Worldcitisim eSIM

Overview

Worldcitisim eSIM is a Model Context Protocol (MCP) server: Travel eSIMs for 193 countries. Stripe + Bitcoin checkout. QR by email in 30s. No API key. Because it speaks the Model Context Protocol, AI assistants can use Worldcitisim eSIM as a set of callable tools instead of you copy-pasting between apps.

It runs locally: the npm package @worldcitisim/mcp-esim speaks MCP over stdio on your machine. No credentials are required — it works out of the box. The current release is v0.2.2, published under the MIT license, with source at isabellaliebgott/mcp-esim on GitHub.

On mcp.site, Worldcitisim eSIM sits in the Communication category. Any MCP client can use it — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed among them — via the install snippets below.
