概览

AI 生成的概览

LookupLab 是一个远程 MCP 服务器，让助手通过你的 LookupLab 账户进行手机号运营商、邮箱域名、IP 网络和 DNS 查询。

可以做什么
  • 查询手机号的运营商与线路类型，可选提供美加来电者姓名信息
  • 校验邮箱地址的语法、MX 记录、一次性域名和角色地址特征
  • 查询 IP 的近似位置与网络/服务商指标
  • 检查域名的 MX、SPF、DMARC 或 DKIM 记录并报告问题
适用场景
适合在对话中做快速的数据清洁与送达性检查：验证邮箱列表、核对手机号、定位 IP 归属网络，或审查域名的邮件认证记录。每次查询都会消耗付费额度，因此更适合零散核验而非批量处理。
运行要求
远程端点 lookuplab.io，使用 Streamable HTTP，无需本地安装包。需要 LookupLab 账户、可用额度与 API 密钥，通过 X-API-Key 请求头或 Bearer 令牌提供，或在 Claude 中通过 OAuth 登录。Claude Code 方式使用 LOOKUPLAB_API_KEY 环境变量。DKIM 检查需要提供 selector。
安装前请注意
所有工具都会扣除账户额度（手机号查询按线路类型和来电者姓名扣 1 至 5 点，其他查询扣 1 点），且执行前余额须足以覆盖最高扣费。重复调用可能再次扣费，除非客户端发送稳定的 Idempotency-Key 请求头。结果不能证明身份、归属、联系同意、邮件可达或精确位置，隐私标记可能缺失。只提交你有权查询的数据，并避免把 API 密钥写入共享仓库或聊天消息。

安装

在 SourceWeft 中

  1. 打开 控制台中的 LookupLab，将其添加到工作区。
  2. 连接 X-API-Key 凭据。它们会被私密存储，绝不会在公开页面上展示。
  3. 为需要使用其工具的对话启用该服务。

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。

交给智能体安装

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/io.github.PpiNeaPpLe%2Flookuplab/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。

LookupLab integrations

[M8ven Score]

Phone carrier, email-domain, IP-network and DNS checks through LookupLab.

Find LookupLab on Smithery and in the official MCP Registry.

Claude web and Desktop

  1. Open Customize > Connectors > Add custom connector. Name it LookupLab and use https://lookuplab.io/api/mcp.
  2. Choose Sign in now and Register automatically if Claude shows authentication options. Leave a custom client ID and secret blank.
  3. On LookupLab's consent page, enter your LookupLab key and approve. Enable the connector in your chat. Try: "Check the mail records for example.com."

Your key goes only to LookupLab; Claude receives a revocable OAuth connection. On Team and Enterprise plans, an owner first adds the connector, then each member connects their account. See Claude's connector setup.

Claude Code

Set LOOKUPLAB_API_KEY privately in your environment, then merge claude-code.mcp.json into your project's .mcp.json. Start Claude Code in that project, approve LookupLab when prompted, and check /mcp. Keep the variable reference in the file; never replace it with a real key in a shared repository.

The config uses Claude Code's HTTP transport and environment expansion. Try: "Check the mail records for example.com."

Gemini CLI

Install with gemini extensions install https://github.com/PpiNeaPpLe/lookuplab-integrations. Supply your existing LookupLab API key in the extension's sensitive setting. Gemini stores this setting in its system keychain when available. Never put a key in a chat message.

Other MCP clients

Connect to https://lookuplab.io/api/mcp with Authorization: Bearer YOUR_API_KEY or X-API-Key: YOUR_API_KEY in the client's secure connection settings. The server uses Streamable HTTP with JSON responses and no SSE stream.

ChatGPT and Codex

The openai/ directory is the portable plugin package. OAuth needs an exact callback registered by LookupLab before the platform connection can run. This source package is not a claim of directory approval or publication.

Tools and costs

ToolChecksAccount credits
phone_lookupCarrier, line type; optional caller name1 for landline/VoIP/toll-free, 3 mobile/unknown; caller name adds 2
email_verifySyntax, MX and domain indicators1
ip_lookupApproximate location and network1
dns_checkMX, SPF, DMARC or DKIM1

The account needs enough balance for the maximum charge before the lookup runs. Failed/invalid results are not charged. Tools debit credits, so they are marked as operations with side effects. Duplicate calls may charge again unless your client sends a stable Idempotency-Key header for retries.

Data is not proof of a person's identity, ownership, consent to contact, guaranteed email delivery or precise location. Privacy flags can be unavailable. Supply only data you are authorized to check.
