Get information about a repl by its URL
AI agents call get_repl_by_url to retrieve information from Replit MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves metadata about an existing repl resource identified by URL. It has no side effects, does not execute code, does not modify state, and does not delete anything. It is a straightforward read operation with minimal risk even if misused by an AI agent, as it only exposes information that is already accessible via the URL.
From the tool's definition Tool name and description indicate retrieval only: 'Get information about a repl by its URL' with no modification, deletion, or execution semantics.
