Connect your AI tools to Mem using MCP

Connect your AI client to Mem’s MCP server.

We currently document setup for Claude, ChatGPT, Claude Code CLI, and Codex CLI.

Claude (web/desktop)

Use the following instructions to connect the Mem MCP server to Claude.

1. Open settings

2. Create app from MCP server

   In Apps settings, click Create app and configure your MCP server:

   https://mcp.mem.ai/mcp
   
3. Authenticate

   Complete OAuth when prompted.

Claude Code CLI

1. Add remote HTTP MCP server

Troubleshooting

OAuth flow does not open or complete

• Make sure your client can open a browser window for sign-in and consent.
• If the flow was interrupted, disconnect and reconnect the Mem connector in your client.
• Confirm you are signing in to the intended Mem account/workspace.

I get 401 Unauthorized

• A direct 401 from https://mcp.mem.ai/mcp without auth is expected.
• In your MCP client, reconnect Mem to refresh authentication and retry.

I get 429 Rate limit exceeded

• Reduce request frequency and batch larger operations when possible.
• Respect Retry-After before retrying.
• Review current limits at /api-reference/overview/rate-limits.

Mem tools do not appear in my client

• Verify the connector URL is exactly https://mcp.mem.ai/mcp.
• Re-list connectors/servers in your client and confirm Mem is enabled.
• Retry the setup flow for your client.

Claude is not finding the Mem tool I need

• In Claude, open the + menu, then go to Connectors and confirm Mem is enabled for the current conversation.
• Check Connectors -> Tool access. In On demand, Claude searches for the right connector before loading it, which can add an extra discovery step.
• If you need Mem to be available every time in that conversation, switch Claude to Always available.
• Be explicit in your prompt when needed, for example: Use the Mem connector for this task.
• If Claude still does not load Mem, disconnect and reconnect the Mem connector, then retry the conversation.

  • Use connectors to extend Claude’s capabilities
