Bitatlas

Overview

Bitatlas is a Model Context Protocol server that provides zero-knowledge encrypted storage for humans and AI agents. It uses client-side AES-256-GCM encryption and is hosted in the EU, allowing AI assistants to securely store and retrieve sensitive data through MCP tools.

The server runs locally via the npm package @bitatlas/mcp-server, communicating over stdio. You'll need to set the BITATLAS_API_KEY environment variable to authenticate. The latest release is v1.1.0, published under the MIT license with source code available at bitatlas-group/bitatlas on GitHub.

Bitatlas is listed in the AI & Agents category on mcp.site and works with MCP clients including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, and Zed. If you maintain Bitatlas, claim this listing to verify ownership and keep information up to date.
