How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →

Endpoint Security63
Transport & Reachability100
Schema Quality & AI Usability65
  • AI-judged instruction clarity (good).Pass
  • Context-footprint check failed: tool/resource definitions use about 608 tokens (~202/item across 3 items; 3 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
  • Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management87
  • Stability observed for 26 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
  • 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
  • 100% of tool parameters carry a description.Pass
Tool Safety100
  • No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
  • We read all 3 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
  • An AI judge read all 4 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass

Install

How do I install the io.github.johnsmalls22-rgb/domain-search-king-mcp server?

io.github.johnsmalls22-rgb/domain-search-king-mcp is a hosted endpoint at https://domainsearchking.com/api/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

MCP tools · 3 exposed · ~489 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Tool Tokens
check_domain ~95

Full due-diligence report for one domain: registration age/expiry/status (live RDAP), backlinks & authority from our own Common Crawl link graph, toxic-linker audit, website history (Wayback), trademark search links, and optional blacklist when configured. Use before buying a domain. No composite appraisal score — flags + per-section detail only.

NameTypeReqDescription
domainstringyesDomain to check, e.g. 'example.com'.

No output schema declared.

No examples provided.

find_available_domains ~123

Generate brandable .com domain names for a business idea and return ONLY the ones that are currently AVAILABLE to register (verified live against the Verisign RDAP registry). Give a keyword and, ideally, a short description of the business for better names.

NameTypeReqDescription
countintegerHow many names to return (1-24). Default 12.
descriptionstringOptional. What the business does, e.g. 'a cozy late-night coffee roaster'.
keywordstringyesCore keyword or seed word, e.g. 'coffee'.

No output schema declared.

No examples provided.

find_available_domains_by_pattern ~271

Exhaustively enumerate EVERY available domain matching a keyword PATTERN, across TLDs — the thing most domain tools/MCPs can't do. Give a keyword (or several) and a position: 'starts' (keyword+word, e.g. Bearoak), 'ends' (word+keyword, e.g. Oakbear), 'contains' (keyword inside a longer invented word, e.g. Oakbearen), or 'all'. Every candidate is verified live against the registry; only AVAILABLE domains are returned, grouped by TLD. Checks .com and .net by default.

NameTypeReqDescription
keywordstringyesKeyword(s) to build around, e.g. 'bear' or 'bear, bigbear' (comma/or-separated for several).
limitintegerMax available domains to return (1-200). Default 60.
positionstringWhere the keyword sits: starts-with, ends-with, contains, or all. Default 'all'.
tldsarrayWhich TLDs to enumerate (up to 6, any real TLD: com, net, org, io, ai, co, app, dev, xyz, store, shop, tech, blog, me, de, uk...). Default ['com','net'].

No output schema declared.

No examples provided.

Common questions

What is the io.github.johnsmalls22-rgb/domain-search-king-mcp server?

Domain search MCP: .com names verified available live via Verisign RDAP - not AI guess lists. This page covers its hosted endpoint (https://domainsearchking.com/api/mcp).

Is the io.github.johnsmalls22-rgb/domain-search-king-mcp server safe to use?

io.github.johnsmalls22-rgb/domain-search-king-mcp scores 74 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

What tools does the io.github.johnsmalls22-rgb/domain-search-king-mcp server expose?

io.github.johnsmalls22-rgb/domain-search-king-mcp exposes 3 tools: find_available_domains, find_available_domains_by_pattern, check_domain. Their descriptions and schemas cost roughly 489 tokens of context every time the server is loaded.

Does the io.github.johnsmalls22-rgb/domain-search-king-mcp server require authentication?

No. We connected to io.github.johnsmalls22-rgb/domain-search-king-mcp without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

Is the io.github.johnsmalls22-rgb/domain-search-king-mcp server still maintained?

io.github.johnsmalls22-rgb/domain-search-king-mcp is still listed as active in the MCP registry. We last reached this channel on 21 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
