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 Dev.to 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 Dev.to 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
