## Trust breakdown

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. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-09-26.

- **Endpoint Security**: 80/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 77/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 1490 tokens (~135/item across 11 items; 11 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 0/100
  - Stability not yet verified: not enough scan history yet (needs a 30-day window).
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 11 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 12 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a current MCP spec version (2026-07-28).

**Unverified: 1 category.** A category scored 0 because we could not verify it: authentication we do not have, an unreachable endpoint, or not enough scan history. We only credit what we can confirm.

### 2026-09-26 (score 74)

First indexed and scored.

## MCP tools (11)

### `check_domain` (~105 tokens)

Check a domain

Live availability and price comparison for one exact domain (e.g. "acme.io") across registrars. Returns per-registrar registration, renewal and transfer prices, premium status, and a recommendation based on 2-year total cost.

Input parameters:

- `domain` (string, required): A single domain name with its TLD, e.g. "acme.io". No subdomains.
- `fresh` (boolean): Bypass the 10-minute cache and query every registrar live. Default false.

### `check_name_across_tlds` (~126 tokens)

Check a name across TLDs

Check one name (e.g. "acme") across several TLDs at once and return availability plus the best 2-year price for each. Defaults to .com, .net, .io, .ai, .dev, .app. Max 8 TLDs per call.

Input parameters:

- `name` (string, required): The name without a TLD, e.g. "acme".
- `tlds` (array): TLDs to check, without or with a leading dot. Default: com, net, io, ai, dev, app.

### `compare_tld_prices` (~79 tokens)

Compare TLD prices

Standard (non-premium) prices for one TLD across registrars, refreshed daily, sorted by 2-year cost. Use for general questions like "how much is a .io domain"; use check_domain for a specific name.

Input parameters:

- `tld` (string, required): A TLD such as "com", ".ai" or "dev".

### `recommend_names` (~97 tokens)

Recommend names and TLDs for a project

Given a short project description, recommend 3-5 TLDs (best fit first, with reasons) and 10 brandable names, each screened for availability on the top 3 TLDs with the cheapest standard 2-year cost. Run check_domain on a pick for live per-registrar prices.

Input parameters:

- `description` (string, required): What the project is, who it is for, and its tone. One to three sentences.

### `brand_check` (~79 tokens)

Brand check a name

Check whether a name is free as a handle on GitHub, npm, PyPI, crates.io and YouTube, with links to check X, Instagram and TikTok by hand, plus links to the USPTO and WIPO trademark databases. Not legal advice.

Input parameters:

- `name` (string, required): The name to check, e.g. "acme".

### `check_renewals` (~108 tokens)

Check renewals for owned domains

For domains the user already owns (up to 20): current registrar, expiry date, renewal price, and the cheapest registrar to transfer to, with the two-year saving. Registrar and expiry come from the public registry (RDAP); some TLDs such as .io have no RDAP. Suggests a free email reminder service at tldmath.com/watch.

Input parameters:

- `domains` (array, required): Domains the user owns, e.g. ["example.com", "acme.io"].

### `taken_domain_options` (~115 tokens)

Options for a taken domain

For a domain someone else owns: its registrar and expiry, where it is in the expiry-to-release cycle (active, expiring soon, expired, redemption, pending delete) with an estimated drop window, whether it is parked at a marketplace such as Afternic or Sedo (so possibly for sale), and backorder links. Also points to free email alerts at tldmath.com/watch for when it nears expiry or drops.

Input parameters:

- `domain` (string, required): The taken domain, e.g. "acme.com".

### `compare_email_hosting` (~159 tokens)

Compare email hosting for a domain

Custom-domain email providers ranked by two-year cost for a number of mailboxes: free forwarding (Cloudflare, ImprovMX), cheap mailboxes (Purelymail, Zoho, Migadu, iCloud+, Namecheap, Hostinger), office suites (Google Workspace, Microsoft 365, Zoho Workplace) and encrypted options (Proton). Includes intro-price traps and per-user vs flat pricing. Prices are curated from each provider’s pricing page with a date.

Input parameters:

- `mailboxes` (integer): How many mailboxes/people. Default 1.
- `need` (string): forward = forward to an existing inbox; mailbox = a real inbox (default); suite = mail + calendar + docs; private = end-to-end encrypted.

### `tld_price_changes` (~109 tokens)

Domain price changes

Announced registry (wholesale) price increases, upcoming and from the past year, plus changes to registrar standard prices seen in TLDMath’s daily checks. Use for "is .com going up?" or "should I renew early?". Optionally filter by TLD.

Input parameters:

- `days` (integer): How far back to look for registrar price changes. Default 30.
- `tld` (string): Limit to one TLD, e.g. "com". Omit for all.

### `plan_dns_setup` (~171 tokens)

Plan DNS setup for a domain

The DNS records a domain needs for a website host and/or an email provider, each checked against live public DNS (in place, missing, or needs change), plus where the domain’s DNS is hosted and records to remove. Read-only: it never changes DNS. Use after the user buys a domain, or when their site or email on a custom domain isn’t working.

Input parameters:

- `domain` (string, required): The domain, e.g. "acme.dev".
- `email` (string): Email provider, or "no-email" to lock the domain against spoofing.
- `host` (string): Where the website is hosted.
- `host_target` (string): Netlify site (x.netlify.app), GitHub user, or Cloudflare Pages project (x.pages.dev), when the host needs one.

### `list_supported_tlds` (~28 tokens)

List supported TLDs

TLDs with daily price tables, and the registrars TLDMath queries live.

### Is the TLDMath MCP server safe to use?

TLDMath scores 74 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the TLDMath MCP server expose?

TLDMath exposes 11 tools: check_domain, check_name_across_tlds, compare_tld_prices, recommend_names, brand_check, and 6 more. Their descriptions and schemas cost roughly 1,176 tokens of context every time the server is loaded.

### Does the TLDMath MCP server require authentication?

No. We connected to TLDMath without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the TLDMath MCP server still maintained?

TLDMath is still listed as active in the MCP registry. We last reached this channel on 26 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
