About

Leverages the Have I Been Pwned API to provide security checks directly within Claude, allowing users to quickly assess whether their email addresses or passwords have been compromised in known data breaches. Using k-anonymity, it securely checks passwords without transmitting the full password to the API. It also provides detailed information about specific breaches and allows listing all breaches, optionally filtered by domain, directly within Claude.
