Hermes Agent, the open-source self-improving agent from Nous Research, just shipped a built-in MCP Catalog , a curated, interactive store of pre-reviewed tool integrations you can install with a single keypress. If you've ever wanted your agent to manage GitHub issues, trigger n8n workflows, or query Linear tickets without writing a line of YAML, this is the feature that makes it trivial.

The problem it's solving

MCP (Model Context Protocol) is the emerging open standard that lets AI agents connect to external tool servers , think GitHub, databases, file systems, Stripe, and internal APIs , without the agent developer having to build native integrations from scratch. The protocol has been gaining momentum fast, but the setup experience has been rough: find a server, read its docs, figure out the right command and args, handle OAuth, manage credentials. Every integration was a manual config surgery job.

Hermes now ships a curated catalog of MCP servers that Nous staff has reviewed and merged. They're disabled by default , install only what you actually want. The catalog is surfaced through an interactive terminal picker, and the whole flow from "I want this tool" to "it's wired up and working" is a few keypresses.

How it works

The catalog is accessed via three commands:

hermes mcp              # interactive picker (default)
hermes mcp catalog      # plain-text list, scriptable
hermes mcp install n8n  # install a catalog entry by name

Hitting Enter on a row walks you through installing (including any required credentials), and lets you enable, disable, or uninstall. The picker shows each entry with a live status label ,
