+The same prefixing rules apply as with `import_server` for naming tools, resources, templates, and prompts. This includes prefixing both the URIs/keys and the names of resources and templates for better identification in multi-server configurations.
 
 <Tip>
     The `prefix` parameter is optional. If omitted, components are mounted without modification.
