Overview

AI-generated overview

Remote MCP server for an email outreach platform: manage contacts, build and schedule campaigns, and track deliverability.

What you can do
  • Add, bulk-add, list, remove and tag contacts, and list all tags in use
  • Create, rename, delete campaigns and manage their sequence steps (delay, subject, body)
  • Assign contacts to a campaign, schedule it, list schedules, and pause, resume, retry or process due runs
  • Add, list and remove email providers used for sending
  • Read deliverability stats (sent, opens, bounces, replies) and check SPF, DKIM and DMARC records for a domain
  • Score subjects and bodies for spam triggers, send test emails, and manage tasks and user settings such as timezone
When to use it
Useful when you want an assistant to run cold or follow-up email outreach end to end: maintaining a contact list, drafting multi-step sequences, scheduling sends, and reviewing deliverability and spam risk before launching.
Requirements
A remote endpoint at thinkandautomate.dev over streamable HTTP, with a bearer API key sent in the Authorization header. Sending requires configured email provider credentials (Gmail or Zoho APIs per the README).
Before you install
The server sends real email to real recipients and can schedule, pause or retry campaigns, so mistakes reach inboxes. It stores contact data and provider credentials. The bearer API key is a secret; keep it out of logs and shared configs. Spam and domain checks are advisory only.

Installation

In SourceWeft

  1. Open Mailcannon in the dashboard and add it to a workspace.
  2. Connect Authorization token 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.github.AinaLuc%2Fmailcannon/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
