Overview

AI-generated overview

Lets an assistant send and receive private on-chain messages through SealedMail on the Sui blockchain, without a browser wallet.

What you can do
This local MCP server connects an assistant to SealedMail, a private messaging service on the Sui blockchain. It exposes tools for sending and receiving on-chain private messages, so an assistant can compose and dispatch messages and read incoming ones on the user's behalf. It runs as a local process over stdio and does not require a browser wallet extension.
When to use it
Use it when you want an assistant to handle private on-chain messaging on Sui, for example sending or checking SealedMail messages during an agent workflow. It is not useful if you do not already use SealedMail or hold a Sui wallet.
Requirements
Runs locally as an npm package (npx sealedmail-mcp) over stdio, so Node.js is needed. It requires the environment variable SEALEDMAIL_PRIVATE_KEY, a Sui wallet private key in suiprivkey1... format exported with sui keytool export. Desktop only; no browser or web execution.
Before you install
The server needs SEALEDMAIL_PRIVATE_KEY, a Sui wallet private key that controls on-chain funds and assets; anyone who obtains it can act on that wallet. Sending messages writes to the blockchain and may cost gas, so transactions can spend money. Treat the key as highly sensitive and consider a dedicated wallet.

Installation

In SourceWeft

  1. Open Sealedmail 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.

Other MCP clients

Follow the launch instructions in the repository.
