# Implementation Summary: Claude Code Configuration
## Overview
Successfully implemented Claude Code CLI support for the Garmin Health MCP Server, enabling seamless access to Garmin health data from both Claude Code and Claude Desktop.
## Changes Made
### 1. ✅ Fixed Token Storage Path (Phase 1)
**File**: `scripts/garmin_auth.py` (line 21)
**Change**:
```python
# OLD (Clawdbot-specific)
TOKEN_DIR = Path.home() / ".clawdbot" / "garmin"
# NEW (MCP server local)
TOKEN_DIR = Path(__file__).parent.parent / ".garmin-tokens"
```
**Impact**: Removes dependency on Clawdbot directory structure. Tokens now stored locally in `.garmin-tokens/` within the MCP server directory, making the setup self-contained.
### 2. ✅ Updated .gitignore (Phase 1)
**File**: `.gitignore`
**Added**:
```
.garmin-tokens/
```
**Impact**: Prevents accidentally committing authentication tokens to git.
### 3. ✅ Created .mcp.json Configuration (Phase 2)
**File**: `.mcp.json` (new)
**Content**:
```json
{
"mcpServers": {
"garmin-health": {
"type": "stdio",
"command": "node",
"args": ["D:\\garmin-health-mcp-server\\index.js"],
"env": {
"GARMIN_EMAIL": "${GARMIN_EMAIL}",
"GARMIN_PASSWORD": "${GARMIN_PASSWORD}"
}
}
}
}
```
**Impact**: Enables automatic MCP server loading in Claude Code. Uses environment variable expansion for security.
### 4. ✅ Created Claude Code Setup Guide (Phase 7)
**File**: `CLAUDE_CODE_SETUP.md` (new)
**Contents**:
- Quick setup instructions (5 minutes)
- Environment variable configuration for Windows/Linux/macOS
- Authentication steps
- Testing and verification procedures
- Comprehensive troubleshooting guide
- Example usage queries
- Advanced configuration options
**Impact**: Provides complete, standalone guide for Claude Code users.
### 5. ✅ Updated README.md (Phase 7)
**Changes**:
- Updated tagline to mention Claude Code CLI
- Added prerequisites for Claude Code
- Added new section: "Using with Claude Code CLI"
- Linked to detailed CLAUDE_CODE_SETUP.md guide
- Quick start instructions for Claude Code users
**Impact**: Main README now covers both Claude Desktop and Claude Code usage.
### 6. ✅ Updated INSTALL.md (Phase 7)
**Changes**:
- Added 🟣 Claude Code CLI as installation option #1 (recommended)
- Reordered existing options (Claude Desktop now #2, Clawdbot now #3)
- Added quick install instructions for Claude Code
- Updated "Using Multiple Installations" section
- Added note about shared authentication tokens
**Impact**: Installation guide now presents Claude Code as the recommended starting point.
## Architecture Overview
### Token Storage
- **Location**: `.garmin-tokens/` (local to MCP server directory)
- **Shared**: Same tokens used by Claude Code, Claude Desktop, and Clawdbot
- **Security**: Directory permissions set to 0o700, excluded from git
### Environment Variables
- **Required**: `GARMIN_EMAIL`, `GARMIN_PASSWORD`
- **Configuration**: System/user environment variables (not .env files for MCP)
- **Security**: Environment variable expansion in .mcp.json prevents hardcoding credentials
### MCP Server
- **Entry Point**: `index.js` (unchanged, already compatible)
- **Transport**: stdio (works with both Claude Code and Claude Desktop)
- **Backend**: Python scripts in `scripts/` directory
- **Authentication**: `scripts/garmin_auth.py` handles login and token management
## Testing Checklist
### ✅ Code Changes Verified
- [x] `scripts/garmin_auth.py` line 21 updated to use local token directory
- [x] `.gitignore` includes `.garmin-tokens/`
- [x] `.mcp.json` created with correct configuration
- [x] Documentation files created and updated
### 🔲 Next Steps for User Testing
Before the server can be used, the user needs to:
1. **Set environment variables**:
```powershell
# Windows
setx GARMIN_EMAIL "your-email@example.com"
setx GARMIN_PASSWORD "your-password"
```
2. **Restart terminal** to load new environment variables
3. **Run authentication**:
```bash
npm run auth
```
4. **Test in Claude Code**:
```bash
claude
/mcp # Should show garmin-health server
```
5. **Test queries**:
- "How did I sleep last night?"
- "What's my body battery today?"
## Compatibility
### Claude Code CLI
- ✅ Configured via `.mcp.json`
- ✅ Uses environment variable expansion
- ✅ Auto-loads when `claude` command is run
- ✅ Shares tokens with other installations
### Claude Desktop
- ✅ No changes to existing configuration
- ✅ Continues working via `claude_desktop_config.json`
- ✅ Shares tokens with other installations
### Clawdbot (if installed)
- ⚠️ Requires manual token directory migration
- ⚠️ Update Clawdbot config to point to new `.garmin-tokens/` directory
- ✅ Can share tokens after migration
## Key Benefits
1. **Self-Contained Setup**: No dependency on external directory structures
2. **Secure by Default**: Environment variable expansion prevents credential exposure
3. **Shareable Configuration**: `.mcp.json` can be committed to git safely
4. **Multi-Interface Support**: Works with Claude Code, Claude Desktop, and Clawdbot
5. **Simple Authentication**: Single `npm run auth` command for all interfaces
## Potential Issues & Solutions
### Issue 1: Environment Variables Not Set
**Symptom**: "GARMIN_EMAIL and GARMIN_PASSWORD environment variables not set"
**Solution**: Set system environment variables and restart terminal
### Issue 2: Path in .mcp.json Incorrect
**Symptom**: MCP server fails to load in Claude Code
**Solution**: Update `args` path in `.mcp.json` to match actual installation directory
### Issue 3: Python Not Found
**Symptom**: "python3: command not found"
**Solution**: Add Python to system PATH or use full Python path in scripts
### Issue 4: Existing Clawdbot Tokens
**Symptom**: Tokens still in `~/.clawdbot/garmin/` but not found by new code
**Solution**: Run `npm run auth` to create new tokens in `.garmin-tokens/`
