Emem, The Verifiable Memory Protocol For The Physical World MCP Server

emem is the shared memory layer for multi-agent systems. Two agents that share no model, no vendor, and no trust can cite the same signed fact and each verify it alone. Satellites fill the memory today; any machine that watches the world joins by proving how it ran.

People who need memory tools inside Claude, Cursor, VS Code, or another MCP client. The project is written in Rust.

01 · Install Emem, The Verifiable Memory Protocol For The Physical World

before you install - you'll need

The README does not document required environment variables for a basic install.

Claude Code

claude mcp add vortx-ai-emem --transport http https://emem.dev/mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "vortx-ai-emem": {
      "url": "https://emem.dev/mcp"
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key
