Navigate Neovim jump list: go back, forward, or list jumps
AI agents call vim_jump to retrieve information from Mcp Neovim Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool navigates the jump list in Neovim (moving the cursor back/forward or listing jumps). It only changes cursor position/view state within the editor, which is a non-destructive, non-persistent navigation action. No files are modified, no data is written or deleted. Severity is low as the blast radius of cursor navigation is minimal.
