Arclio Rules 🚀

Arclio Rules is a FastAPI-based service that implements rule processing using the FastMCP framework. It provides a robust and efficient system for managing and executing business rules in a microservices architecture.

Overview

Arclio Rules is built with Python 3.12+ and leverages modern async capabilities to provide high-performance rule processing. The service can be run either with session management or in a stateless mode using standard I/O.

Features

• FastAPI-based REST API
• Built on FastMCP framework for efficient rule processing
• Redis integration for rule indexing/storage and querying
• Git integration for version control of rules
• Support for both session-based and stateless operation modes
• Frontmatter parsing capabilities
• Comprehensive logging with Loguru
• UV package management for fast, reliable dependency handling
• Make-based workflow automation

Prerequisites

• Python 3.12.8 or higher
• UV package manager
• Docker (optional, for containerized deployment)
• Age (for secrets management)

Installation

1. Clone the repository:

git clone https://github.com/fisseha-estifanos/arclio-rules.git
cd arclio-rules

2. Install dependencies using UV:

make install

This will:

• Install project dependencies using UV
• Set up the development environment
• Sync all dependencies

Environment Setup

1. Initialize SOPS for secret management:

make init-key

2. Create your environment file:

# Copy the example environment file
cp .env.example .env

# Decrypt existing secrets (if you have access)
make decrypt

Required Environment Variables:

# GitHub API Configuration
GITHUB_TOKEN="add your GH PAT here"
GITHUB_ORG="add your GH Organization here"
REPO_NAME="add your repo that holds the rules here"
REDIS_HOST="localhost"
REDIS_PORT="6379"
REDIS_PASSWORD="add your password here if there is one"

Default Environmental Variables (No need to modify):

# Server Configuration
PORT=8000                     # Application port
HOST=0.0.0.0                  # Host to bind to

# Additional Settings
LOG_LEVEL=INFO                # Logging level (DEBUG, INFO, WARNING, ERROR)
ENVIRONMENT=development       # Application environment

Usage

The service can be run in two modes:

Stateless Mode (using stdio)

source .env
arclio-rules

Development Mode

make run-dev

Adding mcp-server on Arclio

Add these two configuration JSON templates to be able to add arclio-rules to Arclio as an mcp-server.
