Overview

AI-generated overview

Remote MCP server for travel eSIM planning: browse esimgomobile's live plan catalog, check coverage and device support, and get trip connectivity advice.

What you can do
  • Browse, search, compare and get details on published eSIM plans, with prices and per-GB unit price
  • Recommend a plan or plan a whole trip from itinerary, days and usage, and validate an order draft as a dry run
  • Check country coverage, country networks, internet freedom, airport connectivity and free Wi-Fi hotspots
  • Estimate data usage, calculate data budget and roaming cost, and format international dialing numbers
  • Check device eSIM compatibility, carrier lock, installation steps, APN settings, dual-SIM setup and troubleshooting
  • Run network diagnostics: speed test, public IP, roaming status, latency, connection grading, captive portal and DNS leak guidance
When to use it
Useful when someone is preparing international travel and wants help choosing a travel eSIM, sizing a data plan, comparing prices, or checking whether their phone and destination are supported. Also handy for on-trip connectivity questions such as installation, APN, dual-SIM setup and public Wi-Fi safety.
Requirements
A remote Streamable HTTP endpoint; no local install. The README states no environment variables, API keys or accounts are required. Network access to the endpoint is needed, and some tools query live external sources (the esimgomobile catalog, OpenStreetMap).
Before you install
The server is a vendor-operated catalog for esimgomobile, so plan listings and recommendations favor that provider. Order validation is a dry run only: no order is placed and nothing is charged, and order creation and provisioning are not exposed. Some tools send requests to third parties, including OpenStreetMap geocoding and hotspot queries and an edge-side latency probe to a user-supplied host; the public IP tool reports the address the request arrives from. Several checks (captive portal…

Installation

In SourceWeft

  1. Open esimgomobile — Travel eSIM Tools 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/com.esimgomobile%2Fesimgomobile/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.

README

esimgomobile MCP Server

[esimgomobile]

Travel eSIM tools, plan catalog and trip planning for agents and developers.

Plan data is read live from esimgomobile's published catalog (5-minute cache) with a labeled, versioned-snapshot fallback. esimgomobile.com/pricing is authoritative. Read-only: order validation is a dry-run — no order is placed and nothing is charged. Supplier-backed operations (order creation, provisioning, QR delivery) are intentionally not exposed.
