v1.14.0-prerelease.0

What's New

Improved request tracing is now built into the MongoDB MCP Server, with request IDs automatically passed through Atlas API calls and included in logs, making it easier to diagnose issues by correlating server activity with specific requests. A new evaluation framework has also been added internally to help ensure the accuracy and reliability of MCP tool responses over time.

v1.13.0

What's New

You can now pause and resume Atlas clusters directly through the MCP Server, and quickly load sample datasets into a cluster to get started with realistic data. Server-side JavaScript functions ($where, $function, and $accumulator) are now disabled by default to prevent unintended behavior, though this can be configured if needed. A bug fix also ensures that renaming a collection with dropTarget: true is correctly blocked when destructive operations are disabled.

v1.12.0

What's New

You can now create MongoDB Atlas clusters directly from your AI assistant using the new create cluster capability. It supports M10–M80 replica sets and single-shard clusters, automatically selecting a sensible instance size based on your existing project clusters, and returns immediately so you can continue working while the cluster provisions in the background.

v1.11.0

What's New

When connecting to Atlas Free or Flex tier clusters, the server now automatically checks for active resource alerts and surfaces a recommendation to upgrade your cluster when relevant thresholds are being exceeded. You can also now upgrade Free or Flex clusters directly to a higher tier (Free→Flex, Free→M10, or Flex→M10) using the new atlas-upgrade-cluster tool. Additionally, a new database-level aggregation tool has been added, and the setup command now includes an option to download MongoDB Agent Skills alongside the MCP server configuration.
