Features

• 🖥️ Droplet Management: Complete lifecycle management with resize and snapshot capabilities
• 💾 Volume Management: Block storage operations including attach/detach and snapshots
• 📸 Snapshot Operations: Backup and restore functionality for droplets and volumes
• 🖼️ Image Management: Custom image operations, transfers, and conversions
• 🌐 Floating IP Management: Static IP allocation, assignment, and management
• ⚖️ Load Balancer Operations: Traffic distribution with full CRUD operations
• 🔥 Firewall Management: Complete network security with rule and policy management
• ☸️ Kubernetes Operations: Comprehensive cluster and node pool management
• 📦 Container Registry: Access and manage DigitalOcean container registries
• ✅ Connection Testing: Verify API connectivity and authentication

Prerequisites

• Go 1.19 or higher
• DigitalOcean API token (required - see Configuration section)

Installation

From Source

git clone https://github.com/rohit-kaundal/digitalocean-mcp-server.git
cd digitalocean-mcp-server
go mod tidy
go build -o digitalocean-mcp-server

Using Go Install

go install github.com/rohit-kaundal/digitalocean-mcp-server@latest

Configuration

Environment Variables

REQUIRED: Set your DigitalOcean API token before running the server:

export DIGITALOCEAN_ACCESS_TOKEN="your_digitalocean_api_token"

⚠️ The server will not function without this environment variable set.

Getting a DigitalOcean API Token

1. Log in to your DigitalOcean Control Panel
2. Navigate to API in the left sidebar
3. Click Generate New Token
4. Give your token a name and select appropriate scopes
5. Copy the generated token (you won't be able to see it again)

Usage

Running the Server

First, ensure your DigitalOcean API token is set:

export DIGITALOCEAN_ACCESS_TOKEN="your_digitalocean_api_token"

Then run the server:

./digitalocean-mcp-server

Or run directly with Go:

go run main.go

The server will start and listen for MCP requests via stdio transport.

Development Commands

# Run the server
go run main.go

# Run tests
go test ./...

# Build binary
go build -o digitalocean-mcp-server

# Update dependencies
go mod tidy

Adding New Tools

1. Define argument types in types/args.go
2. Implement handler logic in the appropriate file under handlers/
3. Register the tool in server/tools.go
4. Update this documentation

Dependencies

• godo - DigitalOcean API client
• mcp-golang - MCP protocol implementation
• oauth2 - OAuth2 authentication

Error Handling

All tools return standardized MCP responses:

• Success: JSON-formatted data with the requested information
• Error: Structured error messages with details about what went wrong

Common error scenarios:

• Invalid or missing API token
• Insufficient permissions
• Resource not found
• API rate limiting
• Network connectivity issues
