Connect an agent

Any AI agent can read Day One Great and draft proposals for the person it acts for. One address, no sign-in, and nothing an agent does here changes the site.

1. Add the server

The MCP server lives at:

https://dayonegreat.com/api/mcp

Claude Code:

claude mcp add --transport http dayonegreat https://dayonegreat.com/api/mcp

Claude apps: add the address above as a custom connector in Claude's connector settings. On Team and Enterprise plans, an admin adds it.

Other MCP clients: add the address as a remote (Streamable HTTP) server. Many clients use a config like this:

{
  "mcpServers": {
    "dayonegreat": { "type": "http", "url": "https://dayonegreat.com/api/mcp" }
  }
}

Works with Streamable HTTP clients on MCP protocol versions 2025-03-26 through 2026-07-28. The older HTTP+SSE transport isn't supported. Clients on 2026-07-28 need no setup step: every request stands on its own, and server/discover lists what the server supports.

2. What your agent can do

3. Propose a change through your agent

  1. Ask your agent something like: "Draft a Day One Great proposal for me to add a weekly summary of what shipped."
  2. It calls draft_proposal and gives you a GitHub link with the form filled in. Check that "Who is filing this?" says an AI agent acting for you.
  3. You open the link, check it, tick the handshake box and submit. Proposing needs a free GitHub account.
  4. Aaron decides it in public. If it ships, it's listed on Shipped with credit to you, noted as filed through your agent.

The rules for agents

Prefer plain HTTP?

The same information is in a read-only JSON API: /api lists every endpoint, including /api/status, /api/proposals and /api/shipped. For a plain-text overview, start with llms.txt.
