simsima-connectivity is a public MCP server, a connector following a standard that lets AI assistants call outside tools, that lets any AI agent browse and recommend travel eSIM data plans from a company called Simsima. An eSIM is a way to get mobile data in another country without swapping a physical phone card, and this server gives an AI chat assistant a set of tools to look through Simsima's actual product catalog. The server offers five tools an agent can call. One lists which countries or regions are covered along with the cheapest price and a link to the product. Another searches the available plans for a specific destination, with options to filter by price, amount of data, or how long the plan lasts. A third fetches full details on a single plan by its product code. A fourth recommends the best plan for a trip based on how many days someone is traveling and whether they expect to use light, medium, or heavy amounts of data. The last tool builds a link to buy a specific plan on Simsima's website, tagged so Simsima can tell the sale came from an AI agent. The server only reads catalog information and builds these tagged links: it never touches payments, order details, or account logins. Behind the scenes the server reads a public web feed that Simsima already publishes, refreshing its copy roughly every fifteen minutes, and every product link it hands back comes straight from that feed, so links should never point to a missing page. Right now it covers plans in English and French for individual countries, with regional and worldwide plans expected to come from the feed later. The project also optionally reports anonymous usage events to an analytics service if a key is configured, and stays silent if it is not. A developer can run the server locally with Node.js for testing, or deploy it as a small web service, and the project is also set up to be listed on an official public registry of MCP servers so that other AI tools can discover it automatically. It is aimed at developers building AI travel assistants or shopping agents who want their AI to browse and recommend real eSIM data plans.
