MindsDB Release Notes - September 2025

This month’s release is packed with powerful improvements aimed at making MindsDB even more intuitive, efficient, and reliable—whether you're building with Agents, querying Knowledge Bases, or scaling your deployment.

From simplified API configurations and unified server architecture to enhanced memory controls and expanded MySQL support, this update reflects our ongoing mission to make AI-native data workflows easier for everyone. We've also rolled out important security enhancements, cleaned up legacy dependencies, and improved the MindsDB user experience across the board.

Let’s dive into what’s new in the September release.

MindsDB Setup

This release brings several improvements under the hood to make your MindsDB experience smoother, leaner, and easier to manage.

MindsDB no longer uses pidfile inside Docker containers. This change reduces unnecessary system processes and simplifies operations, helping improve overall performance and stability. The HTTP, MCP, and A2A servers have been merged into a single server process, providing a more unified server architecture. This reduces system complexity and code duplication, making MindsDB more efficient and easier to maintain.

We also introduce cleaner configurations for MCP & A2A. Configuration options and environment variables specifically for the MCP and A2A APIs have been removed. These APIs are now served under the same port as MindsDB (default: 47334) at the paths /mcp/ and /a2a/. This simplifies setup and makes it easier to host behind a reverse proxy—no need for extra ports or environment variables.

Authentication Improvements have also been made. MindsDB now uses bearer token authentication instead of cookie-based Flask sessions.If you're using the MindsDB UI, nothing changes—you’ll continue to log in as usual. However, if you're connecting programmatically with authentication enabled, you'll now need to update your code to use the bearer token returned by the /api/login endpoint.

These changes pave the way for a more secure, consistent, and scalable MindsDB experience.

Knowledge Bases

We’ve made improvements to how model defaults are handled in MindsDB. Now, default model settings are stored directly within the Knowledge Base itself. This update ensures that when you're building models, they follow a more stable, consistent, and reliable configuration—reducing potential discrepancies or mismatches during setup. It also makes it easier to reproduce or audit model behavior, especially across teams or environments.

In addition, we’ve expanded the filtering capabilities inside the Knowledge Base by introducing support for the greater than (>) operator in relevance filters. This enhancement allows you to fine-tune search results more precisely, especially when working with numeric values like confidence scores, timestamps, or custom metadata fields. Whether you're narrowing down high-relevance answers or segmenting by thresholds, this change makes search and retrieval more practical and flexible.

Integrations

A new pwd command has been added to help users easily view the current folder path, making navigation simpler and more intuitive.We've removed support for the MongoDB API in this release to streamline the codebase, as it was rarely used and no longer maintained.

Support for the Bedrock provider has been added to Agents, improving integration flexibility across environments. We fixed a VLLM connection error message for clearer troubleshooting and also resolved issues with Knowledge Base integration tests, leading to improved test reliability.

Bug Fixes & Improvements

We’ve made several improvements in this release focused on security, performance, and usability.

To strengthen security, we resolved issues with environment secrets and fixed a CodeQL warning related to SSL. These changes help protect sensitive data and enhance system integrity.Performance has also been optimized: we've introduced safeguards to limit memory usage spikes, helping prevent unexpected crashes under heavy load.

The MindsDB OSS Agent now has better management of conversation history, ensuring more accurate tracking. Additionally, we fixed issues with how Agents interact with Knowledge Bases, enabling smoother and more reliable integration.

We’ve addressed multiple quality-of-life fixes:

• Testing deprecation warnings were resolved to keep MindsDB aligned with modern best practices.

• File uploads now handle file names more reliably, reducing user-facing errors.
  The GUI auto-update feature is now working as intended, improving ease of use.

• MindsDB is now fully compatible with Python 3.13, expanding support for more environments.

• A new environment variable lets users run MindsDB without the GUI, offering more flexibility for headless or server-based deployments.

• Confusion around the config path has been resolved, simplifying setup for new and existing users.

Lastly, we’ve included several general fixes and performance enhancements to ensure MindsDB continues to run efficiently and reliably.

Documentation

We’ve made several helpful updates to the MindsDB documentation to make it easier to understand and use. The documentation for the llm() function has been improved, so users can now get a clearer idea of how it works. We’ve also added information about new functions, which gives users a broader view of what MindsDB can do.

We included details about a new environment variable for managing PID File, which helps users handle process settings more easily. Additionally, we added a list of date-time functions and list commands to help users find what they need faster.

Some outdated information has been cleaned up as well. Documentation for the MongoDB API has been removed, since it’s no longer supported. We also removed AWS references to reflect the current state of the product.

Other important sections like Knowledge Bases, Agents, APIs, and authentication have been updated with the latest guidance. We’ve made the naming of objects in the docs more consistent, which should make things easier to follow. Lastly, we updated our Mintlify docs dependency to improve reliability and keep everything running smoothly.

SQL Operations

We’ve added support for new MySQL datetime functions, giving you more flexibility to write advanced and precise time-based queries.

In this update, we also fixed the SQL renderer for the INTERVAL statement, making SQL rendering more accurate and efficient when working with time intervals.

OS GUI

MindsDB has added a new pop-up to accept our Terms & Conditions. We have also added an option to switch off MindsDB’s Telemetry in the Settings. You can easily request to upgrade to our Minds Enterprise solution by navigating to the sidebar and selecting ‘Upgrade’ or clicking on the MindsDB logo.

All of our verified integrations have been added to our GUI. We have also added a toolbar to easily access Settings, Integrations and Report a Bug feature.

Our GUI’s sidebar has been improved with better UI elements for you to seamlessly navigate through tabs.Performance and accessibility in our themes, Light and Dark mode, has been improved. You can now add your own custom models or BYOM by navigating to the models section in treeview.

That wraps up our September updates! Check out MindsDB’s full Release Notes. We’re constantly working to make MindsDB faster, smarter, and easier to use—whether you’re building with Agents, scaling with Knowledge Bases, or integrating into your existing stack.
