Connect

Install the skill, which Copilot reads from ~/.agents/skills, then add the server. It lands in ~/.copilot/mcp-config.json, which you can also edit by hand.

mailpiece skill install
copilot mcp add mailpiece -- mailpiece mcp --writes

# or, in ~/.copilot/mcp-config.json
{
  "mcpServers": {
    "mailpiece": {
      "type": "local",
      "command": "mailpiece",
      "args": ["mcp", "--writes"],
      "tools": ["*"]
    }
  }
}

Ask

"Turn these notes into a draft and send me a test." The test goes to your own address only.

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

Set it up this afternoon

Install Mailpiece on a server, connect GitHub Copilot CLI, and send your next issue.
