Post to Warpcast from Grok Bot
Grok Bot can post casts to Warpcast on the Farcaster protocol through the Postiz plugin. Add the plugin to a Bot, store your Postiz API key as a secret, and say what to cast. The Bot targets a Farcaster channel if you name one, keeps the cast within the length limit, schedules it in Postiz, and can cast daily on a routine.
Please make sure there is always a human in the loop.

Grok Bot is the always-on AI teammate product from xAI and Cursor. You create named Bots, give each one a job, and they work 24/7 on their own persistent cloud computer — with a browser, a filesystem, and a terminal — pinging you only when they need approval.
Grok Bot is not the Grok chatbot. Grok is the assistant you chat with on X and grok.com. Grok Bot is a separate app for delegating real, multi-step work — like running your Warpcast presence with Postiz.
Own Cloud Computer
Every Bot gets a persistent cloud machine with a terminal. Postiz runs there, so your Warpcast posts go out even when your laptop is closed.
Routines
Turn any task into a routine that runs on a schedule. Your Bot drafts, schedules, and reports on Warpcast content without being asked twice.
Approvals Built In
Bots ask before changing external systems. Review the Warpcast posts your Bot prepared in Postiz, approve, and it publishes.
How Postiz Works with Grok Bot
Postiz is listed on the Grok Bot plugin marketplace. Add it to a Bot and the Postiz skill, CLI, and command reference are installed on its cloud computer — the Bot can then manage your Warpcast workflow on its own.
- ✓Type /add-plugin postiz in a Bot chat, or add it from the Plugins sidebar
- ✓Store your POSTIZ_API_KEY as a Bot secret when prompted
- ✓The Bot reads the bundled SKILL.md and learns every Postiz command
- ✓Works in every Bot on your shared workspace, on desktop and iPhone
- ✓Approvals keep a human in the loop before anything is published

All Postiz commands are ready.How Grok Bot runs Warpcast on a routine
Your Bot reads the Postiz skill, discovers your Warpcast integration, and handles the entire posting workflow — from content creation to scheduling — on its own cloud computer.
Message Your Bot
Desktop, iPhone, or a group chat
Send a message to your Bot from the desktop app or your iPhone. It runs on its own cloud computer, so it picks up your message, discovers your Warpcast account via Postiz, uploads your media, and schedules the post — then asks you to approve before it goes live.

Postiz works with any AI agent that can run commands or call MCP tools — you ask, the agent does the work. That includes Anthropic's Claude Code. See the Claude Code guide for Warpcast, the guide for any AI agent, or connect over the Postiz MCP server.

Claude reads the Postiz skill so it knows what it can do, then autonomously discovers your Warpcast integration, composes your cast with optional channel targeting, and publishes it to Farcaster.

Grok Bot: Routine saved: daily-warpcast.Warpcast rules Grok Bot follows
Grok Bot reads the Warpcast rules from postiz integrations:settings before scheduling. These are the ones that most often change what gets published.
- ✓Farcaster casts are limited to 320 bytes. Grok Bot keeps casts short or asks to trim them.
- ✓Channel targeting is optional. When you name a channel, the Bot passes its Farcaster channel ID in the subreddit array, which Postiz reuses for channels.
- ✓Media must be uploaded through postiz upload first; the Bot cannot attach raw paths or external URLs.
- ✓Your Warpcast account is connected in Postiz once. Grok Bot only needs the Postiz API key, never your Farcaster signer.
Grok Bot and Warpcast: frequently asked questions
How do I cast to Warpcast from Grok Bot?
Add the Postiz plugin with /add-plugin postiz and store your POSTIZ_API_KEY as a Bot secret. Connect Warpcast in Postiz, then tell the Bot what to cast. It keeps the text within Farcaster's length limit, targets a channel if you name one, and schedules through Postiz. You approve first.
Can Grok Bot cast into a specific Farcaster channel?
Yes. Name the channel, such as /dev or /design, and the Bot fetches channel IDs with postiz integrations:settings and sets the target. Postiz stores Farcaster channels in the same field it uses for Reddit subreddits, so the settings reference shows it as subreddit.
How long can a cast be when Grok Bot posts it?
Farcaster limits casts to 320 bytes, roughly a short tweet. Grok Bot checks the length before scheduling and either trims the text or asks you which part to cut. For longer updates, cast a summary with a link to the full post elsewhere.
Does Grok Bot need my Farcaster signer or wallet?
No. You connect Warpcast to Postiz once, and Postiz holds the authorization. Grok Bot only uses your Postiz API key, stored as a Bot secret, and can only cast from accounts already connected in your Postiz workspace.
Can Grok Bot cast on a daily routine?
Yes. Save a routine such as "every day at 9am, cast one note from ~/content/farcaster.md". The Bot runs it from its own cloud computer, schedules through Postiz, and reports back. Approvals keep a human in the loop before anything is cast.
