About Abstract API MCP by usefulapi

Abstract API MCP by usefulapi is a hosted MCP server for calling Abstract API from clients such as Claude and Cursor. It provides validation, lookup, exchange-rate, holiday, and time-zone tools using the user's own API credentials and credits.

Key features

  1. 01Validate emails, IBANs, and VAT numbers
  2. 02Look up phones, IPs, and companies
  3. 03Retrieve rates and convert currencies
  4. 04Check public holidays and time
  5. 05View usage and manage subscriptions

Use cases

  1. 01Validate customer emails or tax identifiers
  2. 02Look up IP locations and company details
  3. 03Handle exchange-rate and time-zone queries

MCP support

The remote MCP server exposes Abstract API tools to clients. OAuth login uses credentials for the Abstract APIs in use, and calls consume credits from the associated plan.

Configuration

Remote servers need no local install. Pick your client, then copy the config or install in one click.

Details

From the project README

Abstract API MCP by usefulapi

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

Connect

  • Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste https://abstract-api.usefulapi.io/mcp.
  • Claude Code: claude mcp add --transport http abstract-api https://abstract-api.usefulapi.io/mcp, then run /mcp to log in.
  • VS Code: Add to VS Code.
  • Cursor and other clients: add the URL as a remote MCP server:
{
  "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.

From what the protocol is to installing your first server, these answers cover most first questions.

An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
