Hermes Agent Quickstart: Install and Run Your First Chat
The fastest path to a working Hermes Agent is short: install it, choose one provider, run one chat, and confirm the session was recorded. Everything else, from messaging channels to tool servers, is an addition to a runtime that already works. This guide keeps that first pass deliberately small so that when something breaks later you know what changed.
- 01
Install with the desktop installer or the CLI
The desktop installer for macOS and Windows is the shortest path and handles the runtime for you. Without it, install from the command line on Linux, macOS, or WSL2 and add the command to your path.
- 02
Choose one provider and add its key
Pick a single provider, such as Anthropic, OpenAI, Google, or OpenRouter, and store the key where the agent reads its configuration. One working provider is the goal, not five configured ones.
- 03
Run your first chat
Start the agent, send one message, and read the reply. This confirms installation and provider access in one action.
- 04
Verify the session was recorded
Confirm the conversation appears in the agent's session list and that memory files were created. A reply that was never stored will not survive a restart.
- 05
Add the next layer only now
Connect a messaging channel, an MCP server, or scheduled runs. Add one at a time so a failure has exactly one candidate cause.
Four-step path
How do you install Hermes Agent and run a first chat?
Four steps, each with an observable result. Stop and fix the step you are on before moving to the next.
- Step 01
Install with the desktop installer or the CLI
The desktop installer for macOS and Windows is the shortest path and handles the runtime for you. Without it, install from the command line on Linux, macOS, or WSL2 and add the command to your path.

- Step 04

- Step 05
Add the next layer only now
Connect a messaging channel, an MCP server, or scheduled runs. Add one at a time so a failure has exactly one candidate cause.
What do you need before you start?
A supported machine, a model provider key, and about fifteen minutes. Nothing else is required for a first chat.
- macOS, Windows, Linux, or WSL2. The desktop installer covers macOS and Windows.
- One provider API key, or a local model if data cannot leave your machine.
- Terminal access if you install without the desktop installer.
Which provider should you choose first?
Whichever one you already have a key for. Provider choice is reversible, and routing and fallbacks can be added once the first chat works.
- Anthropic, OpenAI, and Google are the common starting points.
- OpenRouter gives one key across many models, which suits experimentation.
- A local model keeps everything on your hardware at the cost of capability.
How do you know the installation is real?
You get a reply to a real message and the session is retrievable afterwards. Anything short of both is an unverified installation.
- The reply arrives without error output in the terminal.
- The session is listed and can be reopened.
- Memory files exist on disk after the first exchange.
- A restart does not lose the conversation.
What usually goes wrong in the first hour?
Missing keys, a provider key stored where the agent does not read it, and a path problem that makes the command unavailable in a new shell.
- The key is set in one shell but not in the environment the agent starts with.
- The install succeeded but the command is not on the path yet.
- A provider quota or billing issue looks like a model error.
What comes after the first chat?
One messaging channel, then the tool servers the work requires, then scheduled runs if the job is repetitive.
Which primary sources support this page?
Product behavior is checked against the current deployment flow. These external links provide the upstream project or channel documentation used for setup details.

Frequently asked questions
How long does a first Hermes Agent setup take?
About fifteen minutes to a first reply if you already have a provider key. Connecting a channel and tool servers is where the time actually goes.
Do I need the desktop installer?
No. It is the shortest path on macOS and Windows, but a command-line install works on Linux, macOS, and WSL2 and gives you more control over versions.
How do I confirm the agent actually works?
Send a real message, read the reply, and then reopen the session. Both a reply and a retrievable session are needed for a verified installation.
Should I connect a messaging channel immediately?
Not before the local chat works. Debugging a channel and a runtime at the same time doubles the number of possible causes.
Key takeaways
- The fastest path to a working Hermes Agent is short: install it, choose one provider, run one chat, and confirm the session was recorded. Everything else, from messaging channels to tool servers, is an addition to a runtime that already works. This guide keeps that first pass deliberately small so that when something breaks later you know what changed.
- Start with one model, one channel, and one controlled test conversation.
- Use managed hosting when deployment speed matters more than operating the server yourself.
