# crisnahine/rails-ai-context

> Stop AI from guessing your Rails app. 35 MCP tools give coding agents ground truth on demand: schema, models, routes, controllers, views, jobs and conventions. Works with Claude Code, Cursor, GitHub Copilot, OpenCode and Codex CLI. MCP or CLI, in your Gemfile or standalone, and it still answers when the app can't boot.

## Project Overview
rails-ai-context is an open-source project written in Ruby: 45 MCP tools that give AI coding agents ground truth about your Rails app: schema, models, routes, controllers, views, jobs, conventions. Works with Claude Code, Cursor, GitHub Copilot, OpenCode and Codex CLI. MCP or CLI, in-Gemfile or standalone, and it still answers when the app can't boot.

Engineered for speed, consistency, and developer ease, it solves common hurdles in ai, ai-coding, claude. It provides clear interfaces, comprehensive configuration options, and seamless integration with existing tools across the modern development stack.

## Key Features
- Optimized execution pipeline written in Ruby for predictable speed.
- Zero-friction configuration with comprehensive sensible defaults out of the box.
- Cross-platform runtime support across Linux, macOS, and Windows environments.
- Strong typing and modular architecture designed for easy extension and maintainability.
- Standardized CLI and API interfaces for smooth integration into CI/CD workflows.
- Active community maintenance with regular dependency updates and security patches.

## Installation & Quick Start
### Linux
```bash
git clone https://github.com/crisnahine/rails-ai-context.git
cd rails-ai-context
```

### macOS
```bash
git clone https://github.com/crisnahine/rails-ai-context.git
cd rails-ai-context
```

### Windows
```bash
git clone https://github.com/crisnahine/rails-ai-context.git
cd rails-ai-context
```

## System Requirements & Architecture
- **Supported Platforms**: macOS, Linux, Windows
- **Runtime Dependencies**: Ruby >= 3.1 with Bundler
- **Architecture**: x86_64, ARM64 (Apple Silicon & Graviton)

## How It Works
rails-ai-context coordinates its core functionality through a modular Ruby pipeline. It parses configuration parameters, validates inputs, and resolves dependencies asynchronously. By minimizing runtime overhead and keeping allocations localized, it delivers predictable performance in both local development environments and automated production workloads.

## Production Use Cases
### Autonomous AI Agents
Orchestrate intelligent workflows and tool-calling routines with rails-ai-context.

### Model Inference & Prompting
Integrate fast, local or cloud-hosted generative AI models directly into production code.

### Context Memory & RAG
Augment language models with dynamic vector retrieval and structured project memory.

### Developer Productivity
Automate repetitive engineering tasks, code generation, and test creation using AI agents.

## Target Audience
Developers and engineering teams building with Ruby, seeking reliable, tested, and actively maintained tooling for production workloads.

## Strengths
- Active community backing with 159 GitHub stars and verified adoption.
- Permissive open-source distribution under the MIT license.
- Built in Ruby for high execution speed and developer familiarity.
- Cross-platform compatibility across modern Linux, macOS, and Windows environments.
- Clean modular design allowing flexible configuration and pipeline integration.

## Considerations
- Requires familiarity with Ruby and modern CLI workflows.
- Ecosystem extensions may require manual configuration depending on environment constraints.
- Active development roadmap means breaking API changes may occur across major versions.
