context7-cli

Setup

If context7-cli is not installed, install it from GitHub:

npx api2cli install Melvynx/context7-cli

If context7-cli is not found, install and build it:

bun --version || curl -fsSL https://bun.sh/install | bash
npx api2cli bundle context7
npx api2cli link context7

api2cli link adds ~/.local/bin to PATH automatically. The CLI is available in the next command.

Always use --json flag when calling commands programmatically.
