Mailpiece with Zed

A fast editor, and a newsletter it can write to.

Write your newsletter from Zed: its agent turns your notes into an issue and drafts it in Mailpiece.

Connect

Run mailpiece skill install, which puts the skill in ~/.agents/skills, where Zed's agent finds it. Then run zed: open settings file and add the server under context_servers, or use Settings › AI › MCP Servers › Add Server › Add Local Server. A green dot next to it means it's running.

mailpiece skill install

{
  "context_servers": {
    "mailpiece": {
      "command": "mailpiece",
      "args": ["mcp", "--writes"],
      "env": {}
    }
  }
}

Ask

In the Agent Panel: "Turn these notes into a draft post and send me a test."

Sending to the whole list can't be undone, so read what Zed is about to do before you let it.

Set it up this afternoon

Install Mailpiece on a server, connect Zed, and send your next issue.
