         return Ok(CallToolResult::text_content(
                      format!( "Successfully created directory {}", path),
                      None,
                  ));
  
  }

v0.1.8

0.1.8 (2025-02-23)

Features

• add SdkError codes and types (#37) (034ee8f)
• add utility function for easy detection of initialized notifications (#38) (39400b6)

v0.1.7

0.1.7 (2025-02-21)

Features

• add message_type to MCPMessage trait (#26) (aca2336)

• implement ToMessage trait (#31) (435f18b)

  Details

  ToMessage Trait simplifies the construction of MCP messages, reducing the amount of code required:

  Example:

  Before Introducing the ToMessage trait

  async fn send_ping_request(ping_request: rust_mcp_schema::PingRequest) {
      let request_id = get_next_id();
  
      // construct a ServerMessage from the ping_request , with request_id
      let message = ServerMessage::Request(ServerJsonrpcRequest::new(
          request_id,
          RequestFromServer::ServerRequest(ServerRequest::PingRequest(ping_request)),
      ));
  
      // serialize message into a valid rpcJsonrpcMessage string
      let rpc_message_json_str = message.to_string();
  
      // send the ping request to the client
      tranport.send(rpc_message_json_str).await
  }

  After Introducing the ToMessage trait

  async fn send_ping_request(ping_request: rust_mcp_schema::PingRequest) {
       let request_id = get_next_id();
  
      // construct a ServerMessage from the ping_request , with request_id
      let message: ServerMessage = ping_request
          .to_message(request_id)
          .unwrap();
      
      // serialize message into a valid rpcJsonrpcMessage string
      let rpc_message_json_str = message.to_string();
  
      // send the ping request to the client
      tranport.send(rpc_message_json_str).await
  }

• introduce FromMessage trait (#30) (cc46100)

v0.1.6

0.1.6 (2025-02-17)

Features

• implement new utility functions (#24) (859b5db)

  New functions

  New functions provided by `MCPMessage` , available on `ClientMessage` and `ServerMessage`:

  • message.is_request() : Returns true if the message is a response type
  • message.is_response() : Returns true if the message is a request type
  • message.is_notification() : Returns true if the message is a notification type
  • message.is_error() : Returns true if the message represents an error
  • message.request_id() : Retrieves the request ID associated with the message, if applicable

Bug Fixes

• implemented Error trait for JsonrpcErrorError (#22) (753bd87)
• serializations to skip None Params (#25) (1f67654)

v0.1.5

0.1.5 (2025-02-15)

Features

• implement builder pattern for JsonrpcErrorError (#18) (71e63e5)

  Details

  Old Approach

  JsonrpcErrorError::new(
              schema_utils::RpcErrorCodes::method_not_found,
              "Method not found!".to_string(),
              None,
          );

  New Approach

  JsonrpcErrorError::method_not_found()

  • overriding the message and passing data:

  JsonrpcErrorError::method_not_found()
          .with_message("Method is not supported!".to_string())
          .with_data(Some(json!({"details": "No implementation found for this method."})))

Bug Fixes
