MemPalace Cloud Plugin

Plugins and skill packs for MemPalace Cloud — persistent AI memory as a service.

What it does

1. Connects your AI tool to MemPalace Cloud via OAuth MCP (no API keys, no local setup)
2. Teaches the AI to use memory proactively — recall facts before answering, save learnings after tasks
3. Everything reviewed — captured memories land in your Inbox for approval before becoming permanent

Installation

Claude Code (plugin — recommended)

claude plugin add github:cschnatz/mempalace-cloud-plugin

Installs MCP connection + memory skill in one command. On first use, opens browser for OAuth login.

Codex CLI (one-liner)

macOS / Linux:

curl -sL https://www.mempalace.cloud/skill-packs/install-codex.sh | bash

Windows (PowerShell):

irm https://www.mempalace.cloud/skill-packs/install-codex.ps1 | iex

Adds the MCP server (with OAuth login) and downloads the memory skill into your project's AGENTS.md.

Claude Desktop

claude mcp add mempalace-cloud --transport http https://api.mempalace.cloud/mcp -s user

Then add the memory instructions to your Project Settings. See skill-packs/claude-desktop.md for the full instruction block.

Cursor

Add to your MCP settings:

{
  "mcpServers": {
    "mempalace-cloud": {
      "url": "https://api.mempalace.cloud/mcp"
    }
  }
}

Then add the memory instructions to Cursor Rules. See skill-packs/cursor.md for the full instruction block.

What happens after install

Your AI gains 15+ memory tools (mempalace_search, mempalace_kg_query, mempalace_diary_write, etc.) and a skill that tells it:

• Before responding about a person, project, or past event → search memory first
• After completing a significant task or learning something → save it to memory
• Never invent — if memory has nothing, say so explicitly

Your memories persist across sessions, projects, and tools. Every conversation builds on the last.

Requirements

• A MemPalace Cloud account (free tier at mempalace.cloud)
• One of: Claude Code, Codex CLI, Claude Desktop, or Cursor

Verification

After installing, ask your AI: "What do you know about my preferences?"

It should call mempalace_search or mempalace_kg_query before answering. If it doesn't, check that the MCP server is connected and restart your tool.

Troubleshooting

AI says "I don't have memory tools"

• Claude Code: Run claude mcp list — you should see mempalace-cloud with status connected
• Codex: Run codex mcp list — and check that AGENTS.md exists in your project with the Memory Protocol section
• If not listed, reinstall (plugin for Claude Code, install script for Codex)

OAuth login doesn't complete

• Make sure you have a MemPalace Cloud account at mempalace.cloud
• Check that your browser opened the login page (pop-up blockers can interfere)

Memories are captured but don't show up

• New memories land in your Inbox first — check the Inbox
• Items auto-approve after 24 hours if you don't review them
