What is the Memory Plus MCP server?

Memory Plus becomes available to MCP clients through the memory plus mcp server. 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.

What Memory Plus does

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.

Key capabilities

  • 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

Tools it exposes

Once connected, the assistant can call this tool directly:

  • Memory — plus has a few dependencies that can be slow to download the first time. It typically takes around 1 minute to fetch everything needed

Installing the memory plus mcp server

The server is distributed via npm as @modelcontextprotocol/inspector, so most clients can run it without a manual build step. Add it to your MCP client's configuration and restart the client to pick it up — the copy-paste configs for Claude Desktop, Claude Code and Cursor are on this page.

Configuration

Before the server will start you need to supply 2 environment variables: GOOGLE_API_KEY, YOUR_API_KEY. Keep credentials in your client's env block or a secrets manager rather than committing them.

Where it fits

Knowledge and memory servers address the most frustrating trait of language models — walking into every conversation with no recollection of the last one. Memory Plus sits in that group, and the shape of its toolset — Memory — tells you what it is really for. Worth comparing against the other knowledge memory servers in this directory before you commit to one, since several overlap in scope but differ sharply in setup cost and permissions.

Practical notes

  • This server runs locally, so it operates with whatever access your machine and its credentials already have. Scope that deliberately rather than by default.
  • It will not start until its required credentials are present, so set those before wondering why the tools never appear.
  • Maintained by Yuchen20, written in Go.
  • MCP clients ask for confirmation before each tool call by default. Keep that on while you learn what the memory plus mcp server actually does with your data.
  • Every entry in this directory is reviewed by hand before it goes live, and details are checked against the project's own documentation.
