An [MCP](https://modelcontextprotocol.io) server for the [useSend](https://usesend.com) email platform (an open-source Resend/Postmark alternative). It gives any MCP client — Claude, Cursor, VS Code, Windsurf, Codex — **33 tools** for transactional email, contacts, campaigns, domains, and analytics, over stdio.

## Setup

**1. Get a useSend API key** (`us_…`) from **Settings → API Keys** at [app.usesend.com](https://app.usesend.com) (or your self-hosted instance).

**2. Add the server to your MCP client.** Almost every client uses the same JSON — paste this in and swap in your key:

```json
{
  "mcpServers": {
    "usesend": {
      "command": "uvx",
      "args": ["usesend-mcp"],
      "env": { "USESEND_API_KEY": "us_your_api_key_here" }
    }
  }
}
```

`uvx` (from [uv](https://docs.astral.sh/uv/)) downloads and runs the server from PyPI on demand — nothing to install first.

**Where does that JSON go?**

| Client | Config file |
|---|---|
| Claude Code | `.mcp.json` (project root) |
| Claude Desktop | `claude_desktop_config.json` |
| Cursor | `.cursor/mcp.json` (project) or `~/.cursor/mcp.json` |
| VS Code (Cline) | `cline_mcp_settings.json` |
| Windsurf | `~/.codeium/windsurf/mcp_config.json` |

Prefer the command line?

```bash
claude mcp add usesend --env USESEND_API_KEY=us_your_api_key_here -- uvx usesend-mcp   # Claude Code
codex  mcp add usesend --env USE…
