The documentation and comments for the MCP Client section contain errors.

[sunyuhan1998]

In the documentation for the MCP Client (https://docs.spring.io/spring-ai/reference/1.1-SNAPSHOT/api/mcp/mcp-client-boot-starter-docs.html#_configuration_properties), the description for the name configuration property states:

Name of the MCP client instance (used for compatibility checks).

However, the client name is not actually used as part of any compatibility check.

Similarly, the comments in the configuration classes for both the MCP Client and MCP Server regarding the name and version properties also appear to be incorrect:

spring-ai/auto-configurations/mcp/spring-ai-autoconfigure-mcp-client-common/src/main/java/org/springframework/ai/mcp/client/common/autoconfigure/properties/McpClientCommonProperties.java

Lines 43 to 55 in 59f2b3b

	/**
	* The name of the MCP client instance.
	* <p>
	* This name is reported to clients and used for compatibility checks.
	*/
	private String name = "spring-ai-mcp-client";
	/**
	* The version of the MCP client instance.
	* <p>
	* This version is reported to clients and used for compatibility checks.
	*/
	private String version = "1.0.0";

spring-ai/auto-configurations/mcp/spring-ai-autoconfigure-mcp-server/src/main/java/org/springframework/ai/mcp/server/autoconfigure/McpServerProperties.java

Lines 69 to 74 in 59f2b3b

	/**
	* The version of the MCP server instance.
	* <p>
	* This version is reported to clients and used for compatibility checks.
	*/
	private String version = "1.0.0";

In reality, neither the name nor the version attributes on either the client or server side are used for compatibility validation. The only property related to compatibility checking is io.modelcontextprotocol.spec.McpTransport#protocolVersion, which can be confirmed by examining the io.modelcontextprotocol.client.LifecycleInitializer#doInitialize method in the MCP Java SDK:
