WHAT IT DOES

What get_project_branches does on GitLab MCP Server

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

RISK

Why get_project_branches is rated Low

This tool retrieves information about branches within a GitLab project. It performs a read-only query of existing data without creating, modifying, deleting, or executing any operations. The blast radius is minimal as it only exposes project branch metadata that is typically visible to users with repository access.

From the tool's definition Tool name is 'get_project_branches' and description states 'Gets all branches in a project' — a query operation with no modification or side effects.

get_project_branches Allowed

get_project_branches is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
