Overview

From the repository's own README, as read at the audited commit. Badges and raw HTML are left out.

[](./LICENSE) [](https://pypi.org/project/memory-plus/) [](https://pepy.tech/projects/memory-plus)

A lightweight, local Retrieval-Augmented Generation (RAG) memory store for MCP agents. Memory-Plus lets your agent record, retrieve, update, and visualize persistent "memories"—notes, ideas, and session context—across runs.

🏆 First Place at the Infosys Cambridge AI Centre Hackathon!

Key Features

  • Record Memories:Save user data, ideas, and important context.
  • Retrieve Memories:Search by keywords or topics over past entries.
  • Recent Memories:Fetch the last N items quickly.
  • Update Memories:Append or modify existing entries seamlessly.
  • Visualize Memories:Interactive graph clusters revealing relationships.
  • File Import (since v0.1.2):Ingest documents directly into memory.
  • Delete Memories (since v0.1.2):Remove unwanted entries.
  • Memory for Memories (since v0.1.4):Now we use resources to teach your AI exactly when (and when not) to recall past interactions.
  • Memory Versioning (since v0.1.4):When memories are updated, we keep the old versions to provide a full history.

Questions

What is the Memory-Plus MCP server?

🧠 Memory-Plus is a lightweight, local RAG memory store for MCP agents. Easily record, retrieve, update, delete, and visualize persistent "memories" across sessions—perfect for developers working with multiple AI coders (like Windsurf, Cursor, or Copilot) or anyone who wants their AI to actually reme

What tools does Memory-Plus expose?

3 in total: 2 read-only, 1 that write, and 0 that can delete or overwrite. Every one is listed on this page with its risk.

Is Memory-Plus safe to connect to an agent?

The audit found nothing in the source that contradicts what it says it does, and graded it B (89/100). Grade A is held back for packages that have also passed a sandboxed behavioural run, which is why a clean server reads B.

What credentials does Memory-Plus need?

It reads GOOGLE_API_KEY from the environment. Give it a token scoped to the least it needs — an agent that can be talked into calling a tool can be talked into calling it with your credentials.

How current is this page?

The grade is for one exact copy of the source (568f545809cf), read on 2026-10-08. The repository is watched and re-audited when it changes.
