What is the Rails MCP Server?

The Rails MCP Server is a tool that implements the Model Context Protocol (MCP) standard, enabling large language models (LLMs) to interact with Rails projects. Through this server, AI models can browse project files, analyze database schemas, view route definitions, and obtain model information.

How to use the Rails MCP Server?

First, install and configure the server, then start it, and finally connect via an MCP-supported client and begin exploring your Rails project.

Use Cases

The Rails MCP Server is suitable for developers who want to enhance the AI integration capabilities of their Rails projects, such as for code analysis, model optimization, or auxiliary development.

Main Features

Multi-Project ManagementSupports switching and management of multiple Rails projects.

File BrowsingAllows browsing of files and directory structures in the project.

Route ViewingDisplays all defined HTTP routes and their associated controllers.

Model Information AnalysisProvides detailed information about Active Record models, including associations and database schemas.

Environment Configuration AnalysisChecks whether the environment variable configuration is consistent and secure.

Advantages and Limitations

Advantages

Supports the standardized Model Context Protocol.

Easy to integrate into existing Rails projects.

Provides various tools for in-depth analysis of the project structure.

Limitations

Requires a certain amount of Ruby and Rails knowledge to fully utilize its features.

May have a certain impact on environments with high performance requirements.

Standard Input/Output (STDIO) mode (default):

bin/rails-mcp-server

HTTP mode:

bin/rails-mcp-server --mode http

💻 Usage Examples

Basic Usage

All tools are executed through the tool_calls method of the MCP protocol.

Project Analysis

# Analyze the entire Rails project
tool_calls :analyze_rails_project, project_path: "."

# List all available tools
tool_calls :list_tools

Database Schema Analysis

# Get the complete database schema
tool_calls :get_schema

# Get detailed information about a specific table
tool_calls :get_schema, table_name: "users"

Advanced Usage

Environment Configuration Analysis

Integration with LLM Clients

To use a client that supports the MCP protocol (e.g., Claude Desktop), follow these steps:

Start the Rails MCP Server.
Connect the client to the server.
Use the available tools for project analysis.

Testing and Debugging

Using the MCP Inspector

The MCP Inspector is a developer tool designed for testing and debugging. Here's how to use it:

Install the inspector:

npm install -g @modelcontextprotocol/inspector

Start the inspector and connect to the Rails MCP Server:

npx @modelcontextprotocol/inspector /path/to/rails-mcp-server

Access the default address (http://localhost:6274) in your browser to start interactive calls and debugging.
