AI agents call get_todays_papers to retrieve information from Paper Scout MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or fetches today's AI research papers—a read-only operation with no side effects. It has no ability to modify, delete, or execute code. The low severity reflects minimal risk: the worst misuse would be retrieving irrelevant papers, which causes no harm. Confidence is high despite the truncated description, because the name and server context clearly indicate a simple data-retrieval function.
From the tool's definition Tool name 'get_todays_papers' and server description indicate retrieval of paper candidates from arXiv, Semantic Scholar, and Hugging Face Daily Papers.

{
"version": "1",
"default": "deny",
"tools": {
"get_todays_papers": {}
