🔧 Usage

API Endpoints

• GET / - Health check endpoint
• POST /mcp/hello - Test endpoint for verifying connectivity
• POST /mcp/reddit - Generate digests by topic (ai, cybersecurity, tech update, etc.)
• POST /mcp/reddit/subreddit - Generate digests from custom subreddits

Example Requests

Generate a digest by topic:

curl -X POST "http://localhost:8000/mcp/reddit" \
  -H "Content-Type: application/json" \
  -d '{"input": "ai"}'

Generate a digest for specific subreddits:

curl -X POST "http://localhost:8000/mcp/reddit/subreddit" \
  -H "Content-Type: application/json" \
  -d '{"input": "MachineLearning, artificial, IndiaTech"}'

⚙️ Configuration

Scheduled Digests

The system is configured to run scheduled digests. Edit scheduler.py to adjust the timing:

# For production (runs daily at 9 AM)
scheduler.add_job(scheduled_reddit_digest, 'cron', hour=9, minute=0)

# For testing (runs every minute)
scheduler.add_job(scheduled_reddit_digest, 'interval', minutes=1)

Topic Mappings

Default topic-to-subreddit mappings are defined in reddit_fetcher.py. Add or modify mappings as needed:

TOPIC_SUBREDDITS = {
    "tech update": ["technology", "technews", "IndiaTech", "developersIndia"],
    "ai": ["MachineLearning", "ArtificialIntelligence", "Singularity", "artificial"],
    # Add new mappings here
}
