Cast to Warpcast from Hermes Agent

Hermes Agent can publish and schedule Farcaster casts on Warpcast through Postiz. Once the Postiz skill is installed, you tell Hermes what to cast and which channel to use from Telegram, Discord, Slack, or the CLI. It resolves the Farcaster channel ID, attaches uploaded media, and schedules the cast for you.

What is Hermes Agent?

Hermes Agent is an open-source AI agent from Nous Research, released under the MIT license. It runs on your own machine or server, you talk to it from Telegram, Discord, Slack, WhatsApp, Signal, or the CLI, and it executes tools such as the Postiz skill to post to Warpcast and other channels. It works with Nous Portal, OpenRouter, OpenAI, or your own model endpoint.

💬

Talk to Hermes from Telegram, Discord, Slack, WhatsApp, Signal, email, or the terminal. Ask for a Warpcast post from whichever app you already have open.

⏰

Built-in Cron Scheduler

Create recurring jobs in plain language, such as weekdays at 9am. Hermes drafts and schedules Warpcast content through Postiz and reports back to your chat.

🔧

Open Source, Any Model

Hermes Agent is MIT licensed and self-hosted. Run it on Nous Portal, OpenRouter, OpenAI, or your own endpoint, and extend it with MCP servers or skills like Postiz.

How Postiz Works with Hermes Agent

Postiz ships as an agent skill in the agentskills.io SKILL.md format that Hermes Agent reads. The skill documents every Postiz CLI command, the credentials it needs, and the Warpcast settings, so Hermes knows how to list your channels, upload media, and create posts without any custom code.

✓Install the Postiz CLI (npm install -g postiz) and add the skill with npx skills add gitroomhq/postiz-agent
✓Hermes loads skills from ~/.hermes/skills and shows them with hermes skills list
✓Authenticate with POSTIZ_API_KEY, or run postiz auth:login for an OAuth device flow
✓Every Postiz command returns JSON, so Hermes can chain discovery, upload, and posting
✓Prefer MCP? Add https://mcp.postiz.com/mcp-oauth-dynamic under mcp_servers in ~/.hermes/config.yaml

Install Postiz

# Install the Postiz CLI and skill
npm install -g postiz
npx skills add gitroomhq/postiz-agent

# Authenticate: API key or OAuth device flow
export POSTIZ_API_KEY=your_api_key
# or: postiz auth:login

# Confirm Hermes can see the skill

Warpcast Posting with Hermes Agent

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

🧠

From Any Chat App

Telegram, Discord, Slack, WhatsApp, Signal

Hermes Agent

You: Post to Warpcast about our new
  feature launch, schedule for tomorrow
  at 9am

Hermes: I'll handle that! Let me:
  1. Find your Warpcast integration
  2. Compose your post content
  3. Schedule for tomorrow 9:00 AM

  Done! Post scheduled successfully.
  Post ID: abc-123

  "Check ~/content/warpcast for new posts.

You can ask Hermes Agent to create, schedule, cancel, and measure Warpcast posts in plain language. These are the kinds of requests it handles through Postiz.

Ask Hermes Agent

> Cast our launch update to the /dev channel on Warpcast tomorrow at 9am.

Hermes sets the Farcaster channel ID for /dev and schedules the cast via Postiz.

Ask Hermes Agent

> Post this screenshot to my Warpcast feed with a one-line caption, no channel.

Warpcast rules Hermes Agent has to follow

Postiz validates every Warpcast post before it is scheduled, so these limits and required settings decide whether a request succeeds.

▸Casts are short. Standard casts are limited to about 320 characters, so ask Hermes to keep it tight or split into a thread of replies.
▸Channels are targeted by Farcaster channel ID in the subreddit[].value.id field. Hermes resolves the ID from the channel name you give.
▸Leave the channel out to cast to your main feed.
▸Media must be uploaded with postiz upload before it can be attached to a cast.

Hermes Agent and Warpcast: frequently asked questions

Can Hermes Agent post to Warpcast?

Yes. With the Postiz skill installed, Hermes Agent creates and schedules Farcaster casts on Warpcast, either on your feed or in a specific channel, with optional images. You describe the cast in plain language from any chat Hermes is connected to and it runs the Postiz CLI commands for you.

How do I connect Warpcast to Hermes Agent?

Connect your Farcaster account in the Postiz dashboard, then install the Postiz skill in Hermes with npx skills add gitroomhq/postiz-agent and set POSTIZ_API_KEY. Hermes finds the Warpcast channel with postiz integrations:list. Your Farcaster signer stays in Postiz; Hermes only holds the Postiz key.

How does Hermes Agent cast to a specific Warpcast channel?

Warpcast channels are identified by a Farcaster channel ID. When you say "cast to /dev", Hermes fetches the channel list through Postiz, matches the name, and passes the ID in the channel setting. If you do not name a channel, the cast goes to your main feed.

Is there a character limit when Hermes Agent casts to Warpcast?

Yes. Standard Farcaster casts are limited to roughly 320 characters, which is shorter than most platforms. Ask Hermes to keep casts brief, or request a thread so the extra text goes into reply casts. Postiz reports a validation error if the cast is too long.

Can Hermes Agent cast to Warpcast on a schedule?

Yes. Hermes Agent has a built-in cron scheduler. Run hermes cron create "every friday 3pm" with a prompt such as "write a weekly recap and cast it to /founders via Postiz". Hermes runs the job unattended and sends a confirmation to Telegram, Discord, or whichever chat you use.
