v2.0.1-alpha.5

What's New

You can now create Atlas clusters with multi-region configurations and Customer Managed Keys (CMK) encryption, pause and resume clusters, load sample data, and upgrade clusters directly through the MCP Server. When running aggregation pipelines that include write stages like $out or $merge, the server will now ask for explicit confirmation before proceeding, helping prevent accidental data modifications. Connection management has been made more explicit, sensitive information in configuration output is now redacted by default, and input validation has been tightened across tools so that unrecognized arguments are rejected rather than silently ignored.

v2.0.1-alpha.4

What's New

You can now create Atlas clusters with multi-region configurations and Customer-Managed Key (CMK) encryption directly through the MCP Server, alongside the existing ability to pause, resume, and upgrade clusters. Connection management has been overhauled with explicit connection handling that removes implicit session state, and a new maxSessions config option gives you control over how many sessions can be created. Sensitive information in configuration outputs and logs is now redacted by default, tool arguments are validated more strictly to reject unrecognized inputs, and MQL validation has been extended to cover projections in find, export, and explain operations.

v2.0.1-alpha.3

What's New

You can now create Atlas clusters with multi-region configurations and Customer Managed Keys (CMK) encryption directly through the MCP Server, and pause or resume existing clusters as needed. Connection management has been made more explicit, sensitive information in configuration outputs and logs is now redacted by default, and tool inputs are validated more strictly to reject unrecognized arguments. Atlas Search now supports $rerank in aggregation pipelines, and MQL validation has been expanded to include projections in find, export, and explain operations.

v2.0.0

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.

Full Changelog: v1.14.0...v2.0.0

v1.15.0-alpha.11

What's New

You can now create Atlas clusters directly from your AI assistant, including support for Customer-Managed Keys (CMK) encryption, as well as pause, resume, and upgrade existing clusters. New tools let you load sample data into a cluster, manage Atlas Stream Processing pipelines, and work with Atlas Search indexes including vector search and the new $rerank support for relevance-ranked results. Connection management has been improved with explicit connect and disconnect controls, sensitive information in configuration outputs is now redacted by default, and tool inputs are validated more strictly to catch errors before they reach your database.

v1.15.0-alpha.10

What's New

You can now create Atlas clusters with Customer Managed Keys (CMK) encryption, pause and resume clusters, upgrade clusters, and load sample data directly through the MCP Server. Connection management has been made more explicit, removing implicit session state so connections are clearer and more predictable. The server now enforces stricter input validation on tool arguments, redacts sensitive information in logs and config output by default, and adds $rerank support for Atlas Search pipelines.

Full Changelog: v1.15.0-alpha.9...v1.15.0-alpha.10

v1.15.0-alpha.9

What's New

Connection management has been overhauled with explicit connection handling, replacing the previous session-based approach, giving you more predictable and transparent control over database connections. Atlas search gets two notable upgrades: support for the $rerank stage in aggregation pipelines and a new on-demand tool for retrieving search stage rules, making it easier to build and tune advanced search queries. You can now create, pause, resume, and upgrade Atlas clusters, load sample data into a cluster, and manage Atlas Stream Processing — all directly through your AI assistant.

v1.15.0-alpha.8

What's New

Connection management has been overhauled with explicit connection controls, replacing the previous session-based approach, giving you more predictable and transparent control over your database connections. Atlas users can now create, upgrade, pause, resume, and load sample data into clusters directly through the assistant, and a new tool lets you search and rerank results using $rerank in Atlas Search pipelines. Sensitive information in configuration outputs and logs is now redacted by default, and tool inputs are validated more strictly so misconfigured or malformed requests are caught and reported clearly before any action is taken.
