Overview

AI-generated overview

Truncus lets an AI assistant send transactional email, validate addresses, track delivery and manage sending domains from a local MCP process.

What you can do
  • Send transactional emails on behalf of an agent
  • Validate email addresses before sending
  • Track delivery status of sent messages
  • Manage sending domains
When to use it
Useful when an assistant needs to send transactional email such as notifications or confirmations, or to check addresses and delivery status through a Truncus account.
Requirements
Runs as a local stdio process (npm package @truncus/mcp-server) on a desktop machine. Requires a Truncus account and an API key supplied in the TRUNCUS_API_KEY environment variable. Network access to the Truncus service is needed.
Before you install
The server holds an API key that can send mail from your domains; keep TRUNCUS_API_KEY private. Sending email is an outward-facing action that reaches real recipients and may incur costs or affect sender reputation. Domain management can change DNS or sending configuration.

Installation

In SourceWeft

  1. Open Truncus in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declared10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.
