What it can do

What can Kimi K3 do with Postemi?

Kimi K3 gets the same Postemi tools in every workspace it connects to. It writes; Postemi schedules and publishes.

Draft, schedule or publish

Kimi K3 creates a post as a draft, schedules it for a time you name, or publishes it right away. Ask for a draft when you want to check it first.

Preview per account

Before it creates anything, Kimi K3 can show what would go out on each account: the text, the media and the character count.

Reads your calendar

Kimi K3 sees what is already scheduled, in your time zone, so it can find a free slot or move a post.

Knows each platform's rules

Postemi tells Kimi K3 the character limit and the options of every connected account before it writes.

Images and video

Kimi K3 adds media from a link, or gives you an upload link for a file on your own computer.

Workspaces and client groups

If you manage several brands, Kimi K3 lists your workspaces and client groups and works in the one you pick.

The MCP server

What is the Postemi MCP?

MCP (Model Context Protocol) is an open standard that lets an AI agent use outside tools. Postemi runs a hosted MCP server at https://mcp.postemi.com/mcp. Kimi K3 connects to it, and from then on it can list your channels, read your calendar and create posts in your Postemi account.

The server runs on Postemi's side, so there is nothing to install for it. You sign in to Postemi in the browser, or use an MCP key, and that decides the workspace Kimi K3 works in. Your social accounts stay connected in Postemi itself: Kimi K3 never sees their passwords.

Postemi has no built-in AI writer, on purpose. Kimi K3 writes the posts, Postemi schedules and publishes them.

How Kimi K3 uses Postemi

Once Postemi is connected, Kimi K3 finds the tools by itself and calls them when you ask for a post.

  • Reads your connected accounts and each one's rules
  • Checks the calendar and your time zone before it picks a time
  • Can show a preview per account before it creates a post
  • Saves a draft, schedules, or publishes now, as you asked
  • Adds images and video from a link, or from an upload link you open
