Email, SMS and marketing automation: campaigns, contacts, automations and stats from Claude.
Overview
Send16 connects an assistant to an email, SMS and marketing automation platform to manage campaigns, contacts, automations and stats.
- What you can do
- Manage email and SMS campaigns from the assistant
- Work with contacts and contact lists
- Set up and inspect marketing automations
- Read campaign and account statistics
- All actions run against a Send16 account through the hosted endpoint
- When to use it
- Useful when you run email or SMS marketing on Send16 and want an assistant to draft campaigns, look up contacts, check automations or pull performance stats without switching tools.
- Requirements
- A remote MCP endpoint at mcp.send16.com over streamable HTTP, with OAuth authentication. An Authorization header carrying a Send16 API key in Bearer form is required; keys are created under Settings > API keys, and the free plan works.
Installation
In SourceWeft
- Open Send16 in the dashboard and add it to a workspace.
- Connect the required credentials. They are stored privately and never shown on public pages.
- 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/com.send16%2Fsend16/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.Other MCP clients
Add this to your client's mcpServers config. The client completes OAuth sign-in on first connect.

67% of the applicable checks met
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.
