New internal tool-name lists help detect web-search-capable dynamic MCP server configs

What

Claude Code gained two new internal lists of tool names: one covering search and lookup tools like image_search, web_search, web_search_fast, web_fetch, and several display-card tools, and another covering tools like image_annotation, generate_image, conversation_search, and recent_chats. A new helper function checks whether any dynamically configured HTTP MCP (Model Context Protocol, a way of connecting external tool servers) server matches a given tool name and scope or type.

Why

This is internal infrastructure for recognizing when a dynamically configured MCP server provides web-search-like capabilities, though the finding doesn't say what feature consumes this detection.
