VS Code

VS Code reads the proxy endpoint, virtual key, and target model from claudeCode.environmentVariables in your settings.json. To switch providers later, change only the ANTHROPIC_MODEL value — everything else stays the same.

There are two ways to configure VS Code:

Method	Best for
Configure via CLI	Recommended. `sotatek-proxy setup` writes and backs up `settings.json` for you.
Configure via Extension	Manual setup when you want to inspect or edit every value yourself.

Choose the method first, then click the provider tab that matches your model provider.

Prerequisites

VS Code installed
sotatek-proxy installed and running on 127.0.0.1:3817
A Bifrost virtual key (sk-bf-xxx) — contact your admin

Configure via CLI

sotatek-proxy setup -p vscode writes all required env vars directly into VS Code’s settings.json — no manual file editing needed. It backs up the existing file before writing.

sotatek-proxy setup -p vscode -m fridayaix -k sk-bf-your-key

sotatek-proxy setup -p vscode -m minimax -k sk-bf-your-key

sotatek-proxy setup -p vscode -m deepseek -k sk-bf-your-key

Flag	Description
`-m` / `--model`	Model profile: `fridayaix`, `minimax`, `deepseek` (default: `fridayaix`)
`-k` / `--key`	Bifrost virtual key; falls back to existing settings or `ANTHROPIC_AUTH_TOKEN` env var
`--workspace`	Write to `.vscode/settings.json` in the current project instead of user-level
`--dry-run`	Preview target path without writing

Reload VS Code after running to apply the changes.

Configure via Extension

Prefer manual setup, or want to review each value? Configure the Claude Code extension directly through settings.json.

Step 1 — install Claude Code extension

VS Code → Extensions → search Claude Code → Install.

Step 2 — open `settings.json`

Cmd+Shift+P (macOS) or Ctrl+Shift+P (Windows/Linux) → Preferences: Open User Settings (JSON).

For workspace-only config, open the workspace settings.json instead.

Step 3 — paste env config

Replace sk-bf-your-virtual-key-here with your actual key. If settings.json already contains other keys, merge the claudeCode.environmentVariables entry — don’t create a second root {}.

}

Step 4 — switch model

To switch providers, update these four env vars together:

Env var	FridayAIX	MiniMax	Deepseek
`ANTHROPIC_MODEL`	`fridayaix/claude-sonnet-4-6`	`MiniMax/MiniMax-M3`	`deepseek/deepseek-v4-pro`
`ANTHROPIC_DEFAULT_OPUS_MODEL`	`fridayaix/claude-opus-4-8`	`MiniMax/MiniMax-M3`	`deepseek/deepseek-v4-pro`
`ANTHROPIC_DEFAULT_SONNET_MODEL`	`fridayaix/claude-sonnet-4-6`	`MiniMax/MiniMax-M2.7`	`deepseek/deepseek-v4-pro`
`ANTHROPIC_DEFAULT_HAIKU_MODEL`	`fridayaix/claude-haiku-4-5-20251001`	`MiniMax/MiniMax-M2.5-highspeed`	`deepseek/deepseek-v4-flash`

Step 5 — reload and verify

Save settings.json.
Developer: Reload Window if VS Code doesn’t pick up the change.
Open Claude Code chat: Hello, which model are you using?
Confirm no authentication error.

Quick reference

Setting	Value
Base URL	`http://127.0.0.1:3817/anthropic`
Token field	`ANTHROPIC_AUTH_TOKEN`
Model field	`ANTHROPIC_MODEL`
Token format	`sk-bf-xxx`

Troubleshooting

Issue	Solution
Authentication error	`ANTHROPIC_AUTH_TOKEN` is the Bifrost virtual key; `ANTHROPIC_BASE_URL` is `http://127.0.0.1:3817/anthropic`
Connection refused on `127.0.0.1:3817`	sotatek-proxy is not running. Run `sotatek-proxy status && sotatek-proxy start`.
Model not found	Verify exact `ANTHROPIC_MODEL` string with provider prefix and capitalisation
VS Code ignores new values	Save `settings.json` and run `Developer: Reload Window`
Broken `settings.json`	Validate JSON — check commas and brackets
