Overview

AI-generated overview

Remote UniOne MCP server that lets an AI assistant send transactional email and manage domains, templates and webhooks.

What you can do
  • Send transactional email through UniOne from an assistant.
  • Manage sending domains in the UniOne account.
  • Work with email templates.
  • Manage webhooks for delivery events.
When to use it
Useful when you want an assistant to trigger transactional email or adjust UniOne sending setup (domains, templates, webhooks) without leaving the chat, for example during development or support workflows.
Requirements
Remote streamable HTTP endpoint at mcp.unione.io; no local package. Requires a UniOne account and authentication: OAuth sign-in, or an Authorization header carrying a Bearer UniOne API key instead.
Before you install
The server can send real email and change account configuration such as domains, templates and webhooks, so actions have real-world effects. The Authorization header carries a UniOne API key secret; keep it private and prefer OAuth where possible. Email content and account data are handled by UniOne as a third party.

Installation

In SourceWeft

  1. Open UniOne in the dashboard and add it to a workspace.
  2. Connect the required credentials. They are stored privately and never shown on public pages.
  3. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.unione%2Fmcp/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config. The client completes OAuth sign-in on first connect.

Tools

0
This server asks you to sign in, so SourceWeft could not read its tools without an account and has not indexed them. What a connected account sees can depend on that account and its permissions.
