Hibp

Connects Claude to the Have I Been Pwned API for checking data breach exposure. Right now it exposes one tool: listing HIBP's canonical data class tags like "Email addresses" or "Passwords" for filtering breach information. Part of the broader Pipeworx gateway ecosystem, which packages 673+ data sources as MCP servers. You can use it standalone or through Pipeworx's ask_pipeworx natural language interface that handles tool selection and argument mapping automatically. Best for security workflows where you need to query breach data or understand what types of information have been compromised in known incidents.
