**v1.29.0** — New `sync_desktop` / `sync-desktop`: incremental sync from Signal Desktop — fast on repeat calls, imports only new messages since the last run. Plus: incoming edits update the stored copy in-place, fixes for 500+ conversation crashes, improved store reliability.

What signal-cli is missing — and what signal-mcp adds

**No history.** signal-cli delivers a message and forgets it. signal-mcp stores every sent and received message — including messages sent from your phone — in a local SQLite database. It stays there. You can search it, browse it, export it, and ask Claude about it.

**No search.** signal-mcp adds an FTS5 full-text index. Find any message by keyword, filter by sender, page through results.

**No conversation view.** signal-cli has no concept of a thread. signal-mcp gives you paginated history per contact or group, unread counts, and last-message previews across all your chats.

**Raw phone numbers everywhere.** signal-mcp resolves `+12025551234` → `Anna Schmidt` in all output.

**Manual daemon management.** signal-mcp auto-starts the daemon on first use, re
