Rmbr MCP Server

rmbr ("remember", vowels deleted) is an embedded, local-first memory + retrieval engine for AI agents and LLM apps - what SQLite is to Postgres, rmbr aims to be to hosted memory services.

People connecting memory tools to Claude, Cursor, VS Code, or another MCP client. The project is written in Python.

01 · Install Rmbr

before you install - you'll need

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

Claude Code

claude mcp add srock44-rmbr -- uvx rmbr

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "srock44-rmbr": {
      "command": "uvx",
      "args": [
        "rmbr"
      ]
    }
  }
}

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

Using another client? Same JSON, different key

02 · Evidence

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

repo age created 2026-07-30 - young repo, little track record yet

license MIT - declared in the repository

pypi package rmbr - check the name against the project README before installing (PyPI has no namespace ownership)

registry namespace io.github.SRock44 is GitHub-verified and matches the repo owner

v0.2.5 · 2026-08-01

What's new · Memory.bulk()/Index.bulk() - fixes a real O(n)-per-call cost: usearch has no incremental on-disk save, so every remember()/add_text() was re-serializing the entire vector index on every call. .bulk()…

Yes - it's a stdio server: it runs on your machine (via uvx) with your user's permissions. Your data stays local unless the server itself calls external APIs.
