Why it is in this group

- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
Description, as the server wrote it
For a domain someone already owns: whether it's listed for sale and where (with the asking price when the sale page shows one), when it could drop, its estimated value, the realistic chance of buying it, the options in order (buy now, make an offer, backorder, have GoMain broker it, watch it) and available alternatives with prices.

Description, as the server wrote it
A rough value range for a domain, from its length, how easy it is to say, its TLD, its age and how many popular TLDs have the same name registered. Use it to set a realistic budget before trying to buy a taken name. Not a comparable-sales appraisal.

Why it is in this group

- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
Description, as the server wrote it
Check whether domain names are registered, asking each TLD's registry directly (RDAP). Returns registered, available, likely_available (no registry lookup service, but no DNS records either) or unknown, plus the registrar and dates for taken names and the cheapest prices for open ones. Up to 20 names per call. A lookup is not a reservation: names can be taken at any moment, and premium or reserved names may still be priced higher or blocked at checkout.

Description, as the server wrote it
Is a project name usable everywhere it'll be needed? Checks the domain across TLDs (with prices), GitHub, npm, PyPI and crates.io, and gives links for trademark and social-handle checks that can't be automated.

Description, as the server wrote it
The exact DNS records to add so a domain serves a website (Vercel, Netlify, GitHub Pages, Cloudflare Pages) and receives email (Google Workspace, Microsoft 365, Fastmail, Zoho, Proton), plus a starting DMARC policy. Checks live DNS to show which records are already in place and warns about clashes such as two SPF records. Values a provider generates per account are marked as such.

  What this check looks for
Description, as the server wrote it
List a domain the user owns for sale. The first call returns a DNS TXT record that proves ownership; once it's added, calling again with the same domain and email activates the listing. asking_price is shown to buyers; floor_price, the lowest offer accepted automatically, never is. Sales close through Escrow.com.
Annotations the server declares

make_offerOffer to buy a domain listed with GoMain.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
Offer to buy a domain listed with GoMain. Offers at or above the asking price buy it outright; lower offers are negotiated automatically with a counter-offer, for up to three rounds, then the seller decides. An accepted offer opens an Escrow.com transaction, so the money is only released once the domain arrives. Confirm the amount and email with the user before calling; to answer a counter-offer, pass the deal_id and status_key from the last answer.

- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
Description, as the server wrote it
Every recorded price change for one TLD, oldest first, from GoMain's daily archive. A registrar's first entry is its price when the archive began (or when it started selling the TLD); later entries are changes. Prices are per year, in US dollars unless `currency` says otherwise.

request_acquisitionAsk GoMain's brokerage to acquire a domain someone else owns.No findings
Why it is in this group
- The name "request_acquisition" says "request": a word for a change.
Description, as the server wrote it
Ask GoMain's brokerage to acquire a domain someone else owns. GoMain researches it, approaches the owner without naming the buyer, negotiates within the budget (which the owner never sees), and closes through Escrow.com. Confirm the buyer's email and budget with the user before calling. Returns a deal id and status key for broker_status.

Description, as the server wrote it
Every tracked registrar's price for one TLD, in US dollars per year, refreshed daily from 40+ registrars. Sorted by 3-year cost (first year plus two renewals) by default, because a cheap first year often hides an expensive renewal. Each offer links to where to buy.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.

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.
