GitHub Agent - A2A | AG-UI | MCP

Version: 0.1.1

Overview

GitHub Agent is a powerful Model Context Protocol (MCP) server and Agent-to-Agent (A2A) system designed to interact with GitHub.

It acts as a Supervisor Agent, delegating tasks to a suite of specialized Child Agents, each focused on a specific domain of the GitHub API (e.g., Issues, Pull Requests, Repositories, Actions). This architecture allows for precise and efficient handling of complex GitHub operations.

This repository is actively maintained - Contributions are welcome!

Capabilities:

• Supervisor-Worker Architecture: Orchestrates specialized agents for optimal task execution.
• Comprehensive GitHub Coverage: specialized agents for Issues, PRs, Repos, Actions, Organizations, and more.
• MCP Support: Fully compatible with the Model Context Protocol.
• A2A Integration: Ready for Agent-to-Agent communication.
• Flexible Deployment: Run via Docker, Docker Compose, or locally.

Usage

Prerequisites

• Python 3.10+
• A valid GitHub Personal Access Token (PAT) with appropriate permissions.

Installation

pip install github-agent

Or using UV:

uv pip install github-agent

CLI

The github-agent command starts the server.

Argument	Description	Default
--host	Host to bind the server to	0.0.0.0
--port	Port to bind the server to	9000
--mcp-config	Path to MCP configuration file	mcp_config.json
--provider	LLM Provider (openai, anthropic, google, etc.)	openai
--model-id	LLM Model ID	qwen/qwen3-4b-2507

Running the Agent Server

github-agent --provider openai --model-id gpt-4o --api-key sk-...

Docker

Build

docker build -t github-agent .

Run using Docker

docker run -d \
  -p 9000:9000 \
  -e OPENAI_API_KEY=sk-... \
  -e MCP_CONFIG=/app/mcp_config.json \
  knucklessg1/github-agent:latest

Run using Docker Compose

Create a docker-compose.yml:

services:
  github-agent:
    image: knucklessg1/github-agent:latest
    ports:
      - "9000:9000"
    environment:
      - PROVIDER=openai
      - MODEL_ID=gpt-4o
      - OPENAI_API_KEY=${OPENAI_API_KEY}
    volumes:
      - ./mcp_config.json:/app/mcp_config.json

Then run:

docker-compose up -d
