Frequently Asked Questions about FastDomainCheck MCP Server

Q: What is FastDomainCheck MCP Server?

A: FastDomainCheck MCP Server is an implementation of the Model Context Protocol (MCP) that allows AI tools to securely check domain name registration status in bulk.

Q: What is MCP?

A: MCP (Model Context Protocol) is an open protocol that standardizes how applications provide context to Large Language Models (LLMs), enabling AI models to interact with external data sources and tools.

Q: What are the key features of FastDomainCheck MCP Server?

A: Key features include bulk domain registration status checking, dual verification using WHOIS and DNS, support for IDN (Internationalized Domain Names), a concise output format, and built-in input validation and error handling.

Q: How does the dual verification process work?

A: The server first queries the WHOIS database for domain registration information. If the WHOIS query fails, it falls back to DNS queries to verify the domain’s status.

Q: What is the input format for checking domain registration status?

A: The input is a JSON object containing a list of domain names to check. For example:

{ “domains”: [“example.com”, “test.com”] }

Q: What is the output format?

A: The output is a JSON object containing the results for each domain name. For example:

{ “results”: { “example.com”: { “registered”: true }, “test.com”: { “registered”: false } } }

Q: How many domains can I check in a single request?

A: You can check a maximum of 50 domains per request.

Q: What happens if I exceed the maximum domain limit?

A: The server will return an error indicating that the request contains more than 50 domains.

Q: What types of errors does FastDomainCheck MCP Server handle?

A: The server handles errors such as empty domain lists, exceeding the maximum domain limit, empty domain names, domain names exceeding 255 characters, and result serialization failures.

Q: How do I configure FastDomainCheck MCP Server with Claude Desktop?

A: You need to modify the claude-desktop-config.json file to specify the path to the FastDomainCheck MCP Server binary. The exact steps are outlined in the documentation.

Q: Where can I download the FastDomainCheck MCP Server binary?

A: You can download the binary file from the release page on the project’s GitHub repository.

Q: Does FastDomainCheck MCP Server support IDNs (Internationalized Domain Names)?

A: Yes, FastDomainCheck MCP Server fully supports IDNs.

Q: How long does it take to check a domain?

A: Domain checks typically take approximately 0.3-1 second per domain.

Q: What is the timeout for WHOIS and DNS queries?

A: The WHOIS query timeout is set to 10 seconds.

Q: Can I use FastDomainCheck MCP Server with other AI tools besides Claude?

A: Yes, FastDomainCheck MCP Server can be used with any AI tool that supports the Model Context Protocol (MCP).

Q: Where can I find the Python version of this project?

A: The Python version is available on PyPI as fastdomaincheck-mcp-server.

Q: What are the development requirements for building FastDomainCheck MCP Server from source?

A: You need Go 1.16 or higher, network connectivity, and the project dependencies listed in the documentation.
