model-switcher

cc-model-switcher

Claude Code plugin + CLI for switching the active model while keeping the same provider/auth config.

What it does

• Fetches live model IDs from current provider (ANTHROPIC_BASE_URL → /models) or CPR_MODELS_URL
• Enriches live IDs with bundled metadata seed plus optional local override from CPR_MODEL_METADATA_FILE or ~/.claude/model-switcher/proxy-model-metadata-fixed.json
• Updates only model fields in ~/.claude/settings.json
• Keeps provider switching and model switching separate

Install as Claude Code plugin

/plugin marketplace add mrichlaz/cc-model-switcher
/plugin install model-switcher@cc-model-switcher

Restart Claude Code after installing.

Plugin commands

List live models:

/model-switcher:models

Switch model:

/model-switcher:model provider/model-id

CLI

Build:

npm install
npm run build

Interactive model picker:

cc model
# or
cc model switch

List models:

CPR_MODELS_URL='https://your-proxy.example/v1/models' cc --models

Switch model directly:

cc model switch provider/model-id

Environment

Optional live models URL override:

export CPR_MODELS_URL='https://your-proxy.example/v1/models'

If unset, the tool derives /models from current Claude ANTHROPIC_BASE_URL, so cc provider switch <profile> changes the model list automatically.

Optional metadata seed override:

export CPR_MODEL_METADATA_FILE='/path/to/proxy-model-metadata.json'

Bundled metadata seed:

data/model-metadata-seed.json

Optional local override path:

~/.claude/model-switcher/proxy-model-metadata-fixed.json

Provider switching:

cc provider
cc provider list
cc provider switch <profile>

Model switching uses the active provider after provider switch.

Claude auth note

Use either apiKeyHelper in ~/.claude/settings.json or ANTHROPIC_AUTH_TOKEN in environment, not both.
