What list_branches does on GitLab MCP Server

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

Why list_branches needs a policy

This tool retrieves and enumerates branches in a GitLab project. It performs no mutations, executions, or deletions—purely informational queries. The sibling tools (approve_merge_request, create_pipeline, cancel_pipeline) are more severe; this is clearly a read-only operation. Confidence is high despite the non-English description because the function name and repository context are unambiguous.

From the tool's definition Tool name 'list_branches' and description '列出專案的分支' (list project branches) indicate a retrieval operation that queries existing branch data without modification.
