Available tools 2

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

phone
phone_validate_batch
Use this when you need to validate multiple phone numbers at once (up to 50). Returns an array of validation results in JSON. Returns per number: 1. valid (boolean) 2. e164 format 3. countryCode and countryName 4. carrier name 5. lineType (mobile/landline/voip/toll-free). Example output: {"results":[{"phone":"+14155551234","valid":true,"e164":"+14155551234","countryCode":"US","carrier":"T-Mobile","lineType":"mobile"},{"phone":"invalid","valid":false}],"total":2,"validCount":1} Use this FOR bulk CRM cleaning, importing contact lists, deduplication pipelines, and batch lead validation. Do NOT use for single numbers -- use phone_validate_number instead. Do NOT use for SMS capability -- use sms_validate_number instead.

Returns: 1. valid (boolean) 2. e164 format string 3. countryCode and countryName 4. carrier name 5. lineType (mobile/landline/voip/toll-free) 6. localFormat and internationalFormat.

Phone Number Validation API — questions

Answers built from our own checks of this server.

What can Phone Number Validation API do?
It exposes 2 tools, read directly from the server on our last check. Among them: phone_validate_batch, phone_validate_number. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is Phone Number Validation API working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 33 ms. The bar chart above shows every period we have measured.
How do I connect Phone Number Validation API?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Phone Number Validation API need an API key?
No. Phone Number Validation API completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 2 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Phone Number Validation API?
It answers our handshake in 33 ms on average, which is faster than 99% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.
Is Phone Number Validation API open source?
Yes — it is published under the MIT licence, written in TypeScript and 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
