check_availabilityCheck one exact domain.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
Description, as the server wrote it
Check one exact domain. Cloudflare answers first; configured fallbacks, then an optional selected registrar, run only for missing facts; a taken name ends the chain. Returns separate availability and nullable premium facts, provider attempts and check times; null premium is unconfirmed, not standard tier. Recheck after expiresAt (5 min; up to 30 days if taken). No prices, purchase or reservation.
Annotations the server declares
- title: Check domain availability
- readOnlyHint: false
- destructiveHint: false
- idempotentHint: false

check_availability_batchCheck one name across up to 20 extensions, reusing shared evidence.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
Description, as the server wrote it
Check one name across up to 20 extensions, reusing shared 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.
Annotations the server declares
- title: Check a name across extensions
- readOnlyHint: false
- destructiveHint: false

Description, as the server wrote it
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.

estimate_costEstimate new registration plus subsequent renewals for one TLD at a registrar.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it
Look up one exact domain in Cloudflare Radar’s global DNS popularity ranking.

12 of these tools change something. Run those as governed actions.

Declare what an action changes, and Anlyon puts it under a shared limit, binds every approval to the exact request, and grades the outcome. It works on any HTTPS API you can describe as an action.

Anlyon does not run, proxy or govern this MCP server. A tool your own code calls directly is not routed through Anlyon and is not governed by it.
