Server Configuration

Describes the environment variables required to run the server.

NameRequiredDescriptionDefault
MCP_TRANSPORTNoTransport protocol for the MCP server. Set to 'http' for self-hosting over HTTP.
DOMAIN_LOCAL_DEVNoSet to '1' to enable local development mode.

Instructions

Guidance the server publishes about itself, which clients place ahead of the tool catalog so the model reads it before choosing anything.

This server publishes no instructions, or was last inspected before Glama recorded them.

Tools

Functions exposed to the LLM to take actions

NameDescription
check_domainA

Check whether a domain name is registered, using real-time RDAP data (the IETF-standardized successor to WHOIS). Use for "is domain-x.com available/registered", "who is domain-x.com registered with", or "when does domain-x.com expire" style questions.

domain is a bare domain like "example.com" -- no protocol prefix, no path, no spaces.

If the domain is NOT registered, returns {"domain": ..., "registered": false} -- this is a normal, meaningful answer (the domain is available), not an error.

If the domain IS registered, returns {"domain", "registered": true, "status", "registered_date", "expiration_date", "last_changed_date", "registrar"}. status is a list of RDAP status codes (e.g. "active", "client transfer prohibited"). Dates are ISO 8601. registrar is the registrar's name, or null if the registry redacts it for privacy.

For obviously malformed input (not a domain -- e.g. missing a dot, has spaces, or includes a protocol like "https://"), returns a clean {"error": ...} instead of calling the API.

A4.9/5.0

Scored across 1 tool

Disambiguation5/5

With only one tool, there is no possibility of confusion between tools. The tool's purpose is clearly defined.

Naming Consistency5/5

The single tool 'check_domain' follows a clear verb_noun convention, which is consistent and descriptive.

Tool Count5/5

A single tool is perfectly scoped for a server dedicated to RDAP domain lookups. It covers the entire domain without unnecessary bloat.

Completeness5/5

The tool provides comprehensive domain information: registration status, dates, and registrar. It fully addresses the primary use cases for RDAP queries.
