Description

MCPServer and ResourceManager have add_resource() method for static Resources, but there is no way to handle ResourceTemplate without using @resource decorator.

I am implementing the following workaround using the decorator for my usecase, but it is a bit odd.

server = MCPServer("...")

# Configure resources (implemented in other files)
server.resource("resource://users")(resources.list_users)
server.resource("resource://users/{id}")(resources.get_user)

References

It was implemented in #3208.

    I'd like to work on this. The change looks narrowly scoped: add the missing programmatic registration path for pre-built ResourceTemplate instances, symmetric with add_resource(), and cover listing/reading with focused tests. I also found the earlier #3208 implementation and its review history, so I can preserve the intended API shape while strengthening the assertions. Per this repository's contribution workflow, could a maintainer assign #3333 to me (@xixi-box) if you'd like me to proceed with the PR?
