Kairos Codex - MCP Server

This server implements the Model Context Protocol (MCP) to provide standardized access to Bible data resources. It acts as a "tool provider" for Large Language Models (LLMs), allowing them to query Bible translations, books, and verses.

• get_books - Get list of books available in a specific Bible translation
• get_verses - Get specific verse(s) from a chapter in a given translation
• get_chapter - Get an entire chapter from a book in a given translation

Getting Started

Prerequisites

• Python 3.11+
• Required packages: fastmcp, httpx, pydantic, PyYAML, python-dotenv

Installation

Install dependencies:

pip install -r requirements.txt

Configuration

Optionally set authentication token for access control. You can do this in two ways:

Option 1: Environment variable

export BIBLE_SERVER_TOKEN=your_token_here

Option 2: .env file (recommended)

Create a .env file in the project root:

echo "BIBLE_SERVER_TOKEN=your_token_here" > .env

If no token is set, the server runs without authentication.

Running the Server

Direct Python execution:

python bible.py

Using Docker:

# Build and run with docker-compose
docker-compose up --build

# Or build and run manually
docker build -t kairos-codex-mcp .
docker run -p 8000:8000 kairos-codex-mcp

The server runs using streamable HTTP transport on port 8000 and can be connected to by MCP clients.
