PEX MCP Server

A Model Context Protocol (MCP) server that provides access to the PEX Card External API. Use this server to let AI assistants like Claude interact with your PEX business account, cards, transactions, and more.

Getting Your PEX API Token

To use the PEX MCP Server, you need a PEX API token. Follow these steps to generate one:

Log in to the PEX Dashboard using your credentials.
Navigate to Profile > Authorized Apps (or go directly to /account/authorized-apps).
Find the PEX MCP Server application and click on it.
Click Generate Token and copy the token value.

Note: Keep your API token secure. Do not commit it to version control or share it publicly.

Configuration

Set the following environment variables:

Variable	Required	Description
`PEX_API_URL`	Yes	PEX API base URL (e.g., `https://coreapi.pexcard.com/v4`)
`PEX_API_TOKEN`	Yes	Your PEX API token (see Getting Your PEX API Token)

Usage with Claude Desktop

Add to your claude_desktop_config.json:

{
  "mcpServers": {
    "pex": {
      "command": "npx",
      "args": ["-y", "@pexcard_engineering/mcp"],
      "env": {
        "PEX_API_URL": "https://coreapi.pexcard.com/v4",
        "PEX_API_TOKEN": "your-api-token-here"
      }
    }
  }
}

Config file locations

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
Windows: %APPDATA%\Claude\claude_desktop_config.json

Usage with Claude Code (CLI)

Add the MCP server using the Claude Code CLI:

claude mcp add pex -e PEX_API_URL=https://coreapi.pexcard.com/v4 -e PEX_API_TOKEN=your-api-token-here -- npx -y @pexcard_engineering/mcp

Or add it manually to your .claude/settings.json:

{
  "mcpServers": {
    "pex": {
      "command": "npx",
      "args": ["-y", "@pexcard_engineering/mcp"],
      "env": {
        "PEX_API_URL": "https://coreapi.pexcard.com/v4",
        "PEX_API_TOKEN": "your-api-token-here"
      }
    }
  }
}

Usage with GitHub Copilot

VS Code

Add the following to your VS Code settings (.vscode/settings.json or user settings):

{
  "github.copilot.chat.mcpServers": {
    "pex": {
      "command": "npx",
      "args": ["-y", "@pexcard_engineering/mcp"],
      "env": {
        "PEX_API_URL": "https://coreapi.pexcard.com/v4",
        "PEX_API_TOKEN": "your-api-token-here"
      }
    }
  }
}

Alternatively, create an .mcp.json file in your project root:

{
  "servers": {
    "pex": {
      "command": "npx",
      "args": ["-y", "@pexcard_engineering/mcp"],
      "env": {
        "PEX_API_URL": "https://coreapi.pexcard.com/v4",
        "PEX_API_TOKEN": "your-api-token-here"
      }
    }
  }
}

Tip: When using .mcp.json, add it to your .gitignore if it contains your actual token, or use environment variable references to keep secrets out of source control.
