What's New
You can now create Atlas clusters with multi-region configurations and Customer-Managed Key (CMK) encryption directly through the AI assistant, alongside new tools to pause, resume, and upgrade existing clusters. Atlas search now supports $rerank in aggregation pipelines and input validation has also been tightened across several tools, so misconfigured requests are caught and reported earlier rather than producing unexpected results.
Additionally, database operations now require an explicit connection id. Connect tools such as connect, atlas-connect-cluster, and atlas-local-connect-deployment have been updated to return a connection id, while the pre-configured connection is using the hardcoded preconfigured id. LLMs need to then pass that connection id to all database operations instead of relying on executing against the last connection.
