Post to Warpcast from Perplexity Computer

Perplexity Computer can schedule and publish casts to Warpcast, the Farcaster client, through Postiz. Connect Postiz as a custom MCP connector in Perplexity or install the Postiz CLI skill, then describe the cast and name a channel if you want one. Computer keeps the cast short, attaches media, sets the Farcaster channel id, and schedules it.

Setup Guide

Please make sure there is always a human in the loop.

Perplexity Computer is Perplexity's agentic workspace: you give it a goal, it breaks the goal into subtasks, orchestrates 20+ AI models, uses connectors and skills, and delivers a finished result. It is not the Perplexity search engine and not the Comet browser. It is available on Perplexity Pro and Max plans.

🧩

Task Decomposition

Perplexity Computer breaks complex social media campaigns into subtasks and handles each one with specialized sub-agents for maximum quality.

🔄

Multi-Model

Spawns sub-agents across 20+ different AI models, picking the best model for each subtask — content writing, image generation, scheduling, and more.

🎯

End-to-End Delivery

Schedule recurring tasks with cron jobs. Perplexity Computer can publish your casts on a schedule without you having to ask each time.

How Postiz Works with Perplexity Computer

Perplexity Computer discovers Postiz commands through its tool integration system. It can decompose a social media campaign into subtasks and use Postiz to execute each one.

✓Add the Postiz MCP connector in Perplexity (OAuth), or install the Postiz CLI skill
✓Every Computer task can call the Postiz tools once the connector is added
✓Tasks are decomposed across specialized sub-agents
✓Each sub-agent picks the best model for its subtask
✓Results are delivered end-to-end with verification

Connect Postiz

# Perplexity > Settings > Connectors
# + Custom connector > Remote
Name:            Postiz
MCP server URL:  https://mcp.postiz.com/mcp-oauth-dynamic
Authentication:  OAuth

# Or, the CLI skill:
npx skills add gitroomhq/postiz-agent
export POSTIZ_API_KEY=your_api_key

Warpcast Posting with Perplexity Computer

Message Perplexity Computer from any platform — it reads the Postiz skill, discovers your Warpcast integration, and handles the entire casting workflow autonomously.

🌐

From the Computer Workspace or Slack

Delegate the goal, Computer runs the steps

Give Perplexity Computer the goal in the Computer workspace or from Computer in Slack. It uses the Postiz connector to find your Warpcast account, writes a short cast, sets the channel, and publishes it to Farcaster while you get on with your day.

Also Works with Claude Code

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.

Claude Code

by Anthropic

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.

Claude Code

  dev and crypto channels on Farcaster

Claude: Done! Scheduled on Warpcast for
  tomorrow at 9:00 AM.

Warpcast + Other Platforms

Schedule the same content to Warpcast and other platforms in a single request. Each platform gets its own settings.

Example

What can you ask Perplexity Computer to do on Warpcast?

You can ask Perplexity Computer for anything Postiz can do on Warpcast: draft, schedule, publish, attach media, and set Warpcast-specific options. These are prompts people actually type.

You say

> Cast this build update in /dev with the screenshot
  and keep it under 320 characters

Computer writes a compact cast, uploads the image through Postiz, and sets the channel id to dev.

You say

> Post the same announcement on Warpcast and X, but
  make the cast shorter and skip the hashtags

Computer creates two Postiz posts, one per channel, with the cast trimmed for Farcaster.

You say

> Every morning at 9am cast one insight from our
  research notes to my Warpcast feed

Computer proposes a Scheduled Task and creates a daily cast through Postiz without a channel target.

Warpcast rules Perplexity Computer has to respect

Warpcast enforces a few rules on every post. Postiz exposes them as settings, and Perplexity Computer applies them, but knowing them helps you phrase the request.

✓Casts are short form: keep a standard cast to about 320 characters.
✓The channel target lives in subreddit[].value.id and takes the Farcaster channel id (for example founders), without the slash.
✓Leave the channel out to cast to your main feed.
✓Media is uploaded through Postiz before it is attached to the cast.

Perplexity Computer and Warpcast: frequently asked questions

How do I post a cast to Warpcast from Perplexity Computer?

Add Postiz as a custom remote connector in Perplexity settings with the MCP URL https://mcp.postiz.com/mcp-oauth-dynamic and OAuth, and connect your Warpcast account in Postiz. Then ask Computer to cast. It writes the text, sets an optional Farcaster channel, and schedules it through Postiz.

Can Perplexity Computer cast into a specific Farcaster channel?

Yes. Name the channel, for example /founders, and Computer fills the channel id in the Postiz Warpcast settings, so the cast appears in that channel. Leave the channel out and it posts to your main feed. It can also target different channels in the same request.

How long can a cast be when Computer posts to Warpcast?

Farcaster casts are short form, about 320 characters for a standard cast, so Computer writes compact copy and drops hashtags that do not add value. If you hand it a long announcement, it summarizes for Warpcast and can post the full version on X or LinkedIn at the same time.

Do I need a Postiz API key to cast from Computer?

Not with the MCP connector. Perplexity signs in to Postiz over OAuth with your own account, so Computer only uses the Warpcast account you connected. The CLI skill path (npx skills add gitroomhq/postiz-agent) is the alternative and reads POSTIZ_API_KEY from Computer's sandbox environment.

Is Warpcast the same as Farcaster?

Farcaster is the decentralized social protocol; Warpcast is the most widely used client for it. Postiz publishes to Farcaster through your Warpcast account, so a cast created by Computer appears in Warpcast and in any other Farcaster client that reads the same protocol.
