cc-switch-cli

cc-switch

Switch between multiple Claude Code coding-plan subscriptions with one command.

If you've signed up for a few different Anthropic-compatible providers (official Anthropic, OpenRouter, DeepSeek, Moonshot/Kimi, Zhipu GLM, or your own proxy), each uses a slightly different set of environment variables. Swapping them by hand is fiddly and easy to get wrong. cc-switch stores them once, then:

1. Cleans your subprocess env of every variable any provider uses.
2. Injects the selected provider's env.
3. Launches claude with that environment.
4. On exit, your parent shell is untouched — nothing leaked.

Install

go install github.com/kotoyuuko/cc-switch-cli/cmd/cc-switch@latest

Or clone and build:

git clone https://github.com/kotoyuuko/cc-switch-cli
cd cc-switch-cli
make build   # binary at ./dist/cc-switch

Supported platforms: macOS, Linux. Windows users should use WSL.

Quick start

# 1. Add one or more providers.
cc-switch add official \
  --from-template anthropic-official \
  --env ANTHROPIC_API_KEY=sk-ant-xxxxxxxxx

cc-switch add or \
  --from-template openrouter \
  --env ANTHROPIC_AUTH_TOKEN=sk-or-xxxxxxxxx \
  --env ANTHROPIC_MODEL=anthropic/claude-opus-4

# 2. (Optional) set a default so bare `cc-switch` picks it.
cc-switch config set default official

# 3. Run claude with a chosen provider.
cc-switch use or
# or just `cc-switch` — opens an interactive picker in a tty.

cc-switch passes its exit code through from claude, forwards SIGINT / SIGTERM / SIGHUP, and inherits stdio verbatim — it behaves like a thin wrapper.

Commands

Command	What it does
cc-switch add <name> [--env K=V ...] [--from-template T] [--non-interactive]	Register a provider.
cc-switch list [-V]	Show providers; -V includes masked env keys.
cc-switch edit <name> [--env K=V] [--remove-env K] [--description ...]	Modify a provider.
cc-switch remove <name>	Delete a provider (clears default_provider if applicable).
cc-switch use [<name>]	Clean → inject → launch claude. Interactive picker when tty + no name.
cc-switch config show / set / get	Inspect or change claude_path / default_provider.
cc-switch templates list / show <t>	Explore built-in env-key skeletons.
cc-switch version	Print build info.

Flags that work everywhere:

• -v / --verbose: trace config path, resolved claude path, union keys, injected keys (never values) to stderr.
• --config <path>: override config file location (beats $CC_SWITCH_CONFIG).

Using references to keep secrets out of the config file

Instead of pasting your API key into config.yaml, you can reference any env variable present in your shell when cc-switch use runs:

providers:
  official:
    env:
      ANTHROPIC_API_KEY: env:MY_ANTHROPIC_KEY   # resolved at launch
      ANTHROPIC_BASE_URL: https://api.anthropic.com

Pair it with 1Password CLI, direnv, or any other secret-exposing tool:

# ~/.zshrc
export MY_ANTHROPIC_KEY="$(op item get 'Anthropic API' --field credential)"
cc-switch use official

If the referenced variable is missing at launch, cc-switch refuses to start claude and tells you which key referenced which missing variable — no silent fallbacks.

Why "union" cleanup?

When cc-switch use foo runs, the cleanup step removes every env key that appears in any configured provider, not just the currently selected one. That way, if you used openrouter last time and it set ANTHROPIC_AUTH_TOKEN, switching to official (which only sets ANTHROPIC_API_KEY) doesn't leave the stale auth token around to confuse claude.

Consequence: if a provider uses a key you haven't registered anywhere, that key won't be cleaned. So register every key you might use in at least one provider.

Config file

Located via $CC_SWITCH_CONFIG → $XDG_CONFIG_HOME/cc-switch/config.yaml → ~/.config/cc-switch/config.yaml. Permissions are 0600 on create; if yours become more permissive, cc-switch prints a warning on every invocation.

Example config (examples/config.example.yaml):

claude_path: ~/.claude/local/claude
default_provider: official

providers:
  official:
    description: "Anthropic official"
    env:
      ANTHROPIC_API_KEY: env:MY_ANTHROPIC_KEY
      ANTHROPIC_BASE_URL: https://api.anthropic.com

  openrouter:
    env:
      ANTHROPIC_BASE_URL: https://openrouter.ai/api/v1
      ANTHROPIC_AUTH_TOKEN: sk-or-example
      ANTHROPIC_MODEL: anthropic/claude-opus-4

Non-goals (v1)

• Not a secret vault — values are stored in plain YAML (mitigations: 0600 permissions and env:VAR indirection).
• Doesn't modify your shell profile, doesn't export anything into your parent shell — env changes live only in the claude subprocess.
• No Windows support (macOS / Linux only; WSL works).
• No user-supplied template directory (built-ins only; PRs welcome).
• No chained env:VAR resolution (one hop only).
• No escape for a literal env: prefix at value start (rare; file an issue if you hit it).
