SDK to facilitate the creation of AI agentic applications using Pydantic-AI, A2A, and MCP.

ALO PyAI SDK

SDK to facilitate the creation of AI agentic applications using Pydantic-AI, Agent-to-Agent (A2A) communication, and the Model Context Protocol (MCP).

Overview

This SDK provides tools and templates to quickly scaffold and manage AI agent projects. It leverages FastAPI for creating agent services and a central agent registry.

Features

• CLI for project initialization, component generation (agents, MCP clients), and configuration management.
• Standardized project structure.
• FastAPI-based agent services and registry.
• Integration with Pydantic-AI for agent logic.

Getting Started

1. Prerequisites:

   • Python 3.10+
   • pip and venv (or your preferred virtual environment tool)

2. Installation:

   pip install alo-pyai-sdk
   

   Alternatively, for development, clone the repository and install in editable mode:

   git clone https://your-repo-url/alo_pyai_sdk.git
   cd alo_pyai_sdk
   pip install -e .
   

3. Initialize a new project: This command creates a new project directory with the basic structure and an alo_config.yaml file.

   alo-pyai-sdk init my_new_ai_project
   cd my_new_ai_project
   

4. Configure LLM Providers: Add at least one LLM configuration to your alo_config.yaml. This is required for agents to function and for AI-assisted generation.

   # Example for OpenAI
   alo-pyai-sdk config llm add --name default_openai --provider openai --api-key "YOUR_OPENAI_API_KEY" --model-name "gpt-4o"
   
   # Example for Anthropic
   alo-pyai-sdk config llm add --name default_anthropic --provider anthropic --api-key "YOUR_ANTHROPIC_API_KEY" --model-name "claude-3-5-sonnet-latest"
   

   Replace "YOUR_..._API_KEY" with your actual API keys.

5. Start the Agent Registry (Optional but Recommended): The registry allows agents to discover each other.

   alo-pyai-sdk run registry
   

   By default, it runs on http://localhost:8000.

Usage

All commands are run via the alo-pyai-sdk CLI.

Project Initialization

• Initialize a new project in the current directory:

  alo-pyai-sdk init
  

• Initialize a new project in a specific directory:

  alo-pyai-sdk init path/to/your_project_name
  

Configuration Management (config)

• LLM Configurations:

  • Add a new LLM provider configuration:

    alo-pyai-sdk config llm add --name my_llm --provider openai --api-key "sk-..." --model-name "gpt-4o"
    

  • List all LLM configurations:

    alo-pyai-sdk config llm list
    

  • Remove an LLM configuration:

    alo-pyai-sdk config llm remove --name my_llm
    

  • Update an existing LLM configuration:

    alo-pyai-sdk config llm update --name my_llm --model-name "gpt-4o-mini"
    

• Registry Configuration:

  • Set the host and port for the agent registry:

    alo-pyai-sdk config registry --host 127.0.0.1 --port 8080
    

• MCP Client Configurations (in alo_config.yaml): When you generate an MCP client using alo-pyai-sdk generate mcp-client --name <client_name> ..., its configuration is automatically added to the mcp_clients section in your alo_config.yaml file. This section maps client names to their configurations, which include the generated module path and factory function name. Example of an automatically added entry:

  mcp_clients:
    your_client_name: # This is <client_name> provided to the generate command
      module: "mcp_clients.your_client_name"
      factory_function: "get_your_client_name_mcp_server"
      # Parameters used during generation (like type, url, command, args, tool_prefix)
      # are also stored for reference and potential future use by the factory.
      type: "stdio" 
      command: "deno"
      args:
        - "run"
        - "-A"
        - "jsr:@pydantic/mcp-run-python"
        - "stdio"
      tool_prefix: "py_runner"
      parameters: {} # You can manually add parameters here for the factory function if needed
  

  Agents generated by the SDK will automatically load and use MCP servers defined in this section. You can still manually edit this section if needed for advanced configurations or for MCP clients not generated by the SDK.

Agent Generation (generate)

• Generate a new agent service:

  alo-pyai-sdk generate agent --name MyStoryAgent --description "An agent that tells stories." --llm-config default_openai --output-type StoryOutput
  

  (This will create agents/my_story_agent/)

• Generate an agent with AI assistance for its definition:

  alo-pyai-sdk generate agent --name MyCodeHelper --ai-assisted --llm-config default_openai
  

  (You will be prompted for details about the agent's purpose, output, etc.)

• Generate an MCP client module:

  alo-pyai-sdk generate mcp-client --name python_stdio_runner --transport stdio --command "deno" --args "run,-A,jsr:@pydantic/mcp-run-python,stdio" --tool-prefix py_runner
  

  (This creates mcp_clients/python_stdio_runner.py)

Running Services (run)

• Run the Agent Registry:

  alo-pyai-sdk run registry
  

  (Uses configuration from alo_config.yaml)

• Run a specific Agent Service: (Ensure the registry is running if the agent is configured to register with it)

  # Example for an agent named 'MyStoryAgent'
  alo-pyai-sdk run agent MyStoryAgent 
  

  This command will look up the agent's port and other settings from alo_config.yaml (if previously generated and configured) or use defaults from the agent's local config.py. It will print the command to run the agent, typically:

  # Output from 'alo-pyai-sdk run agent MyStoryAgent':
  # Agent 'MyStoryAgent' will run using LLM config: default_openai
  # To start the agent, run the following command in your project directory:
  #    cd . 
  #    python -m uvicorn agents.my_story_agent.main:app --port 8001 --reload
  

  Then, you execute the printed python -m uvicorn ... command.

Provisioning (Future Feature)

• Commands for deploying and managing agents in different environments (e.g., Docker, cloud platforms).

  # alo-pyai-sdk provision ... (Details TBD)
