How do I use DuploCloud Docker MCP Server?

1. Click on "Install Server". 2. Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state. 3. In the chat, type @ followed by the MCP server name and your instructions, e.g., "@DuploCloud Docker MCP Server list all services in the 'production' tenant" That's it! The server will respond to your query, and you can continue using it as needed. Here is a step-by-step guide with screenshots.

Troubleshooting

Missing environment variables

DuploError: DUPLO_HOST environment variable is required

Set DUPLO_HOST and DUPLO_TOKEN before running. See .env.example.

Invalid or expired token

{"error": "Unauthorized", "code": 401}

Generate a new API token from the DuploCloud portal: User menu > Security > API Token.

Tenant not found

{"error": "Tenant 'xyz' not found", "code": 404}

Verify the tenant name with tenant_list. Tenant names are case-sensitive.

Connection refused

{"error": "Unexpected error: Connection refused", "code": 500}

Verify DUPLO_HOST is correct and the DuploCloud portal is reachable from your network.

Architecture

main.py                          # Entrypoint: mcp.run(transport="stdio")
duplocloud_mcp/
  server.py                      # FastMCP instance, imports tool modules
  client.py                      # DuploClient singleton wrapper
  errors.py                      # Error decorator, validators
  tools/
    tenants.py                   # Tenant CRUD tools
    services.py                  # Service CRUD + restart tools
    hosts.py                     # Host CRUD + reboot tools
    databases.py                 # RDS database CRUD tools
    storage.py                   # S3 bucket CRUD tools
    containers.py                # ECS service/task tools

Each tool module imports the shared mcp instance from server.py and registers tools via @mcp.tool(). The @handle_duplo_errors decorator translates DuploCloud exceptions into structured JSON error responses. The duplocloud-client library handles all REST API communication.
