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 LinkedIn and other channels. It works with Nous Portal, OpenRouter, OpenAI, or your own model endpoint.

🔧

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 LinkedIn 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

# From the terminal
hermes cron create "weekdays at 9am" \
  "Check ~/content/linkedin for new posts.
   Upload any media with postiz upload,
   then schedule each one to LinkedIn
   for noon today via Postiz. Move posted
   files to ~/content/published."

# Or from any chat with Hermes
/cron add "weekdays at 9am" "Schedule

What can you ask Hermes Agent to do on LinkedIn?

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

Ask Hermes Agent

> Write a LinkedIn post announcing our Series A, keep it under 1,500 characters, and schedule it on the company page for Thursday at 8am.

Hermes drafts the copy, finds your LinkedIn Page channel with postiz integrations:list, and schedules it there.

Ask Hermes Agent

> Post these four slides as a LinkedIn carousel called "2026 roadmap" on my personal profile.

Hermes uploads each image, sets post_as_images_carousel: true and carousel_name, and creates the post.

Ask Hermes Agent

> Share our latest blog post on LinkedIn with the cover image and a two-line summary tomorrow at 9am.

Hermes reads the article, writes the summary, attaches the uploaded cover image, and schedules it.

LinkedIn rules Hermes Agent has to follow

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

▸LinkedIn posts are limited to 3,000 characters. Ask Hermes to keep long updates within that or move the detail into a linked article.
▸Personal profiles and company pages are separate Postiz channels. Say which one you mean, or Hermes may ask before posting.
▸A carousel needs more than one uploaded image plus post_as_images_carousel: true. A single image publishes as a normal image post.
▸Every image must go through postiz upload first. External image URLs are rejected when the post is published.

Hermes Agent and LinkedIn: frequently asked questions

Can Hermes Agent post to LinkedIn?

Yes. Hermes Agent uses the Postiz skill to create, schedule, and delete LinkedIn posts on personal profiles and company pages. It can attach images, publish multi-image carousels with a name, and pull post analytics. You ask in plain language from any chat Hermes is connected to and it runs the Postiz commands.

How do I connect LinkedIn to Hermes Agent?

Connect your LinkedIn profile or LinkedIn Page in the Postiz dashboard, then install the Postiz skill in Hermes with npx skills add gitroomhq/postiz-agent and set POSTIZ_API_KEY. Hermes lists your LinkedIn channels with postiz integrations:list. Your LinkedIn login never leaves Postiz, and Hermes only holds the Postiz key.

Can Hermes Agent post to a LinkedIn company page?

Yes. LinkedIn Pages connect to Postiz as their own channel. When you ask Hermes to post "on the company page", it picks that channel's integration ID and schedules there. If you have several pages, name the page so Hermes does not have to guess which one you mean.

How does Hermes Agent create a LinkedIn carousel?

Ask for a carousel and provide two or more images. Hermes uploads each file with postiz upload, sets post_as_images_carousel to true, gives it a carousel_name, and creates the post. LinkedIn renders the images as a swipeable document, which is why a single image cannot become a carousel.

Can Hermes Agent publish LinkedIn posts on a recurring schedule?

Yes. Use Hermes Agent's cron scheduler: hermes cron create "every monday 8am" with a prompt that tells it to draft and schedule that week's LinkedIn post through Postiz. Hermes runs the job unattended and sends a summary to Telegram, Discord, Slack, or whichever chat you use.
