v1.15.0-alpha.2

What's New

You can now pause, resume, upgrade, and create Atlas clusters directly through the AI assistant, as well as load sample data into a cluster to get started quickly. MQL validation has been expanded to cover projections in find, export, and explain operations, and sensitive information in configuration output and logs is now redacted by default for better security. A new maxSessions configuration option lets you control how many sessions the server creates, and you can optionally disable automatic IP access list creation when connecting to Atlas clusters.

mongodb-atlas-mcp-remote/v0.2.0

First pre-release of the mongodb-atlas-mcp-remote package. Not recommended for production usage yet.

v1.14.0-prerelease.2

What's New

You can now create, pause, resume, and upgrade Atlas clusters directly through the AI assistant, as well as load sample data into a cluster with a dedicated tool. Atlas Stream Processing is now supported with a full set of tools for managing streaming pipelines, and search and vector search indexes can be created, listed, and dropped. Tool responses across MongoDB, Atlas, and local tools now include structured content, making results easier for AI assistants to interpret and act on, and sensitive information in logs is redacted by default.

v1.14.0-prerelease.1

What's New

All tools now return structured response data alongside their text output, making it easier for AI assistants to reliably parse and use results without additional reformatting — this also improves resistance to prompt injection. A bug affecting local Atlas deployment creation has been fixed, where the tool would sometimes return before the deployment was fully ready, causing connection failures.

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.
