cli-printing-press is an open-source dev tools project by mvanhorn (mvanhorn/cli-printing-press on GitHub). It has 4,794 GitHub stars and 518 forks, is released under the MIT license, and was last updated on GitHub on 8 October 2026.
Choose the service you want a CLI for — a documented API, or a site whose traffic can be sniffed.
Install both the generator binary and the Printing Press skills; each side needs the other.
Launch your agent (Claude Code recommended) and invoke the /printing-press command with your target.
Review the generated CLI's quality score and verification proofs, then publish it to the library if you want to share it.
Generates the complete API surface plus the best features of competing tools, then adds compound insight commands.
Printed CLIs sync data into domain-specific SQLite tables with FTS5 search, so queries and compound commands work offline in milliseconds.
Every run produces both a Cobra CLI (`-pp-cli`) and an MCP server (`-pp-mcp`) from one spec, sharing client, store, and auth.
Point it at a website and it captures browser traffic to reverse-engineer the API and generate a spec.
Auto-JSON when piped, --compact modes that cut token use, typed exit codes, and --dry-run for safe exploration.
Four mechanical checks — scorecard, dogfood, proof-of-behavior, and a live API smoke test — run before a CLI ships.
Clone for the developer path, or use the installer in the next step for normal installs.
git clone https://github.com/mvanhorn/cli-printing-press.git
cd cli-printing-pressThe installer runs `go install` for the generator and refreshes the Printing Press skills (Go 1.26.6+, Node/npm required).
curl -fsSL https://raw.githubusercontent.com/mvanhorn/cli-printing-press/main/scripts/install.sh | bash
cli-printing-press --versionStart Claude Code and invoke the press with an API name or a website URL.

# then inside Claude Code:
/printing-press NotionDeveloper mvanhorn; the approach credits Peter Steinberger's discrawl and gogcli tools as the playbook it automates.
Yes — the generator is MIT-licensed and the printed CLIs are yours. You will typically need a Claude Code (or Codex) setup to drive the skills, which may involve your own subscription.
The press itself needs no key, but printing a CLI for a service usually requires that service's own credentials for live verification, and the agent driving it uses your existing Claude Code/Codex access.
Typical generators wrap endpoints and stop. The Printing Press also studies competing tools, adds a local SQLite sync/search layer and compound commands, verifies behavior mechanically, and emits both a CLI and an MCP server.
Run the install script (or `go install github.com/mvanhorn/cli-printing-press/v4/cmd/cli-printing-press@latest` plus the skills), then start Claude Code and run `/printing-press <API or URL>`.
