构造器详细资料

McpSyncServerExchange

public McpSyncServerExchange(McpAsyncServerExchange exchange)

Create a new synchronous exchange with the client using the provided asynchronous implementation as a delegate.

参数:

exchange - The asynchronous exchange to delegate to.

方法详细资料

getSession

public McpServerSession getSession()

getClientCapabilities

public McpSchema.ClientCapabilities getClientCapabilities()

Get the client capabilities that define the supported features and functionality.

返回:

The client capabilities

getClientInfo

public McpSchema.Implementation getClientInfo()

Get the client implementation information.

返回:

The client implementation details

createMessage

public McpSchema.CreateMessageResult createMessage(McpSchema.CreateMessageRequest createMessageRequest)

Create a new message using the sampling capabilities of the client. The Model Context Protocol (MCP) provides a standardized way for servers to request LLM sampling (“completions” or “generations”) from language models via clients. This flow allows clients to maintain control over model access, selection, and permissions while enabling servers to leverage AI capabilities—with no server API keys necessary. Servers can request text or image-based interactions and optionally include context from MCP servers in their prompts.

参数:

createMessageRequest - The request to create a new message

返回:

A result containing the details of the sampling response

listRoots

public McpSchema.ListRootsResult listRoots()

Retrieves the list of all roots provided by the client.

返回:

The list of roots result.

listRoots

public McpSchema.ListRootsResult listRoots(java.lang.String cursor)

Retrieves a paginated list of roots provided by the client.

参数:

cursor - Optional pagination cursor from a previous list request

返回:

The list of roots result
