| 17 | # OpenSkills: Run Claude Skills Locally on Your Mac |
| 18 | |
| 19 | Anthropic recently announced [Skills for Claude](https://www.anthropic.com/news/skills) - reusable folders with instructions, scripts, and resources that make Claude better at specialized tasks. This tool lets you run these skills **entirely on your local machine** in a sandboxed environment. |
| 20 | |
| 21 | **What this means:** You can now process your files (documents, spreadsheets, presentations, images) using these specialized skills while keeping all data on your Mac. No uploads, complete privacy. |
| 22 | |
| 23 | > This tool executes AI-generated code in a truly isolated sandboxed environment on your Mac using Apple's native containers. |
| 24 | |
| 25 | ## Demo |
| 26 | |
| 27 | Watch Open-Skills in action with Gemini CLI: |
| 28 | |
| 29 |  |
| 30 | |
| 31 | ## Why Run Skills Locally? |
| 32 | |
| 33 | - **Privacy:** Process sensitive documents, financial data |
| 34 | - **Full Control:** Skills execute in an isolated container with VM-level isolation |
| 35 | - **Compatibility:** Works with Claude Desktop, Gemini CLI, Qwen CLI, or any MCP-compatible tool |
| 36 | - **Extensibility:** Import Anthropic's official skills or create your own custom skills |
| 37 | |
| 38 | ## Quick Start |
| 39 | |
| 40 | **Prerequisites:** Mac with macOS and Apple Silicon (M1/M2/M3/M4/M5), Python 3.10+ |
| 41 | |
| 42 | ```bash |
| 43 | git clone https://github.com/BandarLabs/open-skills.git |
| 44 | cd open-skills |
| 45 | chmod +x install.sh |
| 46 | ./install.sh |
| 47 | ``` |
| 48 | |
| 49 | Installation takes ~2 minutes. The MCP server will be available at `http://open-skills.local:8222/mcp` |
| 50 | |
| 51 | **Install required packages** (use virtualenv and note the python path): |
| 52 | ```bash |
| 53 | pip install -r examples/requirements.txt |
| 54 | ``` |
| 55 | |
| 56 | ## Setup: Connect Your AI Tool |
| 57 | |
| 58 | This MCP server works with any MCP-compatible tool. All execution happens locally on your Mac. |
| 59 | |
| 60 | ### Option 1: Claude Desktop Integration |
| 61 | |
| 62 | Configure Claude Desktop to use this MCP server: |
| 63 | |
| 64 | 1. **Copy the example configuration:** |
| 65 | ```bash |
| 66 | cd examples |
| 67 | cp claude_desktop/claude_desktop_config.example.json claude_desktop/claude_desktop_config.json |
| 68 | ``` |
| 69 | |
| 70 | 2. **Edit the configuration file** and replace the placeholder paths: |
| 71 | - Replace `/path/to/your/python` with your actual Python path (e.g., `/usr/bin/python3` or `/opt/homebrew/bin/python3`) |
| 72 | - Replace `/path/to/open-skills` with the actual path to your cloned repository |
| 73 | |
| 74 | Example after editing: |
| 75 | ```json |
| 76 | { |
| 77 | "mcpServers": { |
| 78 | "open-skills": { |
| 79 | "command": "/opt/homebrew/bin/python3", |
| 80 | "args": ["/Users/yourname/open-skills/examples/claude_desktop/mcpproxy.py"] |
| 81 | } |
| 82 | } |
| 83 | } |
| 84 | ``` |
| 85 | |
| 86 | 3. **Update Claude Desktop configuration:** |
| 87 | - Open Claude Desktop |
| 88 | - Go to Settings → Developer |
| 89 | - Add the MCP server configuration |
| 90 | - Restart Claude Desktop |
| 91 | |
| 92 | ### Option 2: OpenCode Configuration |
| 93 | |
| 94 | For OpenCode users, create `~/.config/opencode/opencode.json`: |
| 95 | |
| 96 |  |
| 97 | |
| 98 | ```json |
| 99 | { |
| 100 | "$schema": "https://opencode.ai/config.json", |
| 101 | "mcp": { |
| 102 | "open-skills": { |
| 103 | "type": "remote", |
| 104 | "url": "http://open-skills.local:8222/mcp", |
| 105 | "enabled": true |
| 106 | } |
| 107 | } |
| 108 | } |
| 109 | ``` |
| 110 | |
| 111 | ### Option 3: Gemini CLI Configuration |
| 112 | |
| 113 | Edit `~/.gemini/settings.json`: |
| 114 | |
| 115 | ```json |
| 116 | { |
| 117 | "theme": "Default", |
| 118 | "selectedAuthType": "oauth-personal", |
| 119 | "mcpServers": { |
| 120 | "open-skills": { |
| 121 | "httpUrl": "http://open-skills.local:8222/mcp" |
| 122 | } |
| 123 | } |
| 124 | } |
| 125 | ``` |
| 126 | |
| 127 | For system instructions, replace `~/.gemini/GEM |
