replace_text_in_block is the most ergonomic edit tool the MCP has – no position math, just find-and-replace. But it's limited to text within a single paragraph. The moment the target spans a line break, you're back to get_note_outline + replace_range, which is five times the work for what should be a small edit.

Extending it to work across adjacent blocks – or at least adjacent list items – would cover most real-world editing cases without changing the simple API surface.
