WHAT IT DOES

What mcp_get_collection_stats does on Mongo-MCP

AI agents call mcp_get_collection_stats to retrieve information from Mongo-MCP without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why mcp_get_collection_stats is rated Low

Despite the empty description, the tool name strongly suggests it retrieves statistics about a MongoDB collection—a read operation with no side effects. The context of the server supporting 'server monitoring' reinforces this classification. Lower confidence (0.85) due to missing description, but the naming pattern and operational context are clear enough to classify with reasonable certainty as a Read operation.

From the tool's definition Tool name 'mcp_get_collection_stats' indicates retrieval of collection statistics and monitoring data. The server description mentions 'comprehensive server monitoring' as a capability, and this tool aligns with that read-only monitoring function.
