Installation
Requirements: Node.js ≥ 20 — download here if you don't have it.
View on npm: @calibrate-ds/cli →
Mac / Linux
npm install -g @calibrate-ds/cli
ptb --version
If you get a permissions error, the recommended fix is to use nvm to manage your Node installation — it installs global packages without requiring
sudo. Alternatively, runsudo npm install -g @calibrate-ds/cli.
Windows
Open PowerShell as Administrator and run:
npm install -g @calibrate-ds/cli
ptb --version
Updating
npm install -g @calibrate-ds/cli
After updating, restart your AI IDE so it re-spawns the MCP server with the new binary. You will see [PTB MCP] vX.X.X started in your IDE's MCP logs to confirm which version is active.
