• verify_claim(): Evaluates the accuracy of identified claims based on multiple data sources.
• search_news(): Sift through news articles to find relevant information.
• analyze_source(): Analyzes source reliability for more accurate assessments.

External APIs

• Google Gemini API: Enables AI-based claim extraction and verification.
• NewsAPI: Provides access to a wide range of news feeds for context and trending topics.
• Wikipedia API: Offers detailed background on various subjects to verify factual claims.
• Reddit API: Tracks social media interactions related to misinformation.
• Fact Check API: Leverages third-party fact-checking resources.

🚀 Getting Started with Installation

Prerequisites

• Python 3.10 or higher.
• API keys for external services (Google Gemini, NewsAPI, Reddit API).

Installation with UV (Recommended)

Follow these steps to install TruthLens using the Universal Virtual Environment (UV):

Step 1: Install UV

pip install uv

Step 2: Clone and Navigate to Repository

git clone <repository-url>
cd MCP\ Build

Step 3: Create and Activate Virtual Environment

uv venv
# On Windows:
.venv\Scripts\activate
# On macOS/Linux:
source .venv/bin/activate

Step 4: Install Dependencies

uv pip install -r requirements.txt

Step 5: Set Up API Keys

Create a new file named .env in the root directory and add your API keys using the following format:

# TruthLens API Keys

GEMINI_API_KEY=your_gemini_api_key_here
NEWSAPI_KEY=your_newsapi_key_here
REDDIT_CLIENT_ID=your_reddit_client_id_here
REDDIT_CLIENT_SECRET=your_reddit_client_secret_here
REDDIT_USER_AGENT=TruthLens/0.1 (by /u/YourUsername)

Important Notes:

• Ensure you have the minimum required API keys for proper functionality.
• Never commit your .env file to version control.

Step 6: Run the Server

python run_server.py

Alternative Installation with pip

If UV is not installed, you can use pip:

python -m venv .venv
# On Windows:
.venv\Scripts\activate
# On macOS/Linux:
source .venv/bin/activate
pip install -r requirements.txt
python run_server.py

💡 Key Use Cases in AI Workflows

Real-time Claim Validation for News Articles

• Scenario: A news article claims that "5G technology is harmful to human health."
• Implementation:

  truthlens://truthlens/ingest_url(url="https://example.com/article")
  truthlens://truthlens/extract_claims(text="5G technology...")
  truthlens://truthlens/verify_claim(claim_text="5G technology is harmful to human health.")
  

• Outcome: The server returns evidence and a confidence score indicating the claim’s veracity.

Automated Misinformation Monitoring for Social Media

• Scenario: A community claims on Twitter that "Vaccines cause autism."
• Implementation:

  truthlens://truthlens/ingest_url(url="https://twitter.com/community/status/123456")
  truthlens://truthlens/extract_claims(text="vaccines...autism")
  truthlens://truthlens/verify_claim(claim_text="Vaccines cause autism.")
  

• Outcome: The server detects the claim, verifies it using reliable sources, and alerts the MC client with evidence supporting its accuracy.
