Overview

AI-generated overview

A remote MCP server that lets an assistant search, compare and recommend Simsima travel eSIM data plans for over 190 destinations and produce a checkout link.

What you can do
List covered destinations with entry prices and product pages, and get coverage, operators, top-up availability and entry price for one destination or ISO country code. Search eSIM plans for a country, region or global plan, cheapest first, filtered by price, data, validity and unlimited data. Fetch a single plan by SKU and recommend plans for a trip from its length in days and expected data usage. Build a checkout link to a plan's page on simsima.io with the plan preselected for the user to review and buy.
When to use it
Useful when someone planning travel asks which eSIM data plan fits their trip, wants to compare prices and data allowances across destinations, or needs to check whether an eSIM works in a given country before buying.
Requirements
A remote endpoint at mcp.simsima.io over streamable HTTP; no package, environment variables or headers are declared, and no authentication is declared. Network access to the endpoint and to simsima.io for the checkout links is needed.
Before you install
The checkout link leads to a real purchase page where the user pays Simsima; the server itself places no order and takes no payment. Plan prices, coverage and availability come from Simsima and may change. No credentials are requested by the declared configuration.

Installation

In SourceWeft

  1. Open Simsima Connectivity in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.Willyfab%2Fsimsima-connectivity/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config.
