      "url": "https://api.spacepost.dev/mcp",
      "headers": {
        "Authorization": "<value>"
      }
    }
  }
}

npm

claude mcp add -e SPACEPOST_API_KEY=<your-spacepost-api-key> mcp -- npx -y @spacepost/[email protected]

Or add it to your MCP config (Claude Desktop, Cursor, VS Code):

{
  "mcpServers": {
    "mcp": {
      "command": "npx",
      "args": [
        "-y",
        "@spacepost/[email protected]"
      ],
      "env": {
        "SPACEPOST_API_KEY": "<your-spacepost-api-key>"
      }
    }
  }
}

Environment variables:
SPACEPOST_API_KEY (required) – SpacePost API key (sp_live_...), created in the SpacePost dashboard under API keys. A sending_access key limits the server to sending.
SPACEPOST_READ_ONLY – Set to true to expose only read tools (GET endpoints).
SPACEPOST_TOOLSETS – Comma-separated API areas to expose, e.g. emails,domains.
SPACEPOST_PERMISSION – Set to sending_access to expose only the tools a sending_access key can call.
SPACEPOST_DEFAULT_FROM – Default sender, e.g. Acme <[email protected]>, used when a send omits from.

Replace placeholders in <angle brackets> with your own values. Review what a server can access before you enable it.
