Integrate with Hermes Agent ​

Hermes Agent is an open-source autonomous AI agent for automated tasks and terminal interaction.

I. Prerequisites ​

Before using Hermes Agent, prepare the following.

1. Install Hermes Agent ​

Supported on Linux, macOS, and WSL2 (Windows). Windows users must first install WSL2, then run the commands inside WSL2.

Run the following command in your terminal to install Hermes Agent.

bash
curl -fsSL https://raw.githubusercontent.com/NousResearch/hermes-agent/main/scripts/install.sh | bash

Reload your terminal environment.

bash
source ~/.bashrc   # or source ~/.zshrc

Run the following command to verify the installation (a version number means success).

bash
hermes --version

After installation, the following interface will appear:

hermes-2

2. Get a LongCat API Key ​

First, obtain your API Key from the LongCat Platform, and confirm on the Usage page that your account has sufficient token quota.

The LongCat API platform currently provides the following models:

Model NameAPI FormatDescription
LongCat-2.0OpenAI/AnthropicHigh-performance agentic model

II. Configure the LongCat API ​

Hermes Agent connects to LongCat through a custom provider. model.provider must be set to custom.

Option A: Quick setup via terminal commands ​

bash
hermes config set model.provider custom
hermes config set model.base_url https://api.longcat.chat/openai
hermes config set model.api_key <Your LongCat API Key>
hermes config set model.default LongCat-2.0

You can review the result in ~/.hermes/config.yaml.

Option B: Edit the config file manually ​

Edit ~/.hermes/config.yaml:

yaml
model:
  provider: custom
  base_url: https://api.longcat.chat/openai
  api_key: <Your LongCat API Key>
  default: LongCat-2.0

Get <Your LongCat API Key> from the LongCat Platform.

Verify the configuration ​

bash
hermes doctor

III. Using Hermes Agent ​

Once configured, open a new terminal window and run one of the following commands to launch Hermes Agent:

bash
hermes            # Classic CLI mode
hermes --tui      # Modern TUI mode

If the conversation UI opens normally, you're ready to use Hermes Agent + LongCat.
