Connect your AI assistant to Obsidian! This Model Context Protocol (MCP) server enables Claude, Cursor, and other AI tools to read, write, search, and manage your Obsidian notes through the Local REST API.

## 🚀 Quick Setup

### 1. Install Obsidian Plugin

1. **Install "Local REST API"** from Community Plugins in Obsidian
2. **Set an API key** in plugin settings
3. **Start the server** using Command Palette: "Local REST API: Start"
4. **Note the URL**: `http://127.0.0.1:27123` (default)

### 2. Install ObsidianMCPServer

**Option A: Install from source code directly**

```bash
git clone https://github.com/otaviocc/ObsidianMCPServer.git
cd ObsidianMCPServer
swift build -c release

# The executable will be at: .build/release/ObsidianMCPServer
```

**Option B: Install via [Brew](https://brew.sh) 🤩**

```bash
brew tap otaviocc/mcp
brew install obsidian-mcp-server

# The executable will be at: `/opt/homebrew/bin/obsidian-mcp-server`
```

**Option C: Install via [Mint](https://github.com/yonaskolb/Mint)**

```bash
mint install otaviocc/ObsidianMCPServer

# The executable will be at: `$HOME/.mint/bin/ObsidianMCPServer`
```

### 3. Configure Your AI Tool

**Claude Desktop** (`~/Library/Application Support/Claude/claude_desktop_config.json`):
```json
{
  "mcpServers": {
    "obsidian": {
      "command": "/path/to/ObsidianMCPServer",
      "env": {
        "OBSIDIAN_BASE_URL": "http://127.0.0.1:27123",
        "OBSIDIAN_API_KEY": "your-api-key-here"
      }
    }
  }
}
```

**Cursor**: Add the same configuration in Settings → Tools & Integration

Replace `/path/to/ObsidianMCPServer` with your actual path:
- **Source build**: `.build/release/ObsidianMCPServer` (from your build directory)
- **Brew install**: `/opt/homebrew/bin/obsidian-mcp-server`
- **Mint install**: `$HOME/.mint/bin/ObsidianMCPServer`

Also replace `your-api-key-here` with your plugin's API key.

## 🔧 Requirements

- **macOS 12.0+** with **Swift 6.0+**
- **Obsidian** with **Local REST API plugin**

## 🔒 Security

- API key stays local (never transmitted to external services)
- Server runs on localhost only
- Enable HTTPS in plugin for encrypted communication (port 27124)
- Only use with trusted AI applications

## 🐛 Troubleshooting

**Connection Issues:**
- Verify Obsidian Local REST API plugin is running
- Check base URL matches plugin settings (27123 for HTTP, 27124 for HTTPS)
- Confirm API key matches plugin configuration

**Build Issues:**
- Ensure Swift 6.0+ is installed
- Try `swift package clean` and rebuild
