Remote MCP server for Claude, Cursor, VS Code, and any MCP client. Ask for business name ideas and get back only .com domains that are actually available to register right now. Every result is checked live against the Verisign RDAP registry before you see it. Built because AI models hallucinate: ~89% of AI-suggested domains are already taken. Three tools: find_available_domains, find_available_domains_by_pattern, check_domain. Remote HTTP, no API key, nothing to install.

MCP readiness

F · 16/100

Readiness is how fully this listing follows its protocol and how it behaved in our probes over 30 days. It is shown for reference and does not move it in search. Search order and leaderboards use the separate quality grade (here E, 13.0/100), which weighs availability, conformance, p95 speed and descriptor. How the two differ

Valid MCP handshake	0/10	initialize did not answer cleanly (HTTP 405).
Live MCP endpoint	5/25	Endpoint answers, but not with MCP JSON-RPC (123 ms).
Protocol revision	0/10	No protocol revision reported by initialize.
Signed descriptor	n/a	No MCP standard defines a signed server descriptor.
Uptime (30 days)	0/15	0/22 probes succeeded over 30 days (0%).
Tool declaration	0/10	No tools listed by tools/list.
Verified identity	5/10	Publisher declared (repository, package or homepage); claim this listing to verify domain control.
Freshness + modern flags	4/5	seen in a source within 7 days.
Auth declaration	0/5	How to authenticate is not stated.

Applicable criteria total 90 points, scaled to 100.

Responsiveness: Responsive (123 ms; bands ≤2.5 s, ≤5 s, ≤8 s, slower; penalty only).

Measured 2026-11-11.

Nine criteria, the same as the A2A readiness score, read from our daily MCP probe (initialize + tools/list) and 30-day probe history. No MCP standard defines a signed server descriptor, so that criterion is n/a and the other 90 points are scaled to 100. Grades: A>=90, B>=75, C>=60, D>=40, F<40. Display only: search order uses the quality grade.

Compared with peers

Against 53,021 reachable MCP servers in our daily snapshot (2026-11-12 01:39 UTC). Display only; it does not change search order.

Readiness: Higher than 0% of peers; This listing 16 · peer median 81
Latency: Faster than 86% of peers; This listing 123 ms · peer median 326 ms

Where it loses the most points, and how to win them back

Live MCP endpoint −20 — Answer initialize and tools/list at the declared endpoint.
Now: Endpoint answers, but not with MCP JSON-RPC (123 ms).
Uptime (30 days) −15 — Stay reachable in our daily probes.
Now: 0/22 probes succeeded over 30 days (0%).
Valid MCP handshake −10 — Complete the MCP handshake without errors.
Now: initialize did not answer cleanly (HTTP 405).
