Chapter 6 : AI Agents

Build AI Agents​

  • Build AI Agents with No-code and Customize & Extend to complete your use case.
  • Use AI Agents in workflows or as chat.

Prerequisite​

AI Agents Building​

Jumpstart development with AI Agents Building code based on common patterns described in Anthropic's research paper Building Effective Agents.

The agentic system's code model agentic flows in terms of:

  • Multi-LLM Workflows
    • Prompt-Chaining: Decomposes a task into sequential subtasks, where each step builds on previous results.
    • Parallelization: Distributes independent subtasks across multiple LLMs for concurrent processing.

Also available:

  • Chat Agent with access to MCP Tools
    • A simple command-line chat application with access to EasyManage MCP Server Tools available, to chat with AI models.

AI Agents - Spring Java​

AI Agent emagent​

  • Agentic System Workflows with all supported agentic patterns, with access to MCP Tools
  • Low-code customize to build AI solutions

AI Agent emchat​

  • Chat Agent with access to MCP Tools

Locating Agent Projects​

info
  • AI Agent - Spring Java is built along with Backend & MCP spring-java.
  • Project Location in downloaded dir is at e.g.
    • EmGenDir_JohnDoe_WS_51069\WS_51069\agent\spring-java\emagent
  • Chat Agent with access to MCP Tools is at e.g.
    • EmGenDir_JohnDoe_WS_51069\WS_51069\agent\spring-java\emchat

Run Builds and Explore​

tip

AI Agents invoke MCP Layer which Connects to API Layer, REST or GraphQL. So please configure and run destination API Layer first. Then build MCP Layer.

AI Agent Project Build & Run​

info

Please review Prerequisites in emagent\README.md

  • Make sure emmcp project maven artifact is available for Agent project
  • via building emmcp with mvn clean install
  • Go to Project Location in downloaded dir is at e.g.
    • cd EmGenDir_JohnDoe_WS_51069\WS_51069\agent\spring-java\emagent
  • Set env var: OPENAI_API_KEY

  1. Build the project:

    ./mvnw clean install

  2. Run the application:

    ./mvnw spring-boot:run

AI Agent Example Runs​

• Agent Util Examples​

MCP Tool Calling Pre-configured​

AI Agent to MCP Tool calling is pre-configured and available via util functions.

  • Please view example Util functions in e.g. product table util at
    • emagent\src\main\java\com\example\emagent\app\Product\ProductEmAgentUtil.java

Below functions are made available for each table, developers can choose from them and use in workflows as needed.

    private String prompt_get_table_data_all =  "get table data all from product table"; 
    public List<Product> get_table_data_all_product()
    private String get_table_data_paged_product =  "get table data as pages from product table for page 1 size 10"; 
    public List<Product> get_table_data_paged_product()
    //private String get_table_data_queried_product =  "get table data queried and sorted as per parameter strings as pages from product table queried as \" productId is not null \" sorted by \" productId desc \" with 1 page size 3 "; 
    private String get_table_data_queried_product =  "get table data as pages from product table queried as \" productId is not null \" sorted by \" productId desc \" with 1 page size 3 "; 
    public List<Product> get_table_data_queried_product()
    private String get_table_data_by_key_product =  "get table data by key column from product table for key 1 "; 
    public List<Product> get_table_data_by_key_product()

    private String create_table_data_record_product =  "create table data record in product table with values as below "; 
    public Long create_table_data_record_product()
 
    private String update_table_data_record_product =  "update table data record in product table with values as below  "; 
    public Long update_table_data_record_product()

    private String delete_table_data_record_product =  "delete table data record in product table with value 1  "; 
    public long delete_table_data_record_product()
 
    //default - get data as String 
    public String agenticUtil()
