What can you do with this server?

The @bitatlas/mcp-server allows AI agents to securely manage a zero-knowledge, end-to-end encrypted cloud vault using client-side AES-256-GCM encryption. Available capabilities: * Vault Status: Check vault health, total file count, and storage usage. * List Files: Browse files with optional filters by folder, category (identity, financial, legal, medical, digital), or search term. * Search Files: Search vault files by query string, optionally narrowed to a specific category. * Get/Download a File: Retrieve file metadata and decrypt file content — returned as UTF-8 text for text files or base64 for binary files (requires BITATLAS_MASTER_KEY). * Upload a File: Read a local file, encrypt it client-side, and upload it to the vault with an optional display name, category, and destination folder (requires BITATLAS_MASTER_KEY; max 100 MB). * Delete a File: Permanently remove a file from the vault by its UUID. * Create a Folder: Organize the vault by creating new folders at the root or nested under a parent folder.

BitAtlas

Zero Knowledge Cloud Drive for Humans and Agents

BitAtlas is a next-generation cloud storage platform designed with privacy and AI agents in mind. It provides a secure, zero-knowledge environment where your most sensitive documents are encrypted client-side and accessible only to you and the agents you authorize.

🚀 Vision

BitAtlas aims to be the secure "atlas" for your digital life, providing a foundation for both human productivity and AI agent assistance without compromising on privacy.

✨ Key Features

🛡️ E2E Encryption (AES-256-GCM): All files are encrypted in the browser (or at the SDK level) before being uploaded. The server never sees your plaintext data or your encryption keys.
🤖 Agent-Native (MCP Server): Built from the ground up to support AI agents via the Model Context Protocol (MCP). Let your agents safely search, read, and manage your vault.
🔐 Personal Vault: A dedicated space for your most critical documents—identity papers, property deeds, medical records, and digital assets.
🇪🇺 European Data Sovereignty: All infrastructure is hosted on European soil, subject to the world's strongest privacy regulations (GDPR).
💸 Pay-per-Request (x402): Anonymous access via the x402 payment standard. Agents pay with USDC stablecoins on Base — no account, no API key, no KYC. Files include 30 days of storage with pay-to-renew. Learn more →

🏗️ Project Structure

mcp-server/: The Model Context Protocol server for integrating with AI agents like Claude Desktop, OpenClaw, and more.
sdk/encryption/: The core encryption logic used for client-side security.

🌐 Ecosystem

LegacyShield (legacyshield.eu): The first production application built on BitAtlas. A digital legacy platform and encrypted document vault for humans and their descendants.

bitatlas_searchB

Search vault files by a query string, optionally narrowed to a category.

Inputs: query (required), category.

bitatlas_upload_fileA

Read a local file, encrypt it client-side with AES-256-GCM, and upload it to the vault. Requires BITATLAS_MASTER_KEY. Files over 100 MB are not supported via MCP.

Inputs: file_path (required), name, category, folder_id.

A3.7/5.0

Scored 2026-04-13 09:45 across 7 tools

Disambiguation5/5

Each tool has a clearly distinct purpose with no ambiguity: create_folder, delete_file, get_file, list_files, search, upload_file, and vault_status all target specific, non-overlapping operations in the file vault domain. The descriptions reinforce these distinctions, making misselection unlikely.

Naming Consistency5/5

All tools follow a consistent 'bitatlas_verb_noun' pattern with snake_case throughout (e.g., bitatlas_create_folder, bitatlas_delete_file). This predictability makes the tool set easy to navigate and understand at a glance.

Tool Count5/5

With 7 tools, the count is well-scoped for a file vault management server. Each tool earns its place by covering essential operations like CRUD for files/folders, listing, searching, and status checks, without being overly sparse or bloated.

Completeness5/5

The tool set provides complete CRUD/lifecycle coverage for the vault domain: create (upload_file, create_folder), read (get_file, list_files, search), update (implied via re-upload), delete (delete_file), and administrative status (vault_status). There are no obvious gaps that would hinder agent workflows.
