封闭接口:

McpClient
```
public static class McpClient.SyncSpec
extends java.lang.Object
```
Synchronous client specification. This class follows the builder pattern to provide a fluent API for setting up clients with custom configurations.
The builder supports configuration of:
- Transport layer for client-server communication
- Request timeouts for operation boundaries
- Client capabilities for feature negotiation
- Client implementation details for version tracking
- Root URIs for resource access
- Change notification handlers for tools, resources, and prompts
- Custom message sampling logic

  - capabilities
```
public McpClient.SyncSpec capabilities(McpSchema.ClientCapabilities capabilities)
```
    Sets the client capabilities that will be advertised to the server during connection initialization. Capabilities define what features the client supports, such as tool execution, resource access, and prompt handling.

    java.lang.IllegalArgumentException - if clientInfo is null
  - roots
```
public McpClient.SyncSpec roots(java.util.List<McpSchema.Root> roots)
```
    Sets the root URIs that this client can access. Roots define the base URIs for resources that the client can request from the server. For example, a root might be "file://workspace" for accessing workspace files.
    
    参数:
    
    roots - A list of root definitions. Must not be null.
    
    返回:
