Universal database MCP server for MySQL, PostgreSQL, SQL Server, MariaDB,Oracle

Hi! I'd like to share the tool that I just worked. If you are using Anthropic's Claude AI and Database, this might be helpful to you.

SmartDB is a universal database gateway that implements the Model Context Protocol (MCP) server interface. This gateway allows MCP-compatible clients to connect and explore different databases.

Compared to similar products, SmartDB not only provides basic database connection and exploration capabilities but also adds advanced features such as OAuth 2.0 authentication , health checks, SQL optimization, and index health detection, making database management and maintenance more secure and intelligent.

SmartDB’s “Superpowers”: Seven Core Advantages

1. Multi-Database Support: One Tool for All Major Databases
   SmartDB supports four major database systems, covering a wide range of versions:
   MySQL: 5.6+ (including MariaDB 10+)
   PostgreSQL: 9.6+ (including YMatrix)
   Oracle: 12c+
   SQL Server: 2012+
   No matter which database your enterprise uses, SmartDB has you covered—no more switching tools for different databases.

2. Connection Pool Management: Boost Performance, Save Resources
   Database connections are a common performance bottleneck. SmartDB uses an efficient connection pool mechanism to reuse connections and reduce overhead, resulting in faster query responses and lower server load.

3. Health Checks & Monitoring: Your Database’s “Personal Doctor”
   SmartDB can monitor database status in real time, automatically detect anomalies (such as connection interruptions or slow queries), and generate professional diagnostic reports—transforming DBAs from “firefighters” to “prevention experts.”

4. SQL Execution & Optimization: From “Writing SQL” to “Smart Optimization”
   The built-in sql_optimize tool analyzes execution plans and table structures, automatically providing optimization suggestions (e.g., “Create an index on the user_id field”) to boost SQL performance!

5. Table Structure & Index Management: Instantly Map Your Database
   With the get_table_desc and get_table_index tools, developers can quickly query table structures and index information, supporting multi-table queries and even Chinese/English table name searches—like a CT scanner for your database.

6. OAuth Security Authentication: A “Golden Shield” for Data Security
   SmartDB integrates OAuth 2.0 authentication, supporting role-based access control (read-only, read-write, admin), ensuring only authorized users can access data and eliminating leakage risks at the source.

7. Extensible Architecture: As Flexible as LEGO
   Modular design makes SmartDB easy to extend—whether adding support for new databases or customizing features, it’s a breeze.

Let me know what you think of it. Thanks!
