+title: AI agents
+weight: 5
+---
+
+Lima is useful for running AI agents inside a VM, so as to prevent agents
+from directly reading, writing, or executing the host files.
+
+For running AI agents, it is highly recommended to only mount your project directory (current directory)
+into the VM:
+
+{{< tabpane text=true >}}
+{{% tab header="Lima v2.0+" %}}
+```bash
+limactl start --mount-only .:w
+```
+
+Drop `:w` for read-only mode.
+{{% /tab %}}
+{{% tab header="Lima v1.x" %}}
+```bash
+limactl start --set ".mounts=[{\"location\":\"$(pwd)\", \"writable\":true}]"
+```
+
+Set `writable` to `false` for read-only mode.
+{{% /tab %}}
+{{< /tabpane >}}
+
+<!--
+AI agents are sorted alphabetically.
+
+Node.js is installed via snap, not apt, as AI agents often require a very recent release of Node.js.
+-->
+{{< tabpane text=true >}}
+{{% tab header="Aider" %}}
+```
+lima sudo apt install -y pipx
+lima pipx install aider-install
+lima sh -c 'echo "export PATH=$PATH:$HOME/.local/bin" >>~/.bash_profile'
+lima aider-install
+lima aider
