Vento Remote MCP is a production-ready remote server that bridges Claude (claude.ai, mobile app, Claude Desktop, Claude Code, and the Anthropic API) with any Vento instance (self-hosted or cloud.vento.build). It enables AI assistants to read sensor values, monitor device status, and execute real-world actions through Vento boards and agents.

What is Vento?

Vento is an AI control and automation platform for devices, machines, and spaces:

• Boards: Visual dashboards composed of cards representing sensors (value cards) and actuators (action cards)
• AI Agents: LLM-powered decision loops that observe the world, make decisions, and take action
• Device Integration: Native support for ESP32/ESPHome, Android phones, Go/Python agents, and custom MQTT devices
• Real-time Control: MQTT-based instant communication with physical devices and sensors

Railway

Render

Fly.io

fly launch --repo https://github.com/geromendez199/vento-remote-mcp
fly secrets set MCP_AUTH_TOKEN=your-token
fly secrets set VENTO_API_URL=https://your-vento-instance.com
fly secrets set VENTO_TOKEN=your-vento-api-token
fly deploy

VPS + Cloudflared

# Deploy to VPS
git clone https://github.com/geromendez199/vento-remote-mcp.git
cd vento-remote-mcp
npm install && npm run build

# Install systemd service
sudo cp systemd/vento-remote-mcp.service /etc/systemd/system/
sudo systemctl enable vento-remote-mcp
sudo systemctl start vento-remote-mcp

# Expose via Cloudflared tunnel
cloudflared tunnel create vento-mcp
cloudflared tunnel route dns vento-mcp your-domain.com
cloudflared tunnel run --token $TUNNEL_TOKEN

Configuration

Create .env file:

# Server
PORT=3000
LOG_LEVEL=info

# Security
MCP_AUTH_TOKEN=<generate with: openssl rand -hex 32>

# Vento Connection
VENTO_API_URL=http://localhost:8000
VENTO_TOKEN=your-vento-api-token

# Rate Limiting
RATE_LIMIT_ENABLED=true
RATE_LIMIT_REQUESTS_PER_MINUTE=60

Using with Claude

Claude.ai or Claude Mobile App

1. Go to claude.ai/app
2. Click Settings → Custom Connectors
3. Click Add Custom Connector
4. Enter:
   • Name: Vento
   • Server URL: https://your-connector-url.com (public URL of your deployment)
5. In the request header section, add:
   • Key: Authorization
   • Value: Bearer YOUR_MCP_AUTH_TOKEN
6. Save

Now you can ask Claude to "list my Vento boards" or "turn on the pump".

Claude Desktop

Add to ~/.claude/mcp.json:

{
  "mcpServers": {
    "vento": {
      "url": "https://your-connector-url.com",
      "auth": {
        "type": "bearer",
        "token": "YOUR_MCP_AUTH_TOKEN"
      }
    }
  }
}

Claude Code

claude mcp add --transport http vento https://your-connector-url.com \
  --header "Authorization: Bearer YOUR_MCP_AUTH_TOKEN"

Cursor

Add to ~/.cursor/mcp.json:

{
  "mcpServers": {
    "vento": {
      "url": "https://your-connector-url.com",
      "auth": {
        "type": "bearer",
        "token": "YOUR_MCP_AUTH_TOKEN"
      }
    }
  }
}

Available Tools

All tools are read-only unless noted otherwise.

Tool	Description	Use Case
vento_list_boards	List all boards with name and description	Discover available boards
vento_get_board	Get complete board state: cards and current values	Monitor sensor data and see available actions
vento_get_card_value	Get current value of a specific sensor card	Check single sensor reading
vento_list_devices	List connected devices (ESP32, Android, etc.)	Monitor device network status
vento_run_action	Execute an action card ⚠️	Control pumps, motors, GPIO, send alerts
vento_send_to_agent	Send message to Vento AI agent	Trigger automation flows using natural language

Every tool accepts an optional instance argument to target a specific Vento instance when VENTO_INSTANCES is configured (see below).

Production Features

Tool permissions (read-only mode)

# Allowlist specific tools (unset = all)
ALLOWED_TOOLS=vento_list_boards,vento_get_board,vento_get_card_value

# Or just hide destructive tools (vento_run_action)
ALLOW_DESTRUCTIVE_TOOLS=false

Blocked tools are removed from discovery and rejected at execution — a client that skips tools/list still can't call them.

Multiple Vento instances

VENTO_INSTANCES={"staging":{"url":"https://staging.vento.example.com","token":"tok"}}

The primary instance (VENTO_API_URL) is always available as default. Claude can then say: "compare the temperature on production and staging" — each tool call routes via its instance argument.

Observability

Endpoint	Purpose
GET /health	Readiness: pings Vento, reports latencyMs (503 when degraded)
GET /health/live	Liveness: cheap, no upstream calls
GET /metrics	Prometheus metrics (bearer-auth protected)
GET /info	Server version, instances, exposed tools with danger levels

Metrics include request duration histograms, Vento API call counters, per-tool execution counters, auth failures, rate-limited requests, and cache hit/miss. Every HTTP response carries an X-Request-Id that appears in all correlated log lines.

Rate limiting & caching

• Per-token rate limiting: RATE_LIMIT_REQUESTS_PER_MINUTE (default 60) plus RATE_LIMIT_BURST_PER_SECOND (default 10). Clients are keyed by token hash.
• Board reads are cached for CACHE_TTL_SECONDS (default 30) and invalidated automatically when an action executes on that board. Live sensor reads are never cached.

Security

⚠️ Important: This connector controls real physical devices. Use with caution.

Authentication

1. Claude ↔ Connector: Bearer token in HTTP headers

   • Set MCP_AUTH_TOKEN to a strong random value (min 32 characters)
   • Generate: openssl rand -hex 32
   • Never commit tokens to version control

2. Connector ↔ Vento: API token in environment variables

   • Store VENTO_TOKEN in environment, not in code
   • Use separate tokens for dev/prod
   • Rotate regularly

Permissions

• Use ALLOW_DESTRUCTIVE_TOOLS=false for read-only deployments
• Use ALLOWED_TOOLS to expose only specific tools
• Bearer comparison is timing-safe; auth failures are counted in /metrics
• Rate limiting is on by default (per-token, with burst control)

Best Practices

✅ DO:

• Use strong, randomly generated tokens
• Rotate tokens regularly
• Deploy over HTTPS only
• Monitor logs for suspicious activity
• Restrict Vento board access to essential actions
• Test actions in development first

❌ DON'T:

• Commit tokens to git
• Use the same token across multiple deployments
• Expose the connector to untrusted networks
• Disable authentication
• Connect to production Vento with test credentials

Troubleshooting

"Invalid authorization header"

Make sure you're using Bearer token authentication:

Authorization: Bearer YOUR_MCP_AUTH_TOKEN

"Failed to connect to Vento API"

Check:

1. VENTO_API_URL is correct and accessible
2. VENTO_TOKEN is valid
3. Firewall allows outbound connections
4. Vento instance is running and healthy

Connector not showing in Claude

1. Verify the public URL is accessible: curl https://your-url.com/health
2. Check token is correct in Claude settings
3. Wait 1-2 minutes for Claude to sync
4. Restart Claude app if needed

Actions not executing

1. Test directly with curl:

   curl -X POST https://your-url.com/mcp \
     -H "Authorization: Bearer YOUR_TOKEN" \
     -H "Content-Type: application/json" \
     -d '{"method":"initialize","params":{}}'
   

2. Check Vento board exists and action is enabled
3. Review logs: docker compose logs connector
