sendscape-mcp

A local MCP server for Sendscape. It lets Claude Code, Claude Desktop, Cursor and other MCP clients send email, and attach files and inline images straight from your computer.

The hosted Sendscape MCP server (https://api.sendscape.ai/mcp) runs on our side and cannot read your disk. This package runs on your machine, reads the files your assistant names and sends them through the public API. Nothing is stored on Sendscape.

Install

You need Node.js 20+ and an API key from the Sendscape dashboard (API Keys).

Claude Code

claude mcp add sendscape \
  -e SENDSCAPE_API_KEY=ss_xxxxxxxxx \
  -e SENDSCAPE_FROM="Acme <hello@acme.com>" \
  -- npx -y sendscape-mcp

Attachments

{
  "to": "ali@example.com",
  "subject": "Your invoice",
  "html": "<img src=\"cid:logo\"><p>Invoice attached.</p>",
  "attachments": [
    { "localPath": "/Users/me/Desktop/invoice.pdf" },
    { "localPath": "/Users/me/Pictures/logo.png", "content_id": "logo" }
  ]
}

• Exactly one of localPath, url, content per attachment.

• content_id makes an inline image: <img src="cid:ID">.

• Max 10 files, 10 MiB total; executables and scripts are refused. The server checks this before sending.

• File contents are never returned to the model, only the name and size.

• Every send carries an Idempotency-Key.

To test without emailing anyone, send to delivered@sandbox.sendscape.ai.
