开发要求

  • Java 21+

运行步骤

  1. 编译项目:
./mvnw clean package
  1. SSE 模式下运行服务器:
java -jar target/rte-mcp-server-0.0.1-SNAPSHOT.jar
  1. STDIO 模式下运行服务器:
java -jar -Dspring.ai.mcp.server.stdio=true rte-mcp-server-0.0.1-SNAPSHOT.jar

RteUtils工具类

本项目旨在易于扩展。你可以通过使用 RteUtils 类添加自己的MCP工具。

同时,需要以 yaml 格式定义RTE连接参数和RTE流程。

RteUtils 实现了以下方法:

  • static RteProtocolClient connect(RteConfig config):使用提供的 yaml 文件连接到RTE服务器。
  • static String executeSteps(RteProtocolClient client, List<RteStep> steps):在RTE服务器上执行提供的步骤,并使用提供的 yaml 文件将屏幕结果作为字符串返回。

作为MCP工具公开的方法应使用 @Tool 注解,类应使用 @Services 注解,如下例所示:

@Service
public class RteServiceLoginTool implements RteTool {

  private static final Logger logger = LoggerFactory.getLogger(RteServiceLoginTool.class);

  @Tool(description = "Execute an RTE transaction in a given server", name = "TN5250 Login")
  public String executeRteTransaction(String server, int port) {
    try {
      RteFlow flow = RteYamlLoader.load("/flow.yaml");
      RteProtocolClient client = RteTool.connect(flow.getConfig(), server, port);
      return RteTool.executeSteps(client, flow.getSteps());
    } catch (IOException | RteIOException | InterruptedException | TimeoutException e) {
      logger.error("Error executing RTE flow", e);
      return "Error executing RTE flow: " + e.getMessage();
    }
  }
}

yaml 文件定义了连接参数和在RTE服务器上执行的步骤。该 yaml 文件应具有以下结构:

config:
  server: localhost
  port: 2324
  protocol: TN5250
  terminalType: 'IBM-3477-FC: 27x132'
  sslType: None

steps:
  - actions:
      - label: User
        input: TESTUSR
      - label: Password
        input: TESTPSW
    attentionKey: ENTER

可以在 yaml 文件中定义任意数量的步骤。 | 属性 | 详情 | |------|------| | 服务器地址 | 连接到RTE服务器的服务器地址。 | | 端口 | 连接到RTE服务器的端口。 | | 协议 | 支持的协议有 TN5250TN3270VT420。 | | 终端类型 | 以下表格显示了每种协议支持的终端类型:

Runtime guide

Hosted runtime

Hosted servers run from a provider-managed environment. You usually connect the MCP client to the hosted endpoint or follow the provider's authorization flow, without keeping a local process alive

  1. Open provider connection page
  2. Authorize or copy endpoint
  3. Connect from your MCP client
terminal

Local runtime / other methods

Local servers run on your own machine or infrastructure. You normally copy the server_config into your MCP client, install the required package, and provide env variables from env_schema when needed

  1. Copy server_config
  2. Install required package
  3. Fill env variables and restart client
