It's also possible to reload a tool's configuration via the Admin
interface. However, it's not possible to add and remove tools. This
is something we'd like to support, but have not yet done. There's an
issue for it which you can track here:

The tools generated depend on certain parameters so there can be an arbitrary number of tools generated. Installing them manually and restarting the server is not ideal in this situation since it would depend on an administrator doing the work (rather than the user).

> Hello,

> We here at the Universoty of Georgia have developed a suite of tools to enable accessing Web services through Galaxy's interface, one time and also in workflows. We do this by reading the descriptions of the Web services (from WSDLs and WADLs) and adding tools dynamically to Galaxy that are able to take correct inputs from the user and invoke these services.
>
> Though most of this functionality was added by adding tools, we had to make minimal change in Galaxy's source code to support the capability of refreshing Galaxy toolbox without restarting the server.
> This is hardly 5 lines of code that was added to Galaxy's code base.
> These tools will be available shortly
> on the community page. I was wondering if it will be possible to add the support for dynamic tool addition to the main instance of Galaxy. Please find the details below:
