mcp-v0.18.0

What's New

• delete_blocks action for agents — Agents can now delete entire blocks—list items, paragraphs, headings—in a single call, with bullets and numbering removed automatically. Unlike delete_text, which removes content but leaves the block structure behind, delete_blocks cleans up the entire block and supports tracked changes with changeMode:'tracked'.

Fixes

• Tracked changes preserve metadata across word boundaries — Fixed tracked insertions and deletions losing their change metadata when a run begins with a non-breaking hyphen, which previously split the revision at the word boundary.
• Tracked deletions work correctly around cross-reference fields — Fixed tracked deletions being lost during import and export when the deleted region contains cross-reference fields, which previously caused the field to reappear as untracked content.
• Tracked change chains merge correctly across run boundaries — Fixed tracked changes split by word run boundaries now merge into a single unified revision instead of appearing as separate tracked changes.
• Locked content controls survive block wrapping — Fixed locked content controls being removed when their containing blocks are wrapped or repositioned.
