Flux Agent

flux-agent is a sophisticated multi-agent system built using the Strands Agents SDK. It features a "write-review-improve" feedback loop and integrates external tools via the Model Context Protocol (MCP).

Key Features

• Multi-Agent Orchestration: Uses a GraphBuilder to coordinate a writer, checker (quality evaluator), and finalizer.
• Feedback Loops: Implements a cycle where content is written, checked, and sent back for revision if it doesn't meet quality standards.
• MCP Integration: The writer agent can use external tools like mcp-server-fetch to retrieve real-time information from the web.
• Modular Tooling: Tools are abstracted into a dedicated app/tools directory for easy extensibility.
• Ollama Integration: Runs locally using Ollama (defaulting to llama3.1:latest).

Architecture

• app/workflow.py: Defines the graph structure, node transitions, and agent roles.
• app/quality_checker.py: A custom multi-agent node that determines if content is ready for finalization or needs another iteration.
• app/tools/:
  • web_tools.py: Manages the MCP connection to the fetch server.
  • __init__.py: Provides a central registry for all available tools.
• app/runner.py: A CLI interface for interacting with the workflow.

Getting Started

Prerequisites

1. Ollama: Ensure Ollama is installed and running with llama3.1 pulled:

   ollama pull llama3.1
   

2. uv: This project uses uv for lightning-fast Python package management. Install uv.

Installation

Clone the repository and install dependencies:

uv sync

Running the Demo

Launch the interactive CLI:

uv run main.py

Demo Options

• demo: Generates a haiku about programming loops (standard workflow test).
• tool: Fetches content from a URL and summarizes it (MCP tool test).
• exit: Gracefully close the application.

How it Works (MCP Tooling)

The writer agent is equipped with an MCPClient. When you ask for web content, the agent automatically:

1. Connects to the mcp-server-fetch via uvx.
2. Calls the fetch tool with the provided URL.
3. Receives the content and incorporates it into the response.
4. Sends the draft to the checker to start the review loop.
