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. How we score → Why this is hard to score →
Endpoint Security80
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- 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. See how to fix → View diagnostics → Partial
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability65
- AI-judged instruction clarity (excellent).Pass
- 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. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management48
- Stability check failed: schema churn in the 20 days we've observed: 1 tool removals, 0 breaking changes, 0 auth/transport breaks, 1 additions. See how to fix → Fail
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 6 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 7 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a current MCP spec version (2026-07-28).Pass

check_number Check if a phone number is available ~257
Check one US or Canadian phone number, toll free or local, by digits or by its spelling (877-393-7552 or 877-EYES-LLC). Use it when someone asks whether a number is available, what it costs, or what it is today. 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.

Returns the current holder, each earlier span, newest first, and a link to the number's page on Resporgs.com.

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.

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.

watch_number Get a notification when a phone number changes ~289
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.
| Name | Type | Req | Description |
|---|---|---|---|
| string | yes | The person's email address. The confirm email and the notifications go there. | |
| name | – | – | Optional: the person's first name, for the emails. |

How do I install the VanityNumbers.com MCP server?
VanityNumbers.com is a hosted endpoint at https://vanitynumbers.com/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

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.
