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.
  • 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.
