INVOKE IMMEDIATELY when two IntelliJ MCPs are visible: mcp__intellij-index__* and mcp__intellij__*. These are NOT interchangeable — mcp__intellij-index__ supports auto-opening projects via project_path; mcp__intellij__ cannot. Always use mcp__intellij-index__ for code navigation. Never try mcp__intellij__ first and fall back. Also invoke for any IDE operation: rename, move file, find references, navigate to definition, type hierarchy, diagnostics.
