Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

n8n-nodes-hermes-agent

An n8n community node for connecting workflows to a self-hosted Hermes Agent API server.

Features

  • OpenAI-compatible chat completions and Responses API
  • Stateful conversations using previous_response_id or a named conversation
  • Long-running Hermes runs, polling, stopping, and approval decisions
  • Jobs and sessions management
  • Models, capabilities, skills, toolsets, and health discovery
  • Custom API requests for endpoints added by future Hermes releases
  • Can be used as an n8n AI tool

Streaming endpoints are intentionally invoked in non-streaming/polling form because normal n8n node executions produce completed items rather than an open SSE stream.

Install

Install n8n-nodes-hermes-agent from Settings → Community Nodes, or install it into a self-hosted n8n installation with npm.

For local development:

npm install
npm run dev

Configure Hermes

Add the following to the Hermes profile's .env, then start the gateway:

API_SERVER_ENABLED=true
API_SERVER_KEY=replace-with-a-strong-secret
hermes gateway

Create an Hermes Agent API credential in n8n with:

  • Base URL: for example http://host.docker.internal:8642 when n8n runs in Docker and Hermes runs on the host
  • API Key: the value of API_SERVER_KEY

Do not use localhost from an n8n container unless Hermes runs in the same container. The API grants access to Hermes' full toolset, so expose it only on trusted networks and protect the key.

Development

npm run lint
npm run build
