## About

eSIM Grab is a read-only comparison service for travel eSIMs. It lets an assistant find supported destinations, compare current plans for a country or region, check a single plan's coverage, and compare options for trips across 2 to 6 countries. Results include native prices, estimated currency conversions, source links and checkout links that may earn a commission.

The server runs as a hosted Streamable HTTP endpoint at https://esimgrab.com/mcp. No sign-in or API key is needed. It is in beta, and it cannot purchase or activate eSIMs or access accounts.

## What it can do

- Look up supported country and region slugs
- Compare current eSIM plans by price, data and validity
- Filter plans by hotspot support and subscription type
- Verify a single plan and its explicit coverage
- Compare plans for multi-country trips of up to 180 days
- View prices in many currencies

## Tools (4)

- `find_destinations`: Find supported country or region slugs by name, slug or country code; up to 25 matches. (read-only)
- `search_esim_plans`: Compare current eSIM plans for one country or region, ordered by lowest total price. (read-only)
- `get_esim_plan`: Read one active plan by ID with its quote, coverage and checkout link. (read-only)
- `compare_trip`: Compare eSIM options for 2 to 6 countries in travel order, up to 180 days. (read-only)

## Example prompts

- "Find the cheapest eSIM for Japan with at least 10 GB for 7 days"
- "Compare eSIMs for a trip through France, Italy and Greece, 5 days each"
- "Which eSIM plans for Thailand allow hotspot use?"
- "Show me details and coverage for this eSIM plan ID"

## Install

### Claude Code

1. Run this in a terminal, in your project folder:

```bash
claude mcp add --transport http esim-grab https://esimgrab.com/mcp
```

2. Start Claude Code and type `/mcp`. **esim-grab** 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 **eSIM Grab** and paste this URL:

```url
https://esimgrab.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](<https://claude.ai/customize/connectors?modal=add-custom-connector&connectorName=eSIM%20Grab&connectorUrl=https%3A%2F%2Fesimgrab.com%2Fmcp>) (opens connector settings)

2. Check that the URL reads `https://esimgrab.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://esimgrab.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](<https://cursor.com/install-mcp?name=esim-grab&config=eyJ1cmwiOiJodHRwczovL2VzaW1ncmFiLmNvbS9tY3AifQ%3D%3D>) (opens Cursor)

Or add it by hand to `~/.cursor/mcp.json` (all projects) or `.cursor/mcp.json` (this project):

`mcp.json`:

```json
{
  "mcpServers": {
    "esim-grab": {
      "url": "https://esimgrab.com/mcp"
    }
  }
}
```

### VS Code

[Install in VS Code](<https://vscode.dev/redirect/mcp/install?name=esim-grab&config=%7B%22type%22%3A%22http%22%2C%22url%22%3A%22https%3A%2F%2Fesimgrab.com%2Fmcp%22%7D>) (opens VS Code)

Or from a terminal:

```bash
code --add-mcp '{"name":"esim-grab","type":"http","url":"https://esimgrab.com/mcp"}'
```

Or commit it to the repo in `.vscode/mcp.json`:

`.vscode/mcp.json`:

```json
{
  "servers": {
    "esim-grab": {
      "type": "http",
      "url": "https://esimgrab.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": {
    "esim-grab": {
      "serverUrl": "https://esimgrab.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 esim-grab --url https://esimgrab.com/mcp
```

Or edit `~/.codex/config.toml` directly:

`config.toml`:

```toml
[mcp_servers.esim-grab]
url = "https://esimgrab.com/mcp"
```

### Gemini CLI

```bash
gemini mcp add --transport http esim-grab https://esimgrab.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": {
    "esim-grab": {
      "type": "http",
      "url": "https://esimgrab.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://esimgrab.com/mcp`.
