## 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 2026-11-05.

- **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. Nothing on it is marked destructive, but we can't show that an anonymous caller can only read: full credit needs the server to list at least one tool and every tool to be verifiably read-only. We use a best-effort check of tool names and descriptions to tell read-only tools from tools that change things, so some genuinely read-only tools may not get full credit. Names that start with a read verb (get, list, read, search and similar) and accurate readOnlyHint annotations help. Meet that to earn full credit, or require authorisation.
  - 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**: 65/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 1509 tokens (~251/item across 6 items; 6 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 48/100
  - Stability check failed: schema churn in the 20 days we've observed: 1 tool removals, 0 breaking changes, 0 auth/transport breaks, 1 additions.
- **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.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 6 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 7 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).

## MCP tools (6)

### `search_vanity_numbers` (~265 tokens)

Find a phone number that spells a word

Find a new phone number for a business that spells a word, like 1-800-PLUMBER: toll free (800, 888, 877, 866, 855, 844, 833) or local in a state. Use it when someone wants a memorable or vanity number, an 800 or toll free number, or a number that spells their business name or what they do; give it that word (PLUMBER, BAKERY). Returns the word in all seven toll free area codes with each one's status and price, a recommended pick, close versions available for $49, local numbers in a state when one is given, the word's business category pages, and links to finish on VanityNumbers.com. It doesn't look up an existing business's phone number.

Input parameters:

- `email`: Optional: the person's email, if they have a confirmed notification with VanityNumbers.com. The lookup is then connected to their notifications, so their emails' suggestions fit what they're looking…
- `state`: Optional: a two-letter state or province for local numbers, like TX (CA_N or CA_S for California).
- `word` (string, required): The word or number, 3 to 15 letters or digits, like PLUMBER.

Returns its status (available, backorder, rent to own, with another vendor, in use, or for a local number the phone company first given its block, when, and the company that has it today, with each company's page on NewLocalNumbers.com), its price when it has one, and links to its history and to finish on VanityNumbers.com. When the number spells a word, it also names the word and lists numbers like it that can be ordered.

- `note`
- `number` (string)
- `page` (string)
- `source`
- `summary` (string)

### `watch_number` (~289 tokens)

Get a notification when a phone number changes

Set up a notification about a toll free or local phone number for a person who wants an email when it changes: a number they want that someone has today, or a local number whose block no phone company has been given yet. Use it when the person asks to be told about a number and gives their email address. VanityNumbers.com emails them a link to confirm, and nothing starts until they click it. Then they get what we have on it now. A toll free number is followed with the same 7 digits in all 7 toll free area codes; a local number with every version of it in its state, a check each month of whether it's still in use, and, if no phone company has its block yet, when our data shows one was given it. After that they get an email on the 15th when it or a related number has changed, and every three months to say the notification is still on. Returns whether the confirm email went out. It can't buy or reserve a number.

Input parameters:

- `email` (string, required): The person's email address. The confirm email and the notifications go there.
- `name`: Optional: the person's first name, for the emails.
- `number` (string, required): The number to be notified about, by digits or spelling, like 844-758-6237, 844-PLUMBER or 512-758-6237.

Output parameters:

- `contact` (string)
- `kind` (string)
- `label` (string)
- `number` (string)
- `page` (string)
- `request_page`
- `scope`
- `status` (string)
- `summary` (string)
- `what_next` (string)

### `request_vendor_number` (~200 tokens)

Request a number from another vendor

Pass along a person's request for a toll free number held by another vanity number vendor, the kind check_number and the searches show as with another vendor, with no list price. Use it when the person asks to request that number and gives their name and email. Bill Quimby at VanityNumbers.com reviews each request by hand to confirm it's available and what it would cost, and answers by email, usually within a day; it costs nothing to ask. Returns whether it was sent and what happens next. It can't buy or reserve the number.

Input parameters:

- `email` (string, required): The person's email address. Bill answers there.
- `message`: Optional: anything the person wants Bill to know, like what the business does.
- `name` (string, required): The person's name, for Bill's reply.
- `number` (string, required): The toll free number, by digits or spelling, like 844-393-2273 or 844-EYE-CARE.

Output parameters:

- `contact` (string)
- `label` (string)
- `meaning` (string)
- `number` (string)
- `page` (string)
- `request_id`
- `request_page`

## Common questions

### What is the VanityNumbers.com MCP server?

VanityNumbers.com is an MCP server listed in the public MCP registry as com.vanitynumbers/vanitynumbers. Find phone numbers that spell a word, toll free or local, with status, price and history. This page covers its hosted endpoint (https://vanitynumbers.com/mcp).

### Is the VanityNumbers.com MCP server safe to use?

VanityNumbers.com scores 78 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 VanityNumbers.com MCP server expose?

VanityNumbers.com exposes 6 tools: search_vanity_numbers, check_number, find_business_numbers, number_history, watch_number, request_vendor_number. Their descriptions and schemas cost roughly 1,365 tokens of context every time the server is loaded.

### Does the VanityNumbers.com MCP server require authentication?

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

### Is the VanityNumbers.com MCP server still maintained?

VanityNumbers.com is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What did VerifyMCP test on the VanityNumbers.com MCP server?

VerifyMCP ran 13 checks on VanityNumbers.com, covering TLS certificate, Authorization, HTTPS, HSTS header and 9 more. Supply Chain Security and Provenance & Transparency do not apply to a hosted endpoint, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
