {
"EBAY_CLIENT_ID" : "SBX-AppId" ,
"EBAY_CLIENT_SECRET" : "SBX-CertId" ,
"EBAY_ENVIRONMENT" : "sandbox"
}
},
"ebay-production" : {
"command" : "node" ,
"args" : [ "/path/to/ebay-mcp-server/build/index.js" ],
"env" : {
"EBAY_CLIENT_ID" : "PRD-AppId" ,
"EBAY_CLIENT_SECRET" : "PRD-CertId" ,
"EBAY_ENVIRONMENT" : "production"
}
}
}
}
Access each environment by referring to the server name in your prompts.
Advanced Logging
Enable detailed logging for debugging:
{
"mcp.servers" : {
"ebay" : {
"command" : "node" ,
"args" : [ "/path/to/ebay-mcp-server/build/index.js" ],
"env" : {
"EBAY_CLIENT_ID" : "your_id" ,
"EBAY_CLIENT_SECRET" : "your_secret" ,
"EBAY_ENVIRONMENT" : "sandbox" ,
"LOG_LEVEL" : "debug" ,
"LOG_REQUESTS" : "true"
}
}
}
}
Troubleshooting
MCP tools not appearing in Cursor
Error: Cannot find module
Cause: The eBay MCP Server hasn’t been built yet.Solution: cd /path/to/ebay-mcp-server
npm install
npm run build
Verify build/index.js exists after building.
Error: Invalid credentials
Cause: eBay Client ID or Secret is incorrect.Solution:
Verify credentials in eBay Developer Portal
Ensure you’re using the correct environment (Sandbox vs Production)
Check for typos in your settings
Remove any extra spaces or quotes around values
Tools visible but API calls fail
Cursor becomes slow or unresponsive
Cause: MCP server startup issues or too many concurrent requests.Solutions:
Check if server starts correctly:
cd /path/to/ebay-mcp-server
npm start
Look for errors in Cursor’s Developer Tools (Help → Toggle Developer Tools)
Temporarily disable eBay MCP server in settings
Restart Cursor
Re-enable with simpler configuration
Cause: Exceeded daily API request limit.Solution:
Using client credentials? Add user tokens for 10-50x higher limits
Already using user tokens? Wait 24 hours or upgrade your eBay seller account
Reduce the number of API calls in your scripts
Implement caching for frequently accessed data
Best Practices
Use Sandbox for Development Always test in Sandbox environment when developing eBay integrations to avoid affecting real listings.
Add User Tokens Configure user tokens for full API access and higher rate limits (10,000-50,000 requests/day).
Version Control Safety Never commit MCP settings with credentials to version control. Use environment variables or separate config files.
Separate Environments Configure both Sandbox and Production servers with distinct names to avoid accidental production changes.
Viewing Logs
Check Cursor and server logs for debugging:
Cursor Output Panel
Developer Console
Server Logs
Open Cursor
Go to View → Output
Select “Model Context Protocol” from the dropdown
Look for eBay MCP server connection logs
Open Developer Tools: Help → Toggle Developer Tools
Check Console tab for JavaScript errors
Check Network tab for MCP communication issues
If you enabled logging in your configuration: # Check server output
cd /path/to/ebay-mcp-server
npm start
# Or check log files if configured
tail -f /path/to/ebay-mcp-server/logs/server.log
