AI Addon Stack: MCP + Skills + Personas Together
Power users don't choose one addon type — they build a stack. This guide shows you exactly how to combine MCP Servers, Claude Skills, OpenClaw Skills, and AI Personas into a unified, powerful AI environment.
What is an AI Addon Stack?
An AI addon stack is your personal combination of AI extensions working together. Just like a tech stack (React + Node + PostgreSQL), your AI stack layers different addon types for a complete solution.
At MCP Hub, we host 264 addons across all four types. Here's how to pick the right ones and make them work together.
The Universal Starter Stack
Regardless of your role, this stack gives you a solid foundation:
- MCP Server: Brave Search — Web research without leaving your AI chat
- Claude Skill: Word Document Creation — Professional document output
- AI Persona: Pick one matching your profession
This costs nothing extra, takes 10 minutes to set up, and immediately improves your AI experience.

Setting Up Your Stack
Step 1: Install MCP Servers
Follow our MCP installation guide. Most servers install with one command:
npx @anthropic/create-mcp-server filesystemStep 2: Add Claude Skills
In Claude, create a Project and add skill instructions to the system prompt. You can have multiple skills per Project.
Step 3: Apply Your Persona
Add persona instructions to the same Project's system prompt, after your skills. The persona shapes how Claude uses the skills.
Step 4: Set Up OpenClaw (Optional)
Follow our OpenClaw setup guide for autonomous agent capabilities.
Optimization Tips
- Don't overload: 5-8 MCP servers is the sweet spot. More adds startup time without proportional benefit.
- Use the right model: Complex workflows benefit from Claude Opus. Simple tasks work great with Haiku.
- Separate projects: Create different Claude Projects for different workflows (coding project, writing project, analysis project).
- Monitor resource usage: MCP servers use RAM. Close servers you're not actively using.
Troubleshooting Multi-Addon Setups
MCP server conflicts
If two servers provide similar tools, the AI may get confused. Solution: give each server a clear, distinct purpose.
Persona overriding skill behavior
If the persona's communication style conflicts with a skill's output format, put the skill instructions first in your system prompt, then the persona. Skills take precedence for output format; persona shapes the content.
Slow startup
Many MCP servers = slow initial load. Only install servers you use regularly. Use our troubleshooting guide for specific issues.
