How to Set Up and Use Domain Availability
The DigitalOcean Remote MCP Server Template is a Python-based MCP server that checks domain name availability using both WHOIS lookups and DNS resolution, designed to be deployed as a remote HTTP MCP endpoint on DigitalOcean App Platform. It supports batch checking of multiple domains concurrently with async operations and timeout handling, and is intended both as a production-ready domain availability tool and as a reference template for building and deploying your own remote MCP servers to DigitalOcean. Developers and startup founders use it to quickly validate domain ideas from within Claude or another MCP client.
Prerequisites
- Python 3.9 or later
- A DigitalOcean account for remote deployment (or run locally without one)
- Git for cloning the repository
- pip and venv for local dependency management
- An MCP client such as Claude Desktop or Cursor
Clone the repository
Clone the domain checker MCP server repository to your local machine.
git clone https://github.com/do-community/do-remote-mcp-server-template.git
cd do-remote-mcp-server-templateCreate a virtual environment and install dependencies
Set up a Python virtual environment and install the required packages from requirements.txt.
python -m venv venv
source venv/bin/activate # macOS/Linux
# venv\Scripts\activate # Windows
pip install -r requirements.txtRun the server locally
Start the MCP server locally to test it before deploying. By default it runs in STDIO mode for direct MCP client connection.
python domain-checker.pyDeploy to DigitalOcean App Platform (optional)
Push your repository to GitHub, then create a new app in the DigitalOcean App Platform dashboard. Select your repository, set the run command to python domain-checker.py, and set PORT=8080. The platform provides an HTTPS URL ending in /mcp.
Configure your MCP client
Add the domain checker server to your MCP client. For local use, point to the Python script. For the deployed version, use the DigitalOcean app's HTTPS /mcp URL.

}Prompts to try
Example prompts for checking domain availability once the server is connected.
- "Check if myawesome-startup.com is available"
- "Check availability for these domains: mycompany.com, mycompany.net, mycompany.org, mycompany.io"
- "I want to start a business called BlueSpark — find me available domain names"
- "Is the domain opensourcehq.dev available to register?"
- "Check 10 variations of the name 'Cloudbase' across .com, .io, and .dev TLDs"Troubleshooting Domain Availability
WHOIS lookups return inconsistent or empty results
Some TLD registries rate-limit WHOIS queries. The server uses both WHOIS and DNS resolution, so a domain may still return a result via DNS even if WHOIS is throttled. For bulk checks, add delays between requests to avoid hitting rate limits.
DigitalOcean deployment health check fails
Ensure the PORT environment variable is set to 8080 in the App Platform settings and that the run command is exactly python domain-checker.py. The app expects to listen on the port provided by the PORT environment variable.
Python virtual environment not found by MCP client
Use the absolute path to the venv Python binary in your MCP client config (e.g. /Users/yourname/projects/domain-checker/venv/bin/python). Relative paths and system Python may not have the required packages installed.
