Buy UK eSIM

BuyUKeSIM runs a Model Context Protocol (MCP) server, so any MCP-capable AI assistant - Claude, ChatGPT, Cursor, VS Code Copilot, Gemini CLI and others - can work with our eSIM catalogue directly. Point your assistant at one endpoint and it can search plans, list coverage, explain the UK Number, and check an order, all in plain language.

The public tools need no key and move no money. A second, authenticated set of tools adds a prepaid, crypto-funded agent wallet so an assistant can fund a balance and buy a travel/data eSIM on your behalf. There is no account and no KYC. This page is the full reference: endpoints, setup per client, every tool, authentication, runnable examples, error handling and FAQ.

Requires a local install: run the server on your machine, then point your client at it.
