Anlyon alternative
3 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.

Changes things 3Claude Code: ask
domain_infoUse this when someone asks about one existing domain: which registrar it is with, when it was registered and expires, whether it is locked, its nameservers and DNS host, its email …Reads text others writeNo findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
What it can reach
- untrusted-inputThe server marks it openWorldHint: true: it reaches things outside the server's own data.
Description, as the server wrote it Use this when someone asks about one existing domain: which registrar it is with, when it was registered and expires, whether it is locked, its nameservers and DNS host, its email setup (MX, SPF, DMARC) and whether its website answers over HTTPS. Public records only; owner contact details are not returned.
Annotations the server declares

- readOnlyHint: true
- destructiveHint: false
- openWorldHint: true

- untrusted-inputThe server marks it openWorldHint: true: it reaches things outside the server's own data.
Description, as the server wrote it Use this to check many names at once (up to 500, or one name across every ending with tlds ["all"]): whether each is already registered, from DNS and public registry records, with its registrar and expiry date. It is a quick screen, not the registrar's answer: confirm the names you will suggest with search_domains.
Annotations the server declares
- title: Screen many domain names
- readOnlyHint: true
- destructiveHint: false
- openWorldHint: true
suggest_domainsUse this when someone has a keyword or an idea but no name yet: returns domain names that fit it and can be registered now, with their prices.Reads text others writeNo findings

get_tld_infoUse this when someone asks what a domain ending (such as .com, .ai or .io) costs or what its rules are: registration, renewal and transfer price, allowed terms, days left to renew …Reads text others writeNo findings
Why it is in this group
- The name "get_tld_info" says "get": a word for reading.
What it can reach
- untrusted-inputThe server marks it openWorldHint: true: it reaches things outside the server's own data.
Description, as the server wrote it Use this when someone asks what a domain ending (such as .com, .ai or .io) costs or what its rules are: registration, renewal and transfer price, allowed terms, days left to renew after expiry, WHOIS privacy, DNSSEC and HSTS preload.
Annotations the server declares
- title: Get domain ending details
- readOnlyHint: true
- destructiveHint: false
- openWorldHint: true
search_domainsUse this when someone wants to know whether specific domain names can be registered and what they cost.Reads text others writeNo findings
Why it is in this group
- The name "search_domains" says "search": a word for reading.
What it can reach
- untrusted-inputThe server marks it openWorldHint: true: it reaches things outside the server's own data.
Description, as the server wrote it Use this when someone wants to know whether specific domain names can be registered and what they cost. Checks up to 20 names (exact domains, or a name plus endings) with the live registrar and returns, for each, whether it can be registered, the first-year and renewal price in USD, and the reason when it cannot. For many names at once, use screen_domains first.
Annotations the server declares
- title: Search domain availability and price
- readOnlyHint: true

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.
Exfil surface
Which tools read private data, which read text someone else can write, and which can send data out. One of each is a path a prompt injection can use.
No private-data, untrusted-input, outbound path in this server alone: no tool is tagged private-data or outbound.
- Reads private data0
- Reads files, mail, messages, databases, secrets, calendars or repositories.
- Reads text others write5
- Brings in text someone else can write: web pages, inbound email, messages, issues and comments.
- Can send data out0
- Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL.
Other servers in the same agent add their own tools to these paths. Audit your whole setup to see them together.
Findings
Matches of fixed checks, with the text they matched.
No check matched anything in these tool definitions. That is not a safety guarantee.
History
Changes to its tool definitions and to its remote endpoint, newest first.
No change seen yet. Its tools are rescanned every day, and a remote endpoint is looked at once a week.
Install
Pinned to version 1.0.0. Values in angle brackets are yours to fill in.
claude mcp add --transport http lookup https://nymwell.com/mcp/lookupclaude mcp add --transport http lookup https://nymwell.com/mcp/lookupRun in a terminal.
Claude Code permissions
Allow the reads, ask before a change or a way out, deny the deletes. Paste into .claude/settings.json.
{
"permissions": {
"allow": [
"mcp__lookup__search_domains",
"mcp__lookup__get_tld_info"
],
"ask": [
"mcp__lookup__screen_domains",
"mcp__lookup__domain_info",
"mcp__lookup__suggest_domains"
],
"deny": []
}
}Tools that only read are allowed, tools that change things ask first, tools that delete or cancel are denied. A read that can send data out (it takes a URL, say) asks first too. It assumes the server is installed as lookup. Review it before you use it.

Pin
Keep the decision: fail CI when the tools change, follow every change, or show a badge.
Pin in CI
Fail a build when the tools you reviewed are not the tools the server serves today.
