Check whether phone numbers are registered on WhatsApp, from your AI agent.
让 AI 助手查询手机号是否注册了 WhatsApp，支持单个验证、批量任务和余额查询。
Web executable，通过 Streamable HTTP。 远程服务在工作区中配置后即可从网页运行时运行。
把这段提示词粘贴到 Claude Code、Codex、Cursor 等智能体，或 SourceWeft 对话中。智能体会读取该服务器的安装指南，先向你展示发布者、端点和登录方式，经你同意后再把它添加到你的客户端。密钥不会写进任何命令。
阅读 https://sourceweft.com/mcp/app.numradar%2Fmcp/install.md，并按其中说明把这个 MCP 服务器接入我的客户端。修改任何配置之前，先告诉我它的发布者、端点和登录方式，等我确认。不要把 API 密钥写进命令或我会提交的文件；问我密钥应从哪里获取。把它添加到你客户端的 mcpServers 配置中。 客户端会在首次连接时完成 OAuth 登录。

}Check whether phone numbers are registered on WhatsApp, from your AI agent.
numradar answers one question well: is this number on WhatsApp? This is its Model Context Protocol server, so an agent can ask that question directly — validating a list, auditing contacts before a campaign, or checking a balance before spending it.
Create a key at numradar.app/app/keys.
numradar runs a hosted MCP server. No package, no local process, no version to go stale on anyone's laptop:
Point your client at that URL with an Authorization: Bearer nr_live_... header and you are done.
The npm package exists for one real case: clients whose config file accepts a command to
spawn but not a URL. claude_desktop_config.json is the common one. If you are editing a file
like that, you need the package:
Configuration for 15 verified clients — Claude Code, Cursor, Windsurf, Zed, VS Code, Cline and the rest — is at numradar.app/mcp-server.
Clients that support MCP prompts surface these as slash commands.
One credit per definitive answer — registered or not registered. Beyond that:
Numbers should be E.164 (+14155550100). Past a handful, prefer bulk_validate over a loop of
validate_number: it is one job to poll rather than N round trips.
The API key is a bearer credential for your account. --token puts it in your shell history and in
whatever config file spawns the process — prefer NUMRADAR_API_KEY from a secret store where your
client supports it. Keys are revocable from
the dashboard; revoke immediately if one is exposed.
Every tool call is authenticated, rate-limited and billed through numradar's ordinary public REST
API. The MCP server does not embed the checker and has no separate billing path, so an agent
calling a tool is treated exactly like a backend calling curl.
This is the home of the npm package — its issue tracker and documentation. The server's source lives in a private monorepo and is not published here.
Found a bug, or a client whose configuration does not work? Open an issue.

Check in real time whether a single phone number is registered on WhatsApp. Returns existence, business-account details when present, and country metadata. Uses one validation from the plan allowance per definitive answer; malformed numbers are rejected without being counted.
phone必填Queue up to 10,000 phone numbers for asynchronous validation. Returns a job id immediately — poll get_job_status for progress and results. One validation per definitive result; duplicates are collapsed before counting. A job runs at the plan's bulk pace, 4 to 20 rows a minute and slower than validate_number on purpose, so a long list takes hours: tell the person, and check back rather than waiting in a loop.
phones必填Fetch progress counters for a bulk job, and optionally the per-number results. Free — a read uses no validations, but it does count against the account's per-minute request limit, so check about once a minute rather than in a loop: a job only moves at its plan's pace. Call with include_results once status is "completed".
limitjob_id必填include_resultsList this account's recent bulk jobs with their status counters. Free.
无需输入参数。
Return how many validations this account can still spend. total_available is everything left this period: the monthly plan allowance, any rollover, and any prepaid balance. Free. Check this before queueing a large batch — a job stops when the allowance runs out.
无需输入参数。
