Sugar MCP Server

Persistent memory for AI coding agents. Your AI agent starts every session with amnesia. The architecture decisions, conventions, and gotchas you explained last week are gone. Sugar is the local-first memory layer that remembers them for you - per project, across projects, on your machine.

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

01 · Install Sugar

before you install - you'll need

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

Claude Code

claude mcp add roboticforce-sugar -- uvx sugarai

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "roboticforce-sugar": {
      "command": "uvx",
      "args": [
        "sugarai"
      ]
    }
  }
}

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

license no standard license detected - usage rights unclear; check the repo before commercial use

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

registry registry publisher io.github.cdnsteve is not the repo owner (roboticforce) - the registry entry was published by someone else

03 · What Sugar can do

Prose above is summarized from the project's README and registry record - no invented capabilities.

06 · Sugar FAQ

What is Sugar?

Is Sugar still maintained?

Yes - as of 2026-08-25, its last commit was 2026-08-24 and it shipped 1 release in the last 90 days. We re-verify nightly.

How do I install Sugar?

Does Sugar run locally?

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.
