Model Context Protocol (MCP) servers have emerged as powerful tools that bridge AI assistants with specialized knowledge sources. These servers enable AI tools to access structured information about APIs, documentation, and schemas, making development more efficient and accurate.
MCP servers fundamentally transform how developers work with APIs by providing AI assistants with direct access to specifications, documentation, and functionality. Instead of constantly switching between documentation and code, developers can leverage AI to generate code, understand API structures, and execute operations—all while maintaining perfect alignment with actual API specifications.
The PayPal MCP Server exemplifies this approach by connecting AI assistants directly to PayPal's business functionality. This server allows AI tools to create and manage invoices, access transaction data, and perform other PayPal operations through natural language instructions.
Key benefits of using MCP servers include:
- Reduced context switching between documentation and code
- Improved accuracy with generated code that aligns with API specifications
- Faster development through automatic generation of common patterns
- Natural language interaction with complex API systems
- Consistent implementation that remains aligned with documentation
For teams working with multiple APIs, combining different MCP servers creates a powerful development environment where AI assistants have comprehensive knowledge across various API ecosystems.
Pro Tip: While PayPal MCP Server offers excellent capabilities for PayPal-specific operations, pairing it with Apidog MCP Server creates a powerful unified environment for all your API needs. Apidog MCP Server provides AI access to your custom API specifications, enabling seamless development across both PayPal and your own APIs.
Exploring PayPal MCP Server Capabilities
PayPal's MCP Server provides specialized tools that enable AI assistants to interact directly with PayPal's business functionality. This powerful integration allows developers to perform PayPal operations through natural language instructions.
Key Features of PayPal MCP Server
PayPal's implementation currently focuses on invoice management:
Invoice Creation: Create PayPal invoices using natural language instructions, specifying recipients, amounts, due dates, and other details without writing code.

}
}
}
}Restart your MCP client to apply the changes
Test the connection by asking your AI assistant to perform a PayPal operation
Option 2: Connecting to PayPal MCP Server Remotely
- Configure your MCP client with the following JSON:
{
"mcpServers": {
"paypal-mcp-server": {
"command": "npx",
"args": [
"mcp-remote",
"https://mcp.paypal.com/sse"
]
}
}
}Restart your MCP client - it will redirect you to the PayPal login page
Authenticate with PayPal:
- Log into your PayPal account
- Authorize the MCP client to work with PayPal MCP Server
- Quit and reopen your MCP client
Test the connection by asking your AI assistant to create an invoice
Integrating Apidog MCP Server with PayPal MCP
Combining the PayPal MCP Server with Apidog MCP Server creates a powerful, unified development environment where AI assistants can access both PayPal's functionality and your custom API specifications.
Setting Up Apidog MCP Server
Apidog MCP Server supports three primary data sources:
- Apidog Project: Connect to API specifications within your Apidog team
- Online API Documentation: Access publicly available API documentation published via Apidog
- OpenAPI Files: Read local or online Swagger/OpenAPI files
Prerequisites:
- Node.js (version 18 or higher)
- An Apidog account with access to your API project
- Your Apidog API access token and project ID
Configuration Steps:
Generate an Apidog Access Token:
- Log into your Apidog account
- Navigate to Account Settings > API Access Token
- Create a new token and copy it to a secure location
Locate Your Apidog Project ID:
- Open your project in Apidog
- Go to Settings in the left sidebar
- Find and copy the Project ID from Basic Settings
Combining PayPal and Apidog MCP Servers
To integrate both MCP servers in your AI tool, update your configuration file:
{
"mcpServers": {
"paypal": {
"command": "npx",
"args": [
"-y",
"@paypal/mcp",
"--tools=all"
],
"env": {
"PAYPAL_ACCESS_TOKEN": "YOUR_PAYPAL_ACCESS_TOKEN",
"PAYPAL_ENVIRONMENT": "SANDBOX"
}
},
{
"mcpServers": {
"API specification": {
"command": "npx",
"args": [
"-y",
"apidog-mcp-server@latest",
"--project=<project-id>",
// Required for on-premise deployment:
"--apidog-api-base-url=<API address of the on-premise server, starting with http:// or https://>"
],
"env": {
"APIDOG_ACCESS_TOKEN": "<access-token>"
}
}
}
}Replace YOUR_PAYPAL_ACCESS_TOKEN, <project-id>, and <access-token> with your actual values.
Verifying the Integration
To confirm that both MCP servers are working together:
Ask the AI assistant to perform a PayPal operation:
"Create a PayPal invoice for website development services for $500"Then ask about your custom API in Apidog:
"Fetch my API specification via Apidog MCP and tell me about the available endpoints"Practical Applications: Leveraging PayPal MCP and Apidog MCP
