CamelMailer MCP Server

Model Context Protocol server for CamelMailer — lets AI assistants like Claude send and inspect transactional email. Works with the CamelMailer cloud and any self-hosted instance.

Setup

You need a server API key from your CamelMailer dashboard.

Claude Desktop

Add to claude_desktop_config.json (Settings → Developer → Edit Config):

{
  "mcpServers": {
    "camelmailer": {
      "command": "npx",
      "args": ["-y", "camelmailer-mcp"],
      "env": {
        "CAMELMAILER_API_KEY": "cm_xxxx"
      }
    }
  }
}

Until the packages land on npm, use the GitHub source instead: "args": ["-y", "github:camelmailer/camelmailer-mcp"]

Claude Code

claude mcp add camelmailer -e CAMELMAILER_API_KEY=cm_xxxx -- npx -y camelmailer-mcp

Self-hosted instances

Point the server at your own instance (defaults to https://app.camelmailer.com):

"env": {
  "CAMELMAILER_API_KEY": "cm_xxxx",
  "CAMELMAILER_BASE_URL": "https://mail.example.com"
}

Tools

Example prompts:

Send a plain-text email from billing@acme.com to ada@example.com thanking her for the purchase.

Why did yesterday's emails to @gmail.com addresses bounce?

What's our DMARC pass rate for acme.com this month?

Errors

API failures come back as tool errors carrying the stable CamelMailer error code (Unauthorized, NotFound, ValidationError, …), so the assistant can react — nothing crashes the server.
