Xmemo MCP Server

XMemo is a user-owned Memory OS for AI agents: persistent memory, project context and session continuity with agent identity, provenance and governed access, shared across AI clients through MCP, the CLI and a public REST API surface.

People who work with ai memory and streamable http and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in JavaScript.

01 · Install Xmemo

before you install - you'll need

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

Claude Code

claude mcp add yonro-memory-os-cli --transport http https://xmemo.dev/mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "yonro-memory-os-cli": {
      "url": "https://xmemo.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

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions · remote - your agent's requests go to xmemo.dev

endpoint auth requires authentication - rejected our unauthenticated MCP initialize

license MIT - declared in the repository

npm package @xmemo/client - the @xmemo scope differs from the repo owner (yonro); confirm it's the project's official package

registry namespace io.github.yonro is GitHub-verified and matches the repo owner
