Cloudflare overhauls its Command-Line Interface (CLI) for AI use cases, with agents now accounting for 48% of its usage.

Beating AI Express: Cloudflare has significantly expanded its `cf` CLI, which it launched in April this year. Initially supporting only a small number of products, the tool now covers all over 3,000 of Cloudflare’s API operations and is positioned to replace the existing Wrangler, which currently has around 280 command paths. Many of `cf`’s designs are tailored for coding agents: command outputs default to JSON, enabling direct reading by agents like Claude Code and Codex. The new `cf cli search` feature lets agents describe tasks in natural language to automatically find corresponding commands, no prior knowledge of Cloudflare’s APIs required. Cloudflare disclosed that agents now account for nearly half of Wrangler’s usage: the proportion stood at ~25% in March this year, rising to 48% in the latest week. Agents use nearly twice as many distinct commands on average as humans, and are nearly four times more likely to execute six or more commands. The configuration system has also been revised: `cf` now uses a TypeScript-based `cloudflare.config.ts`, allowing agents to leverage type checking and autocompletion to identify configuration errors directly. Existing projects can migrate via `cf migrate`, though some JavaScript projects dependent on Wrangler’s build workflow, plus Rust and Python Workers, will remain on Wrangler for now. Cloudflare plans to release Wrangler’s final major version after `cf` stabilizes, followed by 18 months of maintenance.
