Hermes Registry

Hermes Registry — Docs

The Hermes registry is a community catalog of installable extensions for the Hermes agent and the Hermes One desktop app — skills, MCP servers, agents, workflows, and model catalogs. This site (the web/ app) is its frontend, in the spirit of npmjs.com: browse, search, and open a detail page for every entry, backed by a public read API and per-entry install counters.

Start here

  • Getting started — install Hermes One, get the hermesone CLI, and add your first entry.
  • The registry — what's in it, the entry types, and how the catalog (index.json) is built.
  • CLI reference — every hermesone command, including add.
  • Publishing an entry — contribute a skill, MCP, agent, or workflow.
  • API reference — the public read API and the download endpoint.

Everything in the registry is free and open. The catalog is the single source of truth on GitHub; this site ingests it into Postgres so it can record installs and serve fast search.
