ChatGPT

Connect ChatGPT to MemPalace Cloud in three steps: enable Developer Mode, add the MCP connector, then paste the memory instructions.

ChatGPT requires a Teams, Pro, or Enterprise plan for MCP support. Free and Plus plans do not include Developer Mode. Developer Mode is only available on Web and Desktop — not the mobile app.

Prerequisites

Installation

Step 1: Enable Developer Mode

Open ChatGPT Settings → Apps → Developer Mode and toggle it on.

If you are on a Teams plan and don't see this option, ask your workspace admin to enable it under Workspace Settings → Permissions & Roles.

Step 2: Add the MCP connector

Click Settings → Connectors → Create and enter:

  • Name: MemPalace Cloud
  • Description: Persistent memory — search, store, and recall facts, decisions, and context across sessions
  • Connector URL: https://api.mempalace.cloud/mcp

Click Save. A browser window opens for OAuth login — sign in with your MemPalace Cloud account. Once connected, ChatGPT shows the available tools (mempalace_search, mempalace_add_drawer, etc.).

Step 3: Paste the memory instructions

The full instruction block is hosted at:

https://mempalace.cloud/skill-packs/chatgpt-instructions.md

Copy its content and paste it into ChatGPT Custom Instructions.

The hosted block is kept in sync with the plugin (currently v1.3.0) and includes:

  • Discovery First — ChatGPT reads the palace structure before writing
  • Save Decision Flow — a three-question flow to prevent flat dumps
  • Anti-patterns — no silent creation, no generic dumps

Verification

Open a new ChatGPT conversation and ask:

"What do you know about my preferences?"

ChatGPT should call mempalace_list_wings first (discovery), then mempalace_search before answering — you'll see the tool invocation in the chat.

Updates

When the skill pack version bumps (e.g., v1.3.0 → v1.4.0), re-copy the hosted block into your Custom Instructions to stay current. There is no automatic update path for pasted instructions.

Troubleshooting

Developer Mode option not visible You need a Teams, Pro, or Enterprise plan. On Teams, the workspace admin must enable it first. Developer Mode is not available on the mobile app.

Connector shows an error Verify the URL is correct: https://api.mempalace.cloud/mcp. Try https://api.mempalace.cloud/healthz in your browser — it should return {"status":"ok"}.
