I Built a Directory of 600+ AI Addons — Here's Why

Zeph Wheeler — Thu, 12 Mar 2026 02:01:32 +0000

TL;DR: I created MCP Hub — a searchable directory of 602+ AI customization tools including MCP servers, Claude Skills, OpenClaw Skills, AI Personas, and OpenAI GPTs. Free to use, no signup required.

The Problem

If you use Claude, ChatGPT, or other AI assistants, you've probably wondered: "Can I extend this with custom tools?"

The answer is yes — but finding those tools is a mess:

MCP servers scattered across GitHub
Claude Skills buried in Discord servers
AI personas copy-pasted in Reddit threads
GPTs hidden in ChatGPT's search (if you can find them)

I spent hours hunting for good addons. So I built MCP Hub to solve this.

What is MCP Hub?

MCP Hub is a searchable directory of 602+ AI addons in one place:

359 MCP Servers — Tools for Claude Desktop (filesystem, GitHub, databases, APIs, etc.)
56 Claude Skills — Instruction sets for specialized workflows
65 OpenClaw Skills — Agent skills for OpenClaw platform
63 AI Personas — Expert character prompts for any AI
59 OpenAI GPTs — Custom ChatGPT bots

Each addon has:

Why I Built This

I'm a developer who uses AI tools daily. Setting up MCP servers for Claude was game-changing — suddenly I could:

Query my PostgreSQL database in natural language
Search my codebase without leaving the chat
Automate GitHub issues
Run shell commands safely

But finding good servers was painful. I'd spend 30+ minutes searching GitHub, Reddit, Discord just to discover one new tool.

MCP Hub was born from that frustration. I wanted one place to browse everything, compare options, and get instant setup instructions.
