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

  - requestTimeout
```
public McpClient.SyncSpec requestTimeout(java.time.Duration requestTimeout)
```
    Sets the duration to wait for server responses before timing out requests. This timeout applies to all requests made through the client, including tool calls, resource access, and prompt operations.
    
    参数:
    
    requestTimeout - The duration to wait before timing out requests. Must not be null.
    
    返回:
    
    This builder instance for method chaining
    
    抛出:
    
    java.lang.IllegalArgumentException - if requestTimeout is null
  - initializationTimeout
```

```
    参数:
    
    initializationTimeout - The duration to wait for the initializaiton lifecycle step to complete.
    
    返回:
    
    This builder instance for method chaining
    
    抛出:
    
    java.lang.IllegalArgumentException - if initializationTimeout is null
  - 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.
    
    参数:
    
    capabilities - The client capabilities configuration. Must not be null.
    
    返回:
    
    This builder instance for method chaining
    
    抛出:
    
    java.lang.IllegalArgumentException - if capabilities is null
  - clientInfo
```
public McpClient.SyncSpec clientInfo(McpSchema.Implementation clientInfo)
```
    Sets the client implementation information that will be shared with the server during connection initialization. This helps with version compatibility and debugging.
    
    参数:
    
    clientInfo - The client implementation details including name and version. Must not be null.
    
    返回:
    
    This builder instance for method chaining
    
    抛出:
    
    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:
    
    This builder instance for method chaining
    
    抛出:
    
    java.lang.IllegalArgumentException - if roots is null
  - roots
```
public McpClient.SyncSpec roots(McpSchema.Root... roots)
```
    Sets the root URIs that this client can access, using a varargs parameter for convenience. This is an alternative to roots(List).
    
    参数:
    
    roots - An array of root definitions. Must not be null.
    
    返回:
    
    This builder instance for method chaining
