You can search prepaid data plans by destination country, filter by data, validity and price, read current plan details and get a link where the customer can review and buy a plan.

It runs as a hosted streamable HTTP endpoint at https://offwegosim.com/mcp, and no sign-in or API key is needed. ## What it can do - Search travel eSIM plans by two-letter country code - Filter by minimum data, validity days and maximum USD price - Read current public details for a plan - Get a checkout link for a plan - Falls back to regional bundles when no country plan exists ## Tools (3) - `search_plans`: Find prepaid travel eSIM plans by ISO country code, with optional data, validity and price filters. (read-only) - `get_plan`: Read current public details for a plan ID returned by search\_plans. (read-only) - `get_checkout_link`: Return a URL where the customer can review and buy an available eSIM; creates no order. (read-only) ## Example prompts - "Find eSIM plans for Japan with at least 5 GB under $15." - "What is the cheapest eSIM for Italy lasting 14 days?" - "Show details for that plan and give me the checkout link." - "Compare eSIM options for Thailand with at least 10 GB." ## Install ### Claude Code 1. Run this in a terminal, in your project folder: ```bash claude mcp add --transport http offwegosim https://offwegosim.com/mcp ``` 2. Start Claude Code and type `/mcp`. **offwegosim** should show as connected. Add `--scope user` to make it available in every project, not just this one. ### Claude Desktop 1. Open **Customize → Connectors**, click **+ Add**, then **Add custom connector**. 2. Name it **OffWeGoSIM** and paste this URL: ```url https://offwegosim.com/mcp ``` 3. Click **Add**. Its tools appear in the chat’s tools menu. Claude Desktop’s JSON config file only starts local servers. Remote servers go through Connectors, and connectors you add on claude.ai show up here too. ### claude.ai 1. Open the connector form on claude.ai. This button fills in the name and URL for you: [Add to claude.ai]() (opens connector settings) 2. Check that the URL reads `https://offwegosim.com/mcp` and click **Add**. 3. Turn it on in a chat from the tools menu. Free plans allow one custom connector. On Team and Enterprise plans an owner adds it under **Organization settings → Connectors**. ### ChatGPT 1. On chatgpt.com, go to **Plugins**, select **+**, then **Add custom MCP server**. 2. Enter a name for the server. 3. Under **Connection**, paste `https://offwegosim.com/mcp` as the server URL, then for authentication choose **No authentication**. 4. Check **I understand and want to continue**, then select **Create as a plugin**. Whether you can add a custom MCP server depends on your ChatGPT plan and your workspace permissions (in Business workspaces, admins and owners can). ### Cursor [Add to Cursor]() (opens Cursor) Or add it by hand to `~/.cursor/mcp.json` (all projects) or `.cursor/mcp.json` (this project): `mcp.json`: ```json { "mcpServers": { "offwegosim": { "url": "https://offwegosim.com/mcp" } } } ``` ### VS Code [Install in VS Code]() (opens VS Code) Or from a terminal: ```bash code --add-mcp '{"name":"offwegosim","type":"http","url":"https://offwegosim.com/mcp"}' ``` Or commit it to the repo in `.vscode/mcp.json`: `.vscode/mcp.json`: ```json { "servers": { "offwegosim": { "type": "http", "url": "https://offwegosim.com/mcp" } } } ``` ### Devin Desktop 1. Add it to `~/.config/devin/mcp_config.json` (macOS and Linux) or `%APPDATA%\devin\mcp_config.json` (Windows): `mcp_config.json`: ```json { "mcpServers": { "offwegosim": { "serverUrl": "https://offwegosim.com/mcp" } } } ``` 2. Refresh the MCP server list in Cascade. Devin Desktop is the new name for Windsurf. It reads `serverUrl` (or `url`) for remote servers. ### Codex ```bash codex mcp add offwegosim --url https://offwegosim.com/mcp ``` Or edit `~/.codex/config.toml` directly: `config.toml`: ```toml [mcp_servers.offwegosim] url = "https://offwegosim.com/mcp" ``` ### Gemini CLI ```bash gemini mcp add --transport http offwegosim https://offwegosim.com/mcp ``` This adds it to the current project. Add `-s user` to use it everywhere. ### Any client Most clients accept this shape. Some name the URL field differently: `serverUrl` in Devin Desktop, `httpUrl` in Gemini CLI’s settings file. ```json { "mcpServers": { "offwegosim": { "type": "http", "url": "https://offwegosim.com/mcp" } } } ``` Zed puts servers under `context_servers` in its settings. Cline needs `"type": "streamableHttp"`, or it assumes SSE. Client only starts local servers? Bridge it with `npx -y mcp-remote https://offwegosim.com/mcp`. ## Recent changes - 2026-11-04 02:25 UTC: Tracking started: 3 tools read. Source: automatic check.
