## 📖 About This Series
The **Enterprise MCP Series** is an **open-source initiative** designed to help you **build** modular, **production-grade AI automation systems** using the **Model Context Protocol (MCP)**.
In this series, we focus on building a **Pull Request Reviewer** for an enterprise project, showcasing how to integrate multiple tools and orchestrate them into a scalable, production-ready MCP architecture.
### 🎯 Why This Series?
Unlike simple tutorials, this series tackles **real-world, enterprise use cases**—like a **Pull Request Reviewer Assistant** that analyzes GitHub PRs, pulls context from Github and Asana, and posts actionable insights to your team on Slack.
It shows how to:
- **Automate AI workflows** within your internal systems
- **Build scalable infrastructure** – design workflows that support multiple automation pipelines, ready to grow with your organization
- **Evaluate MCP for enterprise migration** – understand if migrating your codebase to an MCP-based architecture is worth it
### 🛠 What You Will Learn
You will learn how to:
- **Build custom MCP Servers** for Slack and Asana to expose enterprise tools and resources
- **Connect to external MCP servers** (e.g., GitHub Remote MCP) and integrate them seamlessly
- **Centralize tools and prompts** into an internal **Tool Registry** (a global MCP server)
- **Create a custom MCP Host** to orchestrate workflows (no reliance on Claude Desktop)
- **Design and scale company-wide automation workflows**, starting with the PR Reviewer use case
With these skills, you'll become a pro 🥷 at building enterprise-ready AI automation systems using MCP, designing your own scalable hosts, integrating internal tools, and orchestrating intelligent workflows across your company.
