## How to connect it

Runs on your machine over stdio, launched by your MCP client.

### Claude Code

```sh
claude mcp add mailtrap -- npx -y mcp-mailtrap
```

Most servers need an API key passed as an environment variable — check the README for the exact variable names. Add `--scope user` to make it available in every project.

### Claude Desktop

Open **Settings → Developer → Edit Config** and add the server to `claude_desktop_config.json`, then restart Claude Desktop:

```json
{
  "mcpServers": {
    "mailtrap": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-mailtrap"
      ],
      "env": {
        "API_KEY": "…"
      }
    }
  }
}
```

### Cursor

Add to `.cursor/mcp.json` in your project, or `~/.cursor/mcp.json` for every project:

```json
{
  "mcpServers": {
    "mailtrap": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-mailtrap"
      ],
      "env": {
        "API_KEY": "…"
      }
    }
  }
}
```

### VS Code

Add to `.vscode/mcp.json`, then pick the server from Copilot's agent-mode tools menu:

```json
{
  "servers": {
    "mailtrap": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "mcp-mailtrap"
      ]
    }
  }
}
```

### ChatGPT

ChatGPT connects to **remote servers only**, and this one runs on your machine. Either expose it through an MCP gateway that gives it a public URL, or use a client with native local support (Claude or Cursor).

## How we know

Published to the MCP Registry under Mailtrap's verified namespace io.mailtrap as the npm package mcp-mailtrap (maintained by the mailtrap npm account); docs.mailtrap.io/for-ai-agents/tools/mcp-server documents npx -y mcp-mailtrap and links the mailtrap/mailtrap-mcp repo.
