# VS Code

> Run 9p inside your editor.

The 9th Protocol extension gives you two ways to work in VS Code.

## Commands

| Command                                   | What it does                    |
| ----------------------------------------- | ------------------------------- |
| **9th Protocol: Open Agent Panel**        | Chat panel docked in the editor |
| **9th Protocol: Open Session in Browser** | Full session in a browser tab   |

Both run against the same engine and the same `~/.9p` configuration as the CLI -
memory, skills, and MCP servers all apply.

## Panel

A side panel with the conversation, tool activity, inline permission prompts,
and the session meter. Good for staying in one window.

## Browser session

Opens the local session server (see [`9p serve`](/serve)) in a browser tab. More
screen space than a panel, and useful when you want the agent working while the
editor is doing something else.

## Setup

The extension uses whatever credentials the CLI has, so:

```bash theme={null}
9p login
```

is all the auth you need. See [Authentication](/authentication) for BYOK and
environment variables.

<Note>
  During private beta the extension is installed from a `.vsix` rather than the
  marketplace. Marketplace publishing lands with general availability.
</Note>

## Working directory

The extension uses the **first workspace folder** as the agent's working
directory. In a multi-root workspace, open the folder you want the agent to work
in as the primary root.
