BitAtlas MCP Server 🤖

Zero-Knowledge Cloud Drive persistence for AI agents.

This Model Context Protocol (MCP) server allows AI agents to securely interact with the BitAtlas vault. All files are encrypted client-side, meaning the server never sees the plaintext data.

Features

• Search & List Vault: Agents can browse encrypted file metadata.

• Secure Retrieval: Agents can fetch encrypted blobs and decryption metadata.

• Zero-Knowledge: The agent performs decryption locally using the user's provided master key.

Installation

For AI Agents (Claude Desktop, OpenClaw, etc.)

Add this to your MCP settings:

{
  "mcpServers": {
    "bitatlas": {
      "command": "npx",
      "args": ["-y", "@bitatlas/mcp-server"],
      "env": {
        "BITATLAS_API_KEY": "your-api-key",
        "BITATLAS_MASTER_KEY": "your-derived-master-key"
      }
    }
  }
}

x402 Wallet Mode (No Account Required)

Instead of an API key, agents can pay per request using a crypto wallet with USDC on Base:

{
  "mcpServers": {
    "bitatlas": {
      "command": "npx",
      "args": ["-y", "@bitatlas/mcp-server"],
      "env": {
        "BITATLAS_WALLET_PRIVATE_KEY": "0xabc...",
        "BITATLAS_MASTER_KEY": "your-64-hex-char-master-key"
      }
    }
  }
}

No signup. No API key. The agent pays per request in USDC and gets full vault access. Files include 30 days of storage and can be renewed.

Priority: If both BITATLAS_API_KEY and BITATLAS_WALLET_PRIVATE_KEY are set, the API key is preferred (free within quota).
