Nexus Memory System

What it does

Nexus Memory System provides a persistent, shared memory layer for AI coding agents. It allows agents to maintain context across sessions by capturing activity, distilling it into high-value memories, and performing 'dream cycles' to consolidate information and detect contradictions.

Tools

• store: Creates explicit memories with categories and labels.
• recall: Performs semantic and keyword-based retrieval of stored memories.
• represent: Builds a working representation of context using memories, digests, and insights.
• digest: Creates session summaries to reduce noise.
• dream: Runs consolidation cycles to reinforce patterns and compress memory.
• lineage: Explains the origin and evidence chain of a specific memory.

Installation

Add the following to your claude_desktop_config.json:

{
  "mcpServers": {
    "nexus": {
      "command": "nexus",

    }
  }
}

Note: Requires installation of the Nexus CLI via cargo build --release -p nexus-memory and running ./scripts/install.sh.
