MCP Emtrafesa

A Model Context Protocol (MCP) server for accessing Emtrafesa bus transportation services in Peru

• English: README.md (You are here)
• Español: README.es.md

MCP Emtrafesa is a Model Context Protocol server that provides AI assistants with seamless access to Peru's Emtrafesa bus transportation system. Query terminals, schedules, tickets, and FAQs through standardized MCP tools.

What can you do with this MCP?

• Find bus terminals across Peru
• Check schedules between any two cities
• Look up your purchased tickets using your DNI and email
• Download your ticket as PDF for printing or sharing
• Get answers to frequently asked questions

Quick Start

Option 1: Claude Desktop (Recommended)

Open your Claude Desktop configuration file:

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

Add the following entry:

{
  "mcpServers": {
    "mcp-emtrafesa": {
      "command": "npx",
      "args": ["mcp-emtrafesa@latest"]
    }
  }
}

Restart Claude Desktop. You'll see an MCP indicator in the bottom-right corner of the chat input when the server is connected.

Option 2: Clone and run locally

# Clone the repository
git clone https://github.com/georgegiosue/mcp-emtrafesa.git
cd mcp-emtrafesa

# Install dependencies
bun install

Then point your MCP client to the local server:

{
  "mcpServers": {
    "mcp-emtrafesa": {
      "command": "bun",
      "args": ["/absolute/path/to/mcp-emtrafesa/src/index.ts"]
    }
  }
}

Tip: Use the MCP Inspector for debugging: bunx @modelcontextprotocol/inspector bun src/index.ts

Available Tools

Usage Examples

Once connected, you can ask Claude naturally:

• "What bus terminals does Emtrafesa have?"
• "What schedules are available from Chiclayo to Trujillo on 14/07/2025?"
• "Look up my tickets with DNI 12345678 and email user@example.com"
• "Download the PDF for ticket BP01-123456"

Requirements

• Bun v1.2.10+ or Node.js v18+
• An MCP-compatible client (Claude Desktop, etc.)
