Nexo

Nexo is a local stdio MCP server that gives an AI assistant a cognitive memory layer, combining a multi-store memory model, retrieval and a knowledge graph.

What you can do

Provide a cognitive memory layer for the assistant, modeled on the Atkinson-Shiffrin memory model, with retrieval-augmented generation and a knowledge graph behind it. The description advertises more than 100 tools, but no tool list is supplied, so the exact operations cannot be confirmed. It runs as a local process on the user's machine over stdio.

When to use it

Consider it when you want an assistant to keep and recall context across sessions through a structured memory and knowledge graph rather than a plain note store. Because the tool list is unpublished, check the package's own documentation before relying on specific capabilities.

Requirements

Runs as a local process over stdio, installed from the npm package nexo-brain, so a Node.js runtime is needed. The manifest declares no authentication, environment variables or headers. Desktop only; no web executable.
