Save a block to the library

The save_library_entry MCP tool: save a block to the library.

save_library_entry · writes

REST: POST /v1/library/entries

#What the model reads

Saves one block of a trip, with everything inside it, to the library (Catalog → Blocks) so any trip can reuse it (insert_library_entry). Build or fix it in the trip first with the itinerary tools; blockId takes the ref get_itinerary prints. undo_change removes the entry again.

Permissions: catalog:write, trips:read. Undo: the result names a change id; undo_change reverts it.
