## 🔐 Next Steps: OAuth Setup Required
The Gmail server is deployed but **NOT YET FUNCTIONAL** because OAuth credentials need to be configured:
### Step 1: Google Cloud Console Setup
1. Go to [Google Cloud Console](https://console.cloud.google.com/)
2. Create/select project
3. Enable Gmail API
4. Create OAuth 2.0 Client ID (Desktop app)
5. Download `credentials.json`
### Step 2: Initial OAuth Flow
```bash
cd ~/.claude/mcp-servers/gmail-mcp
source .venv/bin/activate
python oauth_setup.py
```
This will:
- Open browser for Google OAuth consent
- Request gmail.modify scope
- Display client_id, client_secret, and refresh_token
### Step 3: Store in OpenBao
```bash
# Ensure OpenBao agent is running
start-openbao-mcp
# Store credentials (replace with actual values from oauth_setup.py)
bao kv put secret/client0/prod-mcp-gmail-samuel \
client_id="YOUR_CLIENT_ID.apps.googleusercontent.com" \
client_secret="YOUR_CLIENT_SECRET" \
refresh_token="YOUR_REFRESH_TOKEN"
```
### Step 4: Regenerate Hierarchy
After storing credentials:
```bash
cd ~/.claude/mcp-proxy
./structure_generator --config config.json --output hierarchy/
```
This will add Gmail tools to the hierarchy.
### Step 5: Restart Claude Code
Restart Claude Code to load the Gmail server with mcp-proxy.
## 🧪 Testing
After OAuth setup, test the server:
```bash
# Test server startup
cd ~/.claude/mcp-servers/gmail-mcp
source .venv/bin/activate
python gmail_mcp.py
# Should print "MCP_SERVER_READY" to stderr
# Test with MCP Inspector
npx @modelcontextprotocol/inspector \
~/.claude/mcp-servers/gmail-mcp/.venv/bin/python \
~/.claude/mcp-servers/gmail-mcp/gmail_mcp.py
```
## 📚 Documentation
- **README.md**: Complete setup and usage guide
- **EVALUATIONS.md**: Testing guide (requires test account)
- **DEPLOYMENT.md**: This file
## 🎯 OAuth Scope
The server requires:
- `https://www.googleapis.com/auth/gmail.modify` (full mailbox access)
## 🚨 Current Status
- ✅ Server implementation complete
- ✅ Installed to `.claude/mcp-servers/gmail-mcp/`
- ✅ Added to mcp-proxy config
- ✅ Dependencies installed
- ⚠️ **OAuth credentials NOT configured** (next step required)
- ⚠️ **Hierarchy files NOT generated** (will generate after OAuth setup)
- ⏸️ Server cannot start until OAuth credentials are in OpenBao
## 🔄 Development Mode (Alternative)
For testing without OpenBao:
```bash
export OPENBAO_DEV_MODE=1
export GMAIL_CLIENT_ID="your-client-id"
export GMAIL_CLIENT_SECRET="your-client-secret"
export GMAIL_REFRESH_TOKEN="your-refresh-token"
cd ~/.claude/mcp-servers/gmail-mcp
source .venv/bin/activate
python gmail_mcp.py
```
## 📦 Repository Cleanup
The development repository at `~/repos/3-resources/MCP/gmail-mcp/` is a separate git repository for tracking changes and development. The installed server at `~/.claude/mcp-servers/gmail-mcp/` is independent and will continue to work.
## 🎉 Summary
**Gmail MCP Server v1.0** is ready for activation after OAuth setup!
- Implementation: ✅ Complete (17 tools)
- Installation: ✅ Complete
- Configuration: ✅ Complete
- OAuth Setup: ⏳ Pending (follow steps above)
- Hierarchy Generation: ⏳ Pending (after OAuth)
- Ready to Use: ⏸️ After OAuth setup
