Required User Actions

1. Enable Gmail API (Required for Email Checking)

Your Gmail MCP is configured but the Gmail API is not enabled on your Google Cloud project.

Steps: 1. Open: https://console.developers.google.com/apis/api/gmail.googleapis.com/overview?project=370216978185 2. Click "Enable" 3. Wait 2-5 minutes for propagation

After enabling, test with:

cd ~/.gmail-mcp && echo '{"jsonrpc": "2.0", "method": "tools/call", "params": {"name": "search_emails", "arguments": {"query": "is:unread", "maxResults": 1}}, "id": 1}' | npx -y @gongrzhe/server-gmail-autoauth-mcp

2. Install Docker (Required for Buzz)

curl -fsSL https://get.docker.com | sudo sh
sudo usermod -aG docker bryan
newgrp docker  # or log out and back in

Verify:

docker --version
docker compose version

3. Start Buzz Relay

Once Docker is installed:

cd ~/buzz/deploy/compose
cp .env.example .env
# Edit .env and set required values (especially secrets)
./run.sh start

For TLS with Let's Encrypt:

BUZZ_COMPOSE_TLS=true ./run.sh start

Hermes Gateway Configuration

Current Config (~/.hermes/config.yaml)

• Model: ornith:9b via Ollama (local)
• Memory: Enabled
• Gateway Service: Running (systemd)
• Gmail MCP: Enabled but needs API activation

Gateway Management

# Check status
hermes gateway status

# Restart gateway
sudo systemctl --user restart hermes-gateway

# View logs
journalctl --user -u hermes-gateway.service -f

Multi-Device Gateway Sync

Hermes gateway doesn't sync messages across devices, but provides continuity through:

1. Shared memory - Memory files persist on the gateway host
2. Named sessions - Use /title to name sessions, /resume to continue from any platform
3. Background tasks - /background for long-running tasks that persist results
4. Shared workspace - Artifacts land on gateway filesystem, accessible from any platform

To set up the same Hermes profile on MacBook Pro: 1. Copy ~/.hermes/.env and ~/.hermes/config.yaml 2. Run hermes setup on MacBook 3. Configure Gmail MCP with same OAuth credentials

Buzz Architecture

Buzz is a Nostr-based workspace where humans and AI agents collaborate.

Components: - Relay (Rust) - WebSocket + REST, Postgres, Redis - Desktop App (Tauri + React) - buzz-cli - Agent-first JSON CLI - Workflows - YAML automation triggers

Default Ports: - Relay WebSocket: ws://localhost:3000 - Postgres: 5432 - Redis: 6379 - MinIO (S3): 9000

Next Steps After Setup

1. [ ] Enable Gmail API
2. [ ] Install Docker
3. [ ] Start Buzz relay
4. [ ] Generate Nostr keypair for Buzz identity
5. [ ] Configure IBKR paper trading bot
