Troubleshooting

  • 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.
If you are on a Claude Team or Enterprise plan, a Claude Owner or Primary Owner needs to enable Mem for the organization before members can connect it.Ask the owner to add Mem in Organization settings -> Connectors. After Mem is available for the organization, connect your own Mem account from your Claude connector settings.
  • A direct 401 from https://mcp.mem.ai/mcp without auth is expected.
  • In your MCP client, reconnect Mem to refresh authentication and retry.
  • 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.
  • 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.
