01What the Hermes MCP Catalog Is and How It Works

Hermes MCP catalog is a free update from Hermes agent that lets you connect your AI agent to external tools with one click. Instead of editing config files, hunting for API keys, and spending 30 minutes per tool, you now open the catalog, pick a tool, and install it in about 30 seconds. The catalog only contains MCPs approved by the Hermes team, so you know they are safe and work smoothly.

This update makes it possible for non-technical users to link tools like NA10, Linear, and GitHub to Hermes. The catalog handles the install command, the environment variables, and the OAuth login for you. You no longer need to guess commands or manually restart Hermes after a setup.

The Goldie MCP hub framework mentioned in the episode layers this catalog into a dashboard that shows all installed MCPs and workflows in one place. This makes managing your tools even easier than using the terminal alone.

02Main Features of the MCP Catalog Update

  • One-click install: You pick a tool from the catalog and Hermes installs it automatically. No editing config files or copying commands.
  • Curated approval: Only MCPs reviewed by the Hermes team are in the catalog. This stops you from installing broken or unsafe servers.
  • Auto-discover tools: After installing, Hermes can list every tool you have set up. This is called the probe function and helps you verify everything is ready to use.
  • Environment variable handling: API keys and OAuth tokens are written into the local environment automatically. You do not need to manually add them.
  • Two install paths: You can use the terminal command hermes MCP install or build a visual dashboard (an agent operating system) for point-and-click installation.

03How to Set Up the Hermes MCP Catalog

  1. Make sure you have Hermes agent installed and running. The catalog is part of the free update, no extra cost.
  2. Open your terminal inside Hermes. You can also use an agent operating system dashboard if you have one set up.
  3. Run the command: hermes MCP install. This opens the MCP catalog in your terminal.
  4. Browse the list of approved MCPs. Currently the catalog includes NA10, Linear, and GitHub. More are coming.
  5. Select the tool you want to connect. For example, type hermes MCP install NA10 and press enter.
  6. Enter your API key when prompted. The catalog shows you exactly where to get the key.
  7. Let the install finish. Hermes handles the config file, environment setup, and OAuth login automatically.
  8. Verify the install by running the probe command to list all tools now available to your agent.

04How to Use the MCP Catalog in Your Workflows

Once installed, each MCP acts like a new service that Hermes can control. For example, if you install the NA10 MCP, you can ask Hermes to build workflows inside NA10, automate videos, or create infographics. The episode shows that the reason Julian can control NotebookLM and automate podcasts is because an MCP connects Hermes to that tool.

To start using a connected tool, simply give your agent a command that involves that service. Hermes automatically calls the MCP server you have set up. You do not need to mention the MCP by name—the agent discovers the tools and uses them when needed.

Inside the agent operating system, you can see all installed MCPs and the workflows you have built. For example, the episode shows an SEO workflow and an AI video agent set up inside a dashboard. You can switch between custom MCPs and pre-installed ones with a simple UI that replaces the terminal.

05Results and Comparisons Shown in the Episode

The episode directly compares the old way of setting up MCPs with the new catalog method. Old way: Open the MCP server's GitHub page, copy the install command, hand-edit the config file, get API keys, follow the OAuth flow, restart Hermes, test, debug, and repeat. This takes around 30 minutes per tool. If you need to disable a tool, you go through the whole process again.

New way with the catalog: Open the catalog via terminal or dashboard, pick the tool, enter the API key, and install. This takes about 30 seconds per tool. No config editing, no terminal commands to type, no restart needed.

The episode also notes that the catalog only has a few tools so far (NA10, Linear, GitHub), but the quality is high because they have been vetted. Julian says the catalog will grow with more entries over time.

06Tips, Limits, and Mistakes to Avoid

  • Install at least one MCP right away. The episode stresses that you should watch the tutorial and install at least one tool. Your Hermes agent will become much more powerful than someone who skips this update.
  • Do not skip the API key step. Even though the catalog automates most of the setup, you still need to provide your API key for each tool. The catalog tells you where to get it.
  • Understand the current catalog limits. Right now the catalog only includes NA10, Linear, and GitHub. If you need a different tool, you have to add it as a custom MCP through the manual method.
  • Do not assume Hermes can do everything without MCPs. Hermes works great on its own, but when you want to connect it to an outside service like GitHub or NA10, an MCP is required. The catalog makes that connection painless.
  • Custom MCPs are still an option. If a tool is not in the approved catalog, you can add it as a custom MCP using the dashboard or terminal.

07Who the Hermes MCP Catalog Is For and Why It Matters

The MCP catalog is designed for anyone who uses Hermes agent and wants to connect it to other tools without technical hassle. It is especially useful for non-developers who previously found MCPs too complex. If you can pick a row in a list and click install, you can use this catalog.

This update matters because it removes the biggest barrier to using MCPs: the manual configuration time. Instead of spending 30 minutes per tool, you spend 30 seconds. That means you can connect Hermes to multiple services and let the agent orchestrate your entire tool stack from one place.

Julian also points out that you can create an MCP for Hermes itself and connect it to other AI agents like Claude. This makes the Hermes MCP catalog a gateway for building multi-agent systems where different AI tools control each other. The catalog is free, Hermes is free, and you can build a dashboard for yourself without paying anything.
