Get the combined status for a commit
AI agents call get_combined_status to retrieve information from Mcp Github without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

The 'get' verb and retrieval nature confirm Read category. Severity is low because unauthorized access to commit status poses minimal risk compared to write/destructive operations.
