• xmp4_grep

  Server-side regex text search over indexed project source files. Free tier: requires file_path (single file). Premium tier (XMP4_PREMIUM_GREP_WALK=true): allows file_glob multi-file walk. Prefer xmp4_tests_for/xmp4_usages for SCIP symbols — grep is for text not indexed (comments,

• xmp4_guide

  Usage guide for xmp4 tools — read this first to learn the correct workflow

• xmp4_hierarchy

  Get type hierarchy (base, interfaces, derived) for a symbol in a project.

• xmp4_info

• xmp4_usages

• xmp4_view

  Read a raw file excerpt from an indexed project by line range. Use after xmp4_search/xmp4_outline locates the region of interest, or to expand a truncated xmp4_source snippet. Hard cap of 500 lines per call.
