How do I install PreReason?

Pick a client above and copy the generated config. Cursor and VS Code also have a deep link when the server can run locally or remotely.

Is PreReason official?

No. Registry-listed is not the same as vendor-official. Read the methodology for the difference.

How is the trust score calculated?

This listing scores 40 (Fair). The formula is published on the methodology page.

Environment

Name	Required	Notes
PREREASON_API_KEY	No	PreReason API key (starts with pr_live_). Optional: without it the bridge asks for access from inside the session and prints one link for you to approve; the key is then saved under ~/.prereason. Or sign up at prereason.com. Secret.
PREREASON_CLIENT	No	The app this bridge runs in (claude-desktop, cursor, windsurf, claude-code, ...), so your PreReason dashboard names the connection.
