它在 3 项适用的基础检查中通过了 3 项。我们没有阅读代码。在添加密钥或令牌之前,请先看看这个服务器要求哪些权限,并使用只具备所需权限的密钥。
注册中心没有列出必需的密钥,不过有些服务器会在首次使用时要求你登录。
它在作者的云端运行。通过互联网连接,无需安装,但你发送的内容会经过作者的服务器。
GitHub 仓库最后更新于–,最新版本(1.22.3)于昨天进入注册中心。
支持 MCP 的应用,例如 Claude Desktop、Claude Code、Cursor 和 VS Code。它通过 URL 连接,所以接受远程 MCP 服务器的应用也可以使用,例如开启开发者模式的 ChatGPT。

Use Abstract API from Claude, Cursor, or any MCP client — email validation, phone lookup, IP geolocation, company enrichment, IBAN and VAT validation, VAT rates and calculation, exchange rates (live, conversion, historical), public holidays and time zones. Connect with the keys of the Abstract APIs you use (at least one); every call spends credits from your own plan. Hosted, no local install: connect with your own Abstract API credentials.
Live endpoint: https://abstract-api.usefulapi.io/mcp · Homepage: https://usefulapi.io/abstract-api
https://abstract-api.usefulapi.io/mcp.claude mcp add --transport http abstract-api https://abstract-api.usefulapi.io/mcp, then run /mcp to log in.{
"mcpServers": { "abstract-api": { "url": "https://abstract-api.usefulapi.io/mcp" } } }
Add only the URL. Do not add an Authorization header or an API key to the client config: the server signs you in with OAuth, and the login page asks for your Abstract API credentials.

read tools are read-only; write tools mutate data (clients should confirm them); meta tools report usage, manage your subscription or send a feature request.
| Plan | Price | Limit |
|---|---|---|
| Free | $0 | 50 tool calls / month |
| Pro (per user) | $9/mo or $90/yr (2 months free) | Unlimited* |
\*Pro has a fair use limit of 10,000 tool calls a month on this server. For more, write to support@usefulapi.io.
Pro covers this server only. Subscribe with abstractapi_upgrade (it returns a Stripe Checkout link). Cancel any time with abstractapi_cancel_subscription: Pro continues to the end of the paid period, with no refund for the current period, and running abstractapi_upgrade before then undoes the cancel. Or write to support@usefulapi.io.
