Available components
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 Usability81
- 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 2429 tokens (~173/item across 14 items; 11 tools + 3 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 Management20
- Stability observed for 6 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 11 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 13 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a current MCP spec version (2026-07-28).Pass
- Supports UI / widget rendering.Pass
How do I install the Cheapest Domains MCP server?
Cheapest Domains is a hosted endpoint at https://www.cheapest.domains/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.

check_availability Check domain availability ~224
Check one exact domain. Cloudflare answers first; configured fallback providers, then an optional selected registrar, run only for missing facts; a taken name ends the chain. Returns separate availability and nullable premium facts with provider attempts and check times; null premium is unconfirmed, not standard tier. Evidence expires after five minutes. No price lookup, purchase or reservation.
| Name | Type | Req | Description |
|---|---|---|---|
| fresh | boolean | – | Explicitly request a fresh single-name recheck only when the user asks. Normal checks reuse five-minute evidence. Fresh checks still obey provider gates, pending claims, caller limits and cooldowns;… |
| name | string | yes | One ASCII domain label without the extension, such as myproject. Price and link tools only build links from it; availability and popularity tools send the exact domain to their providers. |
| registrar | string | – | Connected registrar ID from the registrars endpoint. Omit to compare all. |
| tld | string | yes | One covered ASCII top-level extension, such as com or .com. Multi-part suffixes and IDNs are not covered. |
No output schema declared.
No examples provided.
check_availability_batch Check a name across extensions ~185
Check one name across up to 20 extensions, reusing shared five-minute evidence. Enrichment stops once availability is known, so premium can remain null. Partial failures keep the answers received plus retry guidance, without automatic retries. cachedOnly makes no provider calls. No selected-registrar fallback, fresh mode, prices or purchases.
| Name | Type | Req | Description |
|---|---|---|---|
| cachedOnly | boolean | – | Return only existing fresh availability evidence, without provider calls, lookup admission, claims or retries. Cache misses remain Not confirmed. |
| name | string | yes | One ASCII domain label without the extension, such as myproject. Price and link tools only build links from it; availability and popularity tools send the exact domain to their providers. |
| tlds | string | yes | One to 20 distinct ASCII top-level extensions separated by commas, for the same name. Optional leading dots are accepted. No whole-catalog scans. |
No output schema declared.
No examples provided.
compare_domain_names Compare suggested domain names ~152
After checking exact names with the availability tools, compare up to 10 candidates using saved renewal-first prices and fresh cached evidence. No new availability requests; cache misses are Not confirmed. Returns standard reference offers, premium facts, dates and links. The assistant explains project fit. Split larger lists into bounded groups. Does not generate names.
| Name | Type | Req | Description |
|---|---|---|---|
| domains | string | yes | One to 10 distinct exact ASCII domains separated by commas or whitespace, such as brightkit.com,brightkit.dev. One label and one top-level extension per domain; no URLs, multi-part suffixes or IDNs. |
| maxRenewalCents | integer | – | Maximum annual renewal in integer USD cents; 1000 means USD 10. |
No output schema declared.
No examples provided.
estimate_cost Estimate domain costs ~150
Estimate new registration plus subsequent renewals for one TLD at a registrar. Returns null for unknown multi-year term totals. Not a transfer or existing-domain renewal quote.
| Name | Type | Req | Description |
|---|---|---|---|
| name | string | – | One ASCII domain label without the extension, such as myproject. Price and link tools only build links from it; availability and popularity tools send the exact domain to their providers. |
| registrar | string | yes | Connected registrar ID from the registrars endpoint. Omit to compare all. |
| tld | string | yes | One covered ASCII top-level extension, such as com or .com. Multi-part suffixes and IDNs are not covered. |
| years | integer | yes | Planning horizon in years, including initial registration. |
No output schema declared.
No examples provided.
get_domain_popularity Get domain DNS popularity ~148
Look up one exact domain in Cloudflare Radar’s global DNS popularity ranking. Returns an exact top-100 rank or a broader popularity group, categories, locations, data dates, and CC BY-NC 4.0 attribution. Not Google SEO difficulty, name competition, or availability. Missing data does not indicate zero competition.
| Name | Type | Req | Description |
|---|---|---|---|
| name | string | yes | One ASCII domain label without the extension, such as myproject. Price and link tools only build links from it; availability and popularity tools send the exact domain to their providers. |
| tld | string | yes | One covered ASCII top-level extension, such as com or .com. Multi-part suffixes and IDNs are not covered. |
No output schema declared.
No examples provided.
get_naming_guidance Get domain naming guidance ~36

Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
get_registrar_link Get a registrar search link ~142

Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
search_prices Compare renewal prices ~515
Compare standard prices, including explicitly labeled Cloudflare samples. Find affordable domain extensions and registrar offers, sorted by annual renewal by default.

|---|---|---|---|
| direction | string | – | Ascending or descending result order. Unknown totals follow priced totals in either price direction. |
