About

InBox Wall is a local-first Python application that reads email over read-only IMAP and sanitizes the HTML before an AI assistant sees it. It removes text hidden with CSS, invisible Unicode characters and known prompt injection phrases, then serves the clean text through a local REST API and an MCP server. Blocked content goes to a separate vault database the AI cannot query.
