# Neon CLI command: set-context

The `set-context` command sets a background context for your CLI sessions, so you don't have to specify the project ID in every command. The context is saved to a default `.neon` file in the current directory, or to a [named context file](#using-a-named-context-file) of your choice, and stays in place until you reset it or remove the file.

:::callout{intent="note" title="Deprecated"}
`set-context` is deprecated in favor of [`neon link`](/guides/apis-sdks-cli-link), which writes the same `.neon` context file. It still works but prints a deprecation warning when you run it, and may be removed in a future release. Use `neon link` to set project context; it verifies your inputs and infers your organization. For a write-without-checks behavior like `set-context` (for example, in scripts), use `neon link --no-checks` with `--org-id`, `--project-id`, and `--branch`. To switch branches, use [`neon checkout`](/guides/apis-sdks-cli-checkout).
:::

:::callout{intent="note" title="How the CLI finds your .neon file"}
When you run a command, the CLI starts in your current directory and checks for a `.neon` file. If it does not find one, it checks the parent directory, then the parent of that, and so on until it finds a `.neon` file or reaches your home directory. This means you can run commands from any subdirectory of a linked project without re-specifying `--project-id`.

To write context to a specific file or location, use `--context-file`.
:::

## Usage

```bash
neon set-context [options]
```

To save the context to a file other than the default `.neon` file, add the global `--context-file <your_context_file>` option. You can switch contexts by providing different files.

## Options

| Option         | Description     | Type   | Default | Required |
| -------------- | --------------- | ------ | ------- | -------- |
| `--branch-id`  | Branch ID       | string | —       | No       |
| `--org-id`     | Organization ID | string | —       | No       |
| `--project-id` | Project ID      | string | —       | No       |

Set at least one of these options.

## Using the default context file

Set the context to the default `.neon` file:

```bash
neon set-context --project-id patient-frost-50125040 --org-id org-bright-sky-12345678
```

List all branches for this project with `branches list`, without including `--project-id` or `--org-id`, even if you belong to multiple organizations or have multiple projects:

```bash
neon branches list
```

```title="Output"

```

## Using a named context file

Set the context to the context file of your choice:

```bash
neon set-context --project-id plain-waterfall-84865553 --context-file Documents/MyContext
```

List all branches with `branches list`. The context file provides the project:

```bash
neon branches list --context-file Documents/MyContext
```

```title="Output"
┌─────────────────────────────┬─────────────┬─────────┬──────────────────────┬──────────────────────┐
│ Id                          │ Name        │ Default │ Created At           │ Updated At           │

└─────────────────────────────┴─────────────┴─────────┴──────────────────────┴──────────────────────┘
```

:::callout{intent="note"}
These two `branches list` commands use independent contexts in the same account: the default `.neon` file points to `patient-frost-50125040`, while the named context file points to `plain-waterfall-84865553`. You can set as many context files as you'd like, using unique names or different directories.
:::

## Setting context when creating a new project

Use `--set-context` to set the project context at creation time:

```bash
neon projects create --name MyLatest --set-context
```

This creates a hidden `.neon` file by default with the following context:

```json
{
  "projectId": "quiet-water-76237589"
}
```

Commands that would normally require `--project-id` now default to this context.

## Reset or remove context

To clear the current context, either:

1. Run the `set-context` command with no options:

   ```bash
   neon set-context
   ```

2. Delete the `.neon` file (or your custom `--context-file`):

   ```bash
   rm .neon
   # Or for a custom context file:
   rm your_context_file
   ```

## `.gitignore`on first create

The first time a `.neon` file is created in a directory, the CLI adds `.neon` to `.gitignore` in that same folder:

- If no `.gitignore` exists, the CLI creates one with a single `.neon` line.
- If `.gitignore` already exists, the CLI appends `.neon` only if it is not already listed.

This keeps local project settings out of git by default. If you want to commit `.neon` and share context with your team, remove the entry from `.gitignore`. The CLI will not re-add it when updating an existing `.neon` file.

:::callout{intent="note"}
Neon does not save any confidential information to the context file (for example, auth tokens). You can safely commit this file to your repository or share with others.
