Schedule Social Media Posts with Kimi K3
- No plugin needed: paste one prompt into Kimi Code CLI
- Kimi adds the Postiz MCP server itself, sign in once
- Draft, schedule and publish posts to 30+ platforms
Postiz is the agentic social media scheduling platform that Kimi K3 drives through the Postiz MCP server. Please make sure there is always a human in the loop. Last updated: September 2026. Looking for another open-weight agent? See DeepSeek, Hermes Agent, or the full agent list.
How do I connect Postiz to Kimi K3?
Kimi Code CLI is an MCP client and a skills host, so it can set itself up. Paste the prompt below and Kimi writes the Postiz server into its own config. You sign in once with OAuth. No API key, no manifest, no marketplace.
Paste this into Kimi Code
Kimi adds the Postiz MCP server to ~/.kimi-code/mcp.json itself. Full toolset, including image and video generation. OAuth sign-in.
Connect me to Postiz so you can schedule social media posts.
1. Add an MCP server named "postiz" with the URL
https://mcp.postiz.com/mcp-oauth-dynamic
to my Kimi Code MCP config (~/.kimi-code/mcp.json).
2. Tell me when to run /mcp-config login postiz so I can
sign in to Postiz in the browser.
3. Then list my connected channels.No API key needed. Run /mcp-config login postiz when Kimi asks and approve access in the browser. Want uploads from disk? Ask Kimi to install the postiz-agent skill with the second prompt below. Details on the Postiz MCP page.
Ask Kimi to post for you
Once connected, Kimi calls the Postiz tools from the terminal. Posts publish at the scheduled time even after you close kimi.
Schedule a post to X and LinkedIn for tomorrow at 9am announcing our new feature. Keep it short and upbeat.
Found your X and LinkedIn channels and scheduled both posts for 09:00 tomorrow. Want me to generate an image for them?
via Postiz
Also try
- 1Install Kimi Code CLI (curl -fsSL https://code.kimi.com/kimi-code/install.sh | bash), start kimi and run /login
- 2Paste the setup prompt. Kimi writes the postiz server into ~/.kimi-code/mcp.json
- 3Run /mcp-config login postiz and approve access to Postiz in the browser
- 4Tell Kimi which channels, what to say and when. It schedules the post through Postiz
Option 2: Ask Kimi to install the Postiz skill (uploads from disk)
The skills CLI supports Kimi Code as a target, so Kimi can install the Postiz skill into ~/.agents/skills and drive the postiz command. Use this when you want Kimi to attach images or videos from your project folder, or to write scripts that post on a timer. It works alongside Option 1.
Install the Postiz skill so you can post from the terminal:
1. Run: npx skills add gitroomhq/postiz-agent -a kimi-code-cli
2. Run: npm install -g postiz
3. Tell me to run postiz auth:login, then confirm you can
run postiz integrations:list.npx skills add gitroomhq/postiz-agent -a kimi-code-cli
npm install -g postiz
postiz auth:login # or export POSTIZ_API_KEY=...
postiz integrations:list # JSON list of your channelsThe same MCP link works in any MCP-capable assistant. See the Postiz MCP server page for Claude, ChatGPT, Gemini CLI, and others.
MCP server vs Postiz skill in Kimi Code: what is the difference?
Both reach the same Postiz account. The MCP server gives Kimi the full toolset including media generation; the skill gives it the postiz CLI, which is what uploads files from your disk and suits automation.
| Capability | Postiz MCP server | Postiz skill + CLI |
|---|---|---|
| How Kimi gets it | You ask Kimi (or run /mcp-config) to add the server URL | You ask Kimi to run npx skills add gitroomhq/postiz-agent -a kimi-code-cli |
| Where it lives | ~/.kimi-code/mcp.json (or .kimi-code/mcp.json in a project) | ~/.agents/skills/ (or .agents/skills/ in a project) plus the postiz CLI |
| Sign-in | OAuth in the browser via /mcp-config login postiz | postiz auth:login device flow, or POSTIZ_API_KEY |
| List channels, platform rules, analytics | Yes | Yes, through postiz integrations:list and integrations:settings |
| Draft, schedule, and publish posts | Yes | Yes |
| Generate images and videos, clip long videos | Yes, through the MCP tools | No, the skill focuses on posting and uploads |
| Attach local files from disk | No, media has to come from a URL or a generation tool | Yes, the CLI uploads images, videos, audio, and documents |
| Every command returns JSON | Tool results | Yes, which suits scripts and cron jobs |
| Best for | Chatting with Kimi K3 and creating media in the same request | Posting files from your project and automation |
Recommendation: start with the MCP server. Add the skill when you want Kimi to post files from your project or run on a schedule.
What can Kimi K3 do with Postiz?
Kimi K3 is built for long, multi-step agent work, and social media is a long, multi-step job. Once connected, Kimi handles the whole loop from draft to scheduled post.
Set It Up by Asking
No plugin to find. Paste one prompt and Kimi writes the Postiz server into its own MCP config, then tells you when to sign in.
30+ Platforms
Post to X, LinkedIn, Reddit, Instagram, YouTube, TikTok, and more from one prompt. Platform rules are read from Postiz, not guessed.
OAuth, No API Key
/mcp-config login postiz opens the browser once. Kimi only ever reaches the channels already connected to your Postiz account.
Plan & Schedule Ahead
Ask Kimi to plan a week of posts and pick the times. Postiz publishes them on schedule after you close the terminal.
Generate Images & Videos
Through the MCP tools Kimi can generate images and videos in Postiz, clip long videos into shorts, and attach them to posts in one request.
Uploads from Disk
Add the Postiz skill and Kimi runs the postiz CLI to attach the screenshot or demo video sitting in your project folder.
How does Kimi Code talk to Postiz?
Kimi Code CLI acts as an MCP client: it connects to external tool servers and exposes their tools to the agent alongside its built-in ones. The Postiz MCP server is one of those servers. It exposes your Postiz account as tools such as listing channels, reading platform rules, scheduling posts, and generating media.
What happens after the prompt
- Kimi writes the postiz entry into ~/.kimi-code/mcp.json
- You run /mcp-config login postiz and approve access in the browser
- Kimi discovers the Postiz tools and your connected channels
- It composes posts in the right format for each platform
- It schedules, drafts, or publishes, exactly as you asked
- With the skill, it also runs the postiz CLI for local uploads
MCP server (Option 1):
~/.kimi-code/mcp.json -> postiz
/mcp-config login postiz
# - list connected accounts
# - schedule / publish a post
# - platform settings & analytics
# - generate image / video, clipping
Skill + CLI (Option 2):
~/.agents/skills/postiz/SKILL.md
postiz auth:login
# - upload files from disk
# - JSON output for scriptsRead more on the Postiz MCP server page, in the MCP docs, or in the Kimi Code repository.
What can I ask Kimi to post?
Anything you would ask a teammate. Name the channels, the timing, and the tone. Kimi reads the platform rules from Postiz and handles the rest.
Ship a launch post
Schedule a post to X and LinkedIn for tomorrow at 9am announcing our new feature. Keep it short and upbeat.
Turn the README into a thread
Read README.md and write a launch thread for X plus a longer LinkedIn post. Space them across this week.
Post a recording from disk
Post ./demo/recording.mp4 to YouTube and TikTok on Friday at 11am with a caption from CHANGELOG.md.
Plan a whole week
Plan a week of posts about our launch and space them out across X, LinkedIn and Instagram at the best times.

Kimi K3 vs Kimi Code CLI vs the Kimi app: which one is this?
Moonshot AI uses the Kimi name for the model, the terminal agent, and the chat app. Postiz connects to the agent. Here is how the three fit together.
Kimi K3 (the model)
Moonshot AI's open-weight frontier model, built for long coding, reasoning, and agent workflows. It is what does the thinking when Kimi Code drafts and schedules your posts.
Kimi Code CLI (this page)
The open-source terminal agent that runs Kimi K3, edits files, runs commands, and connects to MCP servers and skills. This is where you paste the setup prompt and where Postiz plugs in.
Kimi app (kimi.com)
The chat assistant on the web and mobile. It has no Postiz connector and no custom MCP option, so it cannot post for you. Write copy there if you like, then let Kimi Code or Postiz schedule it.
Still on the legacy Python Kimi CLI? Its config lives at ~/.kimi instead of ~/.kimi-code; run kimi migrate to move to Kimi Code CLI. Using Claude, ChatGPT, Gemini, or another agent? See the Postiz Agent page.
Pricing, security, and troubleshooting
How much does it cost?
Connecting Kimi has no separate charge. Postiz starts with a 7-day free trial, then plans run from $29 per month for 5 channels to $99 per month for 100 channels. Every plan includes AI video and clipping minutes, and AI images are included from the Team plan up.
How is access secured?
Kimi connects through OAuth: /mcp-config login postiz opens the browser, you sign in to Postiz and approve access, and no password or API key goes into a prompt. Kimi only reaches the channels already connected in Postiz. Delete the postiz entry from mcp.json to disconnect.
Something not working?
- No Postiz tools: run /mcp. If postiz is missing, check ~/.kimi-code/mcp.json (legacy builds read ~/.kimi/mcp.json) and restart kimi.
- Auth error: run /mcp-config login postiz and finish the Postiz approval in the browser.
- Kimi can't attach a local file: install the skill with Option 2 so it can run the postiz CLI.
- Kimi can't see any channels: connect your social accounts in Postiz first, then ask again.
