Fetch a specific Reddit post by URL. Returns the post data and up to 100 comments (flat, no scores).
AI agents call scrape_post to retrieve information from Reddit Scraper without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves and returns publicly available Reddit post data and comments. It does not modify, delete, or create any data. Storing locally is a side effect of the server's design, but the tool action itself is a read/fetch operation. Misuse potential is low since it only reads public Reddit content.
From the tool's definition 'Fetch a specific Reddit post by URL. Returns the post data and up to 100 comments (flat, no scores).'
