list_repository_tree_tool
AI agents call list_repository_tree_tool to retrieve information from MCP Gitlab without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves repository structure information without side effects. No creation, modification, deletion, or execution occurs. It is a standard read operation similar to 'ls' or 'tree' commands in version control systems. Confidence is 0.85 rather than higher because the description is empty, leaving minor ambiguity, but the name strongly indicates a read-only listing operation.
From the tool's definition Tool name 'list_repository_tree_tool' indicates listing/querying a repository's file tree structure. The 'list' verb and tree-browsing context suggest data retrieval with no modifications.
