MCP Logo MCP Emtrafesa

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

CI codecov NPM Version TypeScript Bun MCP License: MIT

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

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
