Configuration `/config`

API Keys

muxd supports multiple providers. Set API keys via environment variables or /config:

/config set anthropic.api_key sk-ant-...
/config set openai.api_key sk-...
/config set brave.api_key BSA...

Or use environment variables:

export ANTHROPIC_API_KEY="sk-ant-..."
export OPENAI_API_KEY="sk-..."

Resolution order: environment variable > /config set preference.
