Send transactional email from your editor — describe the event, Sendable writes and sends it.
Overview
Sendable lets an assistant write and send transactional email from the editor by describing an event, with your data values substituted afterwards.
- What you can do
- Send transactional email by describing an event and its fields, letting the service write the message copy.
- Add new message types by naming a new event string rather than maintaining templates.
- Keep data values intact: the writing model sees field names only, and placeholders are filled in afterwards.
- Rely on a second model that checks each draft for claims the data does not support and refuses rather than guessing.
- When to use it
- Useful when you want an assistant in Claude Desktop or Cursor to send transactional messages such as order or payment notifications without building and maintaining templates or a dashboard step.
- Requirements
- Runs as a local process via npx from the sendableme-mcp npm package, so Node.js is needed. Requires a Sendable API key supplied in the SENDABLE_API_KEY environment variable; a free key covers 500 messages a month. Desktop client only.
Installation
In SourceWeft
- Open Sendable in the dashboard and add it to a workspace.
- 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.
Other MCP clients
Follow the launch instructions in the repository.
README
Sendable
One line, and your app knows how to talk to its users.
You describe what happened; Sendable writes the message and sends it. No templates to maintain, no dashboard step — your data is never rewritten, only the words around it.
That's a complete integration. Adding a new message type is a new string.
Get a free API key at sendable.me/keys — 500 messages a month, no card.

What's in this repo
Your data is never rewritten
The model that writes the copy never sees your values — only your field names. It
writes copy containing {{placeholders}}, and your values are substituted
afterwards, so a price, a date, or a reset link cannot be altered. A second model
checks every draft for claims your data doesn't support and refuses rather than
guess.
MCP
Add it to Claude Desktop or Cursor and send transactional email straight from the
editor. See mcp/ for the config block.

Score
50% 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.
- Reached in the last 30 days25 pts
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.
