Get players and coaches for a team
AI agents call teamsnap_get_roster to retrieve information from TeamSnap 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 roster information (players and coaches) from a TeamSnap team without modifying, deleting, or executing actions. It is a read operation. Severity is medium rather than low because roster data includes personal information about team members that could have privacy implications if exposed to an unauthorized agent, and could inform social engineering or targeting attacks.
