## Customizing Separators
Both `import_server()` and `mount()` allow you to customize the separators used for prefixing components:
Both `import_server()` and `mount()` allow you to customize the separators used for prefixing components. The defaults are `_` for tools and prompts, and `+` for resources.

<Warning>
Be cautious when choosing separators. Some MCP clients (like Claude Desktop) might have restrictions on characters allowed in tool names (e.g., `/` might not be supported). The defaults (`_` for names, `+` for URIs) are generally safe.
</Warning>
<Tip>
To "cleanly" import or mount a server, set the prefix and all separators to `""` (empty string). This is generally unecessary but could save a couple tokens at the risk of a name collision!
