Add the LongMemory (formerly OpenMemory) MCP server to VS Code

Config last verified Nov 10, 2026

The exact config to run LongMemory (formerly OpenMemory) in VS Code — paste it in, restart, and the tools load.

Prerequisites

  • VS Code installed.

Setup

1. Open .vscode/mcp.json

2. Add this configuration

Add to .vscode/mcp.json

.vscode/mcp.json
json
{
  "servers": {
    "openmemory": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "longmemory",
        "mcp"
      ],
      "env": {
        "LM_DB_PATH": "<LM_DB_PATH>",
        "LM_TIER": "<LM_TIER>",
        "LM_EMBEDDINGS": "<LM_EMBEDDINGS>"
      }
    }
  }
}

Heads up

  • VS Code uses the `servers` key (not `mcpServers`) and requires `type`.

3. Restart VS Code and confirm the LongMemory (formerly OpenMemory) tools load.

Gotchas

  • VS Code uses the `servers` key (not `mcpServers`) and requires `type`.

VS Code is the exception to every other client: its top-level key is "servers", not "mcpServers", and each entry needs an explicit "type" (for example "http" or "stdio"). Secrets are not inlined; instead you declare an "inputs" array and reference each value as ${input:id}, so VS Code prompts for it once and never writes it to disk. Remote servers connect natively with OAuth.
