Connect ChatGPT or Codex desktop

ChatGPT and Codex desktop can connect to Memside through an installed MCP server and OAuth. This flow does not require a Memside API key to be pasted into the app.

Before starting

• Sign in to Memside in a browser.
• Use an account with access to Plugins and MCP server installation.
• A workspace administrator may control access for managed accounts.

Current interface: Option 1

1. Open Plugin from the left bar.

2. Select Settings in the upper-right corner.

3. Open MCP.

4. Select Install MCP server.

5. Name the server Memside.

6. Set MCP Server URL to:

   https://api.memside.com/mcp/

7. Keep Authentication set to OAuth.

8. Install the server.

9. When prompted, sign in to Memside and approve the connection.

Previous interface

Some earlier ChatGPT versions use the following flow:

Memside should then appear in the Plugin area.

Note

Use the flow that matches the interface shown. OpenAI may change these labels or move the controls in a future app release. Managed workspaces may apply administrator permissions, and availability can vary by account, region, or supported surface.

Test the connection

Start a new chat, enable Memside when the app requests a Plugin or MCP server choice, and use a simple read request:

Find the most recent project checkpoint saved in Memside.

Review any request that writes or changes data before approving it.

Disconnect

Remove or disconnect Memside from the app’s Plugin settings. The OAuth connection can also be revoked from Memside settings. Disconnecting does not delete the Memside account or saved Memories.

If setup does not finish, see Troubleshooting.
