Action MCP Example 🚀

A simple Ruby on Rails application demonstrating how to integrate and use ActionMCP.

Requirements

• Ruby (see .ruby-version for recommended version)
• PostgreSQL (or Docker)

Getting Started

1. Clone and Setup

git clone https://github.com/seuros/mcp_rails_template.git
cd mcp_rails_template
bin/setup

2. Environment Configuration

Copy the provided .env.example file:

cp .env.example .env

Edit .env and fill in necessary values according to your setup.

3. Database Setup

You can quickly spin up a temporary PostgreSQL instance using Docker:

make up

This will start PostgreSQL on port 5466.

Alternatively, configure your own PostgreSQL database by editing config/database.yml.

4. Run the Application

Launch the Rails server:

bin/rails s

The app will be available at http://localhost:3002.

ActionMCP Engine

By default, the ActionMCP engine is mounted at /action_mcp. Feel free to mount it at a custom location by modifying the routes in your application.

Usage

The app includes a simple tool to lint Ruby code using RuboCop through ActionMCP.

To test and inspect MCP functionality interactively, run:

npx @modelcontextprotocol/inspector
