Class SyncStatelessMcpPromptMethodCallback

java.lang.Object
org.springaicommunity.mcp.method.prompt.AbstractMcpPromptMethodCallback
org.springaicommunity.mcp.method.prompt.SyncStatelessMcpPromptMethodCallback
All Implemented Interfaces:
BiFunction<io.modelcontextprotocol.common.McpTransportContext,io.modelcontextprotocol.spec.McpSchema.GetPromptRequest,io.modelcontextprotocol.spec.McpSchema.GetPromptResult>
public final class SyncStatelessMcpPromptMethodCallback extends AbstractMcpPromptMethodCallback implements BiFunction<io.modelcontextprotocol.common.McpTransportContext,io.modelcontextprotocol.spec.McpSchema.GetPromptRequest,io.modelcontextprotocol.spec.McpSchema.GetPromptResult>
Class for creating BiFunction callbacks around prompt methods for stateless contexts. This class provides a way to convert methods annotated with McpPrompt into callback functions that can be used to handle prompt requests in stateless environments. It supports various method signatures and return types.

  • Method Details

    • validateParamType

      protected void validateParamType(Class<?> paramType)
      Overrides:
      validateParamType in class AbstractMcpPromptMethodCallback

    • assignExchangeType

      protected Object assignExchangeType(Class<?> paramType, Object exchange)
      Specified by:
      assignExchangeType in class AbstractMcpPromptMethodCallback

    • apply

      public io.modelcontextprotocol.spec.McpSchema.GetPromptResult apply(io.modelcontextprotocol.common.McpTransportContext context, io.modelcontextprotocol.spec.McpSchema.GetPromptRequest request)
      Apply the callback to the given context and request.

      This method builds the arguments for the method call, invokes the method, and converts the result to a GetPromptResult.

      Specified by:
      apply in interface BiFunction<io.modelcontextprotocol.common.McpTransportContext,io.modelcontextprotocol.spec.McpSchema.GetPromptRequest,io.modelcontextprotocol.spec.McpSchema.GetPromptResult>
      Parameters:
      context - The transport context, may be null if the method doesn't require it
      request - The prompt request, must not be null
      Returns:
      The prompt result
      Throws:
      McpPromptMethodException - if there is an error invoking the prompt method
      IllegalArgumentException - if the request is null

    • isSupportedExchangeOrContextType

      protected boolean isSupportedExchangeOrContextType(Class<?> paramType)
      Description copied from class: AbstractMcpPromptMethodCallback
      Checks if a parameter type is compatible with the exchange type.
      Specified by:
      isSupportedExchangeOrContextType in class AbstractMcpPromptMethodCallback
      Parameters:
      paramType - The parameter type to check
      Returns:
      true if the parameter type is compatible with the exchange type, false otherwise

    • validateReturnType

      protected void validateReturnType(Method method)
      Description copied from class: AbstractMcpPromptMethodCallback
      Validates that the method return type is compatible with the prompt callback.
      Specified by:
      validateReturnType in class AbstractMcpPromptMethodCallback
      Parameters:
      method - The method to validate

    • builder

      public static SyncStatelessMcpPromptMethodCallback.Builder builder()
      Create a new builder.
      Returns:
      A new builder instance
