🔍 Multi-Agent Claim Verification System using Kognie API

An intelligent, multi-agent MCP server designed to verify claims using diverse AI models and real-time web research. This system combines the power of multiple language models with web search capabilities to provide comprehensive fact-checking and evidence analysis.

Visit : https://kognie.com/api to create a Kognie API key to gain access to multiple LLMs with one single account.

📽️ Demo video

We have used Github Copilot as the MCP client for our MCP server.

MCP client model : Claude 3.7 Sonnet

🎯 Purpose

In an era of information overload and misinformation, this system serves as a robust fact-checking tool that:

• Verifies claims using multiple AI perspectives
• Gathers real-time evidence from web sources
• Provides balanced analysis with supporting and contradicting evidence
• Makes informed decisions based on comprehensive data analysis
• Presents results in an intuitive, interactive web interface

🏗️ System Architecture

The system employs a hierarchical multi-agent architecture with specialized roles:

🤖 Agent Specifications

1. MultiLLM Verifier Agent

• Model: Claude-3.5-Sonnet (Anthropic)

• Role: Cross-model evidence analysis

• Responsibilities:

  • Coordinates multiple LLM perspectives
  • Runs parallel analysis across different AI models
  • Provides diverse viewpoints on claims

• Internal process: The system leverages three distinct AI models for comprehensive analysis:

  Model	Provider	Strengths
  GPT-4o-mini	Kognie API	Fast reasoning, general knowledge
  Gemini-2.0-Flash	Kognie API	Multimodal capabilities, recent training
  Open-Mistral-Nemo	Kognie API	European perspective, specialized domains

  Parallel Processing Benefits

  • Diverse Perspectives: Each model brings unique training and biases
  • Cross-Validation: Multiple viewpoints reduce single-model limitations
  • Speed: Asynchronous processing ensures rapid results
  • Robustness: System continues functioning even if one model fails

2. Web Evidence Retriever Agent

• Model: Claude-3.5-Sonnet (Anthropic)

• Role: Real-time information gathering

• Responsibilities:

  • Searches current web sources
  • Retrieves up-to-date information
  • Provides context-aware evidence

• Internal process:

  Real-Time Evidence Gathering

  • Bing Search API integration for current information
  • News source prioritization for recent developments
  • Automated query generation based on claim analysis
  • Evidence categorization (supporting vs. contradicting)

  Search Strategy

  1. Query Optimization: Transforms claims into effective search terms
  2. Source Diversification: Gathers information from multiple web sources
  3. Recency Prioritization: Focuses on current and relevant information
  4. Result Synthesis: Analyzes and structures findings

3. Boss Agent (Coordinator)

• Model: GPT-4o (OpenAI)
• Role: Final decision maker and coordinator
• Responsibilities:
  • Orchestrates other agents
  • Synthesizes evidence from multiple sources
  • Makes final verification decisions
  • Formats results in HTML for presentation

💻 User Interface

Interactive Web Interface (Gradio)

• Chat-based interaction for natural claim submission
• Real-time processing with progress indicators
• Collapsible analysis sections for detailed evidence review
• Color-coded results (Green for TRUE, Red for FALSE)
• Responsive design for various devices

Key Features

• Instant verification results
• Detailed evidence breakdown from each agent
• Interactive expandable sections for in-depth analysis
• Clean, professional presentation of complex data

🚀 Getting Started

Prerequisites

pip install gradio llama-index python-dotenv asyncio
