Get help and information about available V MCP server tools.
AI agents call get_v_help to retrieve information from V Language MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves informational content (help text, tool descriptions, available functions) without modifying, executing, or deleting anything. It is a straightforward read operation with no side effects. The low severity reflects that misuse would only expose documentation, not cause harm.
From the tool's definition Tool name 'get_v_help' and description 'Get help and information about available V MCP server tools' indicate a query operation that retrieves and presents documentation or metadata about available tools.
