Mnemex MCP Server

A Model Context Protocol (MCP) server providing human-like memory dynamics for AI assistants. Memories naturally fade over time unless reinforced through use, mimicking the Ebbinghaus forgetting curve. It runs locally over stdio via the published package.

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

Claude Code

claude mcp add simplemindedbot-mnemex -- uvx mnemex

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "simplemindedbot-mnemex": {
      "command": "uvx",
      "args": [
        "mnemex"
