Memside is most useful when your saved context can move with you.

You might start a plan in ChatGPT, continue it in Claude, and later use a coding tool like Codex or Antigravity. Without a shared memory layer, each tool starts with only what you paste into that chat.

Connecting Memside to your AI apps gives those tools a way to find the context you saved. Instead of pasting chat history or downloading and moving a chat from one AI app to another, you can ask the AI to search Memside, load a checkpoint, follow an operating rule, or save a new note.

This guide explains the main connection options in simple terms.

The short version

For most AI apps, use MCP. MCP stands for Model Context Protocol. In practice, it lets an AI app connect to Memside as a tool. The AI can then search, read, create, and update memories when you ask it to.

Some apps, such as ChatGPT and Claude, can connect through an OAuth flow. That means you sign in with your Memside account instead of copying an API key manually.

Other tools, especially coding tools and developer apps, may ask for your Memside MCP server URL and an API access token.

Before you start

Open Memside and go to Settings > Developer & API.

That page shows the values most connection flows use:

- your MCP Endpoint URL

- your API Access Tokens

If a tool uses OAuth, you usually do not need to paste an API key into that tool. You sign in to Memside during the connection flow.

If a tool asks for an API key, generate one in Memside and save it immediately. Memside shows the full key only once. Do not put the key directly in a URL. Use it only where the app asks for an authorization header or token.

Connect Memside with ChatGPT

ChatGPT supports a custom plugin flow with OAuth. Managed workspaces may apply administrator permissions, and availability can vary by region or supported surface.

In ChatGPT:

1. Open the profile menu and select Settings.

2. Open Plugin or Security, depending on the interface shown.

3. Scroll down and turn on Developer mode.

4. Close Settings.

5. Open Plugins from the left panel.

6. Click the plus button in the upper-right corner.

7. Choose the option to add a custom plugin.

8. Add the Memside plugin details.

9. Set the MCP server URL to the URL shown in Memside.

10. Keep authentication set to OAuth and sign in.

For this flow, a Memside API key does not need to be pasted into ChatGPT. ChatGPT asks for authentication with Memside through OAuth.

After setup, Memside should appear in the ChatGPT plugin area. Restart ChatGPT once if the plugin does not appear immediately.

Keep Developer mode enabled in ChatGPT. If the option is unavailable in a managed workspace, an administrator may need to allow plugin access.

Connect Memside with Claude

Claude also supports a custom connector flow.

In Claude:

1. Open Settings.

2. Go to Connectors.

3. Click Add custom connector.

4. Name the connector Memside.

5. Add the Memside remote MCP server URL.

6. Sign in with your Memside account when Claude asks for authentication.

7. Restart Claude once after setup.

Claude uses OAuth for this connector flow. Once the connector is added and authenticated on Claude desktop or web, it is available on your Claude account and can be used from the Claude mobile app as well.

This is useful when you want to continue from a phone without typing a long setup prompt. You can ask Claude to get the relevant checkpoint or operating rule from Memside and continue from there.

Connect Memside with Codex

Codex is more technical than ChatGPT or Claude, but the idea is the same: add Memside as an MCP server.

In Codex, open the MCP server settings and add a new server using the Memside MCP endpoint. Depending on your Codex setup, you may use a UI form or a shared config file.

Most Codex MCP setups need:

• the Memside MCP server URL

• an authorization header using your Memside API access token

• a restart after saving the MCP settings

For detailed settings, refer to the Connections and API section in the Memside Help page.

After it is connected, you can ask Codex to search Memside for project context, load a checkpoint before editing code, or save a summary at the end of a session.

Connect Memside with Antigravity and other coding tools

Antigravity, Cursor, VS Code with Copilot, OpenCode, Claude Code, and similar tools usually connect through MCP configuration.

The exact settings screen is different in each app, but the values are usually the same:

• server name: `Memside`

• MCP server URL: the URL shown in Memside

• authorization: `Bearer` plus your Memside API access token

Some tools store this in a project-level config file. Others store it in a user-level config so the connection is available across projects. Use project-level setup when the memory connection should stay tied to one workspace.

Use user-level setup when you want Memside available everywhere.

For exact JSON examples, use the Connections and API section in the Memside Help page.

How to test the connection

After connecting an AI app, try a simple request:

Search my Memside memories for my latest checkpoint.

Or:

Create a note in Memside called Test Connection.

If the AI can find or create the memory, the connection is working.

Then try a real workflow:

Get the latest checkpoint for my website launch project from Memside and continue from there.

This is where the connection becomes useful. You are giving the AI a place to retrieve the context that still matters.

A few safety notes

Use OAuth when the app supports it. It is easier and avoids manually copying API keys.

Use API access tokens only for tools that need them. If you revoke or replace a token in Memside, update every tool that used the old one.

Do not save secrets as normal context for AI tools. Memside sensitivity settings help control what AI-connected workflows can access.

The main habit

Connecting Memside is only the first step. The habit that makes it valuable is simple:
Save the context you want the next AI session to use.

That might be an operating rule, a project note, a checkpoint, a decision, or a reference. Once it is saved in

Memside, ChatGPT, Claude, Codex, Antigravity, and other connected tools can work from the same source instead of asking you to repeat the same background.
