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 Security80
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability67
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 631 tokens (~210/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 Management100
- No destabilizing schema changes in the last 30 days.Pass
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
Capabilities60
- Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28. See how to fix → Fail

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 →
check_domain Domain due-diligence report ~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.
| Name | Type | Req | Description |
|---|---|---|---|
| domain | string | yes | Domain to check, e.g. 'example.com'. |
No output schema declared.
No examples provided.
find_available_domains Find available .com names ~138
Generate brandable .com domain names for a business idea and return ONLY the ones that are currently AVAILABLE to register (checked against the Verisign RDAP registry through a caching proxy; an available answer can be up to 10 minutes old). Give a keyword and, ideally, a short description of the business for better names.
| Name | Type | Req | Description |
|---|---|---|---|
| count | integer | – | How many names to return (1-24). Default 12. |
| description | string | – | Optional. What the business does, e.g. 'a cozy late-night coffee roaster'. |
| keyword | string | yes | Core keyword or seed word, e.g. 'coffee'. |
No output schema declared.
No examples provided.
find_available_domains_by_pattern List available domains by keyword pattern ~279
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 checked against the registry (cached answers up to 10 minutes old); only AVAILABLE domains are returned, grouped by TLD. Checks .com and .net by default.
| Name | Type | Req | Description |
|---|---|---|---|
| keyword | string | yes | Keyword(s) to build around, e.g. 'bear' or 'bear, bigbear' (comma/or-separated for several). |
| limit | integer | – | Max available domains to return (1-200). Default 60. |
| position | string | – | Where the keyword sits: starts-with, ends-with, contains, or all. Default 'all'. |
| tlds | array | – | Which 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.
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.
