01 · Install Memharness

before you install - you'll need

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

Claude Code

claude mcp add las7-memharness -- npx -y @memharness/mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "las7-memharness": {
      "command": "npx",
      "args": [
        "-y",
        "@memharness/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.

npm package @memharness/mcp - the @memharness scope differs from the repo owner (las7); confirm it's the project's official package

registry namespace io.github.las7 is GitHub-verified and matches the repo owner
