None — local process

Environment variables

MEMORY_FILE_PATH

Config (mcpServers block)

{
  "mcpServers": {
    "memory": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-memory"
      ]
    }
  }
}

From the server's own docs — the exact command and args it documents for local/stdio use.

03 / Permissions

What installing this server actually grants access to, as documented by its own source — not True LLMs' assessment.

Local memory storage file (JSONL, default memory.jsonl)Read / Write

From the source's own docs

  • Storage is a plain local JSONL file — anything written to memory persists in cleartext at MEMORY_FILE_PATH.

04 / Compatibility

Scope: compatibility below is what each skill's own source states, not an independent test — True LLMs hasn't run these against live agents yet. Marked confirmed by source where the repo says so, untested everywhere else.
