A lightweight, secure, and extensible MCP (Model Context Protocol) server for MySQL designed to bridge the gap between relational databases and large language models (LLMs).
I’m releasing a new open-source project: mysql-mcp-server, a lightweight server that connects MySQL to AI tools via the Model Context Protocol (MCP). It’s designed to make MySQL safely accessible to language models, structured, read-only, and fully auditable.
This project started out of a practical need: as LLMs become part of everyday development workflows, there’s growing interest in using them to explore database schemas, write queries, or inspect real data. But exposing production databases directly to AI tools is a risk, especially without guardrails.
mysql-mcp-server offers a simple, secure solution. It provides a minimal but powerful MCP server that speaks directly to MySQL, while enforcing safety, observability, and structure.
What it does
mysql-mcp-server allows tools that speak MC, such as Claude Desktop, to interact with MySQL in a controlled, read-only environment. It currently supports:
Listing databases, tables, and columns
Describing table schemas
Running parameterized SELECT queries with row limits
Running as either a local MCP-compatible binary or a remote REST API server
By default, it rejects any unsafe operations such as INSERT, UPDATE, or DROP. The goal is to make the server safe enough to be used locally or in shared environments without unintended side effects.
Why this matters
As more developers, analysts, and teams adopt LLMs for querying and documentation, there’s a gap between conversational interfaces and real database systems. Model Context Protocol helps bridge that gap by defining a set of safe, predictable tools that LLMs can use.
mysql-mcp-server brings that model to MySQL in a way that respects production safety while enabling exploration, inspection, and prototyping. It’s helpful in local development, devops workflows, support diagnostics, and even hybrid RAG scenarios when paired with a vector index.
Getting started
You can run it with Docker:
docker run -e MYSQL_DSN='user:pass@tcp(mysql-host:3306)/' \
-p 7788:7788 ghcr.io/askdba/mysql-mcp-server:latest
Semantic Search with SQL Simplicity and Operational Control
Introduction
Vector search is redefining how we work with unstructured and semantic data. Until recently, integrating it into traditional relational databases like MySQL required external services, extra infrastructure, or awkward workarounds. That changes with the MyVector plugin — a native vector indexing and search extension purpose-built for MySQL.
Whether you’re enhancing search for user-generated content, improving recommendation systems, or building AI-driven assistants, MyVector makes it possible to store, index, and search vector embeddings directly inside MySQL — with full support for SQL syntax, indexing, and filtering.
What Is MyVector?
The MyVector plugin adds native support for vector data types and approximate nearest neighbor (ANN) indexes in MySQL. It allows you to:
Define VECTOR(n) columns to store dense embeddings (e.g., 384-dim from BERT)
Index them using INDEX(column) VECTOR, which builds an HNSW-based structure
Run fast semantic queries using distance functions like L2_DISTANCE, COSINE_DISTANCE, and INNER_PRODUCT
Use full SQL syntax to filter, join, and paginate vector results alongside traditional columns
By leveraging HNSW, MyVector delivers millisecond-level ANN queries even with millions of rows — all from within MySQL.
Most importantly, it integrates directly into your existing MySQL setup—there is no new stack, no sync jobs, and no third-party dependencies.
Scoped Vector Search: The Real-World Requirement
In most production applications, you rarely want to search across all data. You need to scope vector comparisons to a subset — a single user’s data, a tenant’s records, or a relevant tag.
MyVector makes this easy by combining vector operations with standard SQL filters.
Under the Hood: HNSW and Query Performance
MyVector uses the HNSW algorithm for vector indexing. HNSW constructs a multi-layered proximity graph that enables extremely fast approximate nearest neighbor search with high recall. Key properties:
Logarithmic traversal through layers reduces search time
Dynamic index support: you can insert/update/delete vectors and reindex as needed
Configurable parameters like M and ef_search allow tuning for performance vs. accuracy

What’s Next
This post introduces the foundational concept of scoped vector search using MyVector and HNSW. In Part II, we’ll walk through practical schema design patterns, embedding workflows, and hybrid search strategies that combine traditional full-text matching with deep semantic understanding — using nothing but SQL.
I’m incredibly honored to share some exciting news—I’ve been recognized as an Oracle ACE Pro by Oracle!
This recognition is deeply meaningful to me, not just as a personal milestone but as a reflection of the ongoing work I’ve poured into the database community for over three decades. It’s also a reminder of how powerful open collaboration, curiosity, and mentorship can be in shaping both a career and a community.
What Is the Oracle ACE Program?
For those unfamiliar, the Oracle ACE Program recognizes individuals who are not only technically skilled but also passionate about sharing their knowledge with the wider community. It celebrates those who contribute through blogging, speaking, writing, mentoring, and engaging in forums or user groups.
The program has multiple tiers: ACE Associate, Oracle ACE, ACE Pro, and ACE Director. Each level reflects a growing commitment to community contribution and leadership. Being named an Oracle ACE Pro places me among a diverse, global group of technologists who are actively shaping the future of Oracle technologies—and open-source ecosystems alongside them.
From MySQL to ACE: A Journey Rooted in Community
My journey with data began over three decades ago, and it’s taken me across continents, companies, and countless events. My early days were steeped in MySQL—performance tuning, operations, scaling architectures—and I quickly discovered that the greatest impact didn’t come from just solving problems, but from sharing the solutions.
Since then, my path has included global roles in consulting, support, and engineering leadership. I’ve had the opportunity to speak at international conferences, publish books like the MySQL Cookbook (4th Edition), and contribute to countless community efforts in the MySQL and opensource database ecosystems.
Recognition such as Most Influential in the Database Community (Redgate 100) and MySQL Rockstar have meant a lot—but being named an Oracle ACE Pro is especially meaningful. It represents a bridge between the worlds of open source and enterprise and affirms that collaboration across ecosystems is not only possible—it’s essential.
What This Recognition Means to Me
This isn’t just about a title or a badge. To me, becoming an Oracle ACE Pro is about continuing the mission—to share what I’ve learned, amplify others doing amazing work, and give back to the communities that have shaped my path.
I’ve always believed that technical excellence must go hand in hand with generosity. Whether it’s mentoring a young DBA, helping a team scale their architecture, or writing about real-world database design challenges, the point has never been visibility—it’s always been about value.
And that’s what this recognition reflects: not just what I’ve done, but what I hope to keep doing for the next generation of data professionals.
Looking Ahead
This milestone energizes me even more to keep contributing—not just within the Oracle ecosystem but across the open-source database space. I’ll continue speaking at events, writing, mentoring, and building resources that help engineers build better, faster, and more resilient systems.
I’m also excited about promoting hybrid data architectures combining MySQL, opensource, and cloud-native technologies. This is where the industry is heading, and I’m committed to helping folks navigate that evolving landscape with clarity and confidence.
Gratitude and Community
I want to thank Oracle for running a program that not only recognizes technical contributions, but also community-driven spirit. And a heartfelt thank you to the MySQL community, open-source contributors, and peers I’ve had the privilege of working alongside over the years.
