The mysql_mcp_server allows interaction with MySQL databases, providing the following capabilities:
SQL Execution: Run various SQL commands (SELECT, INSERT, UPDATE) with role-based permission control (readonly, writer, admin)
Schema Management: Retrieve table structures and indexes, supporting multi-table queries
Chinese Language Support: Convert Chinese field names to pinyin initials and search tables by Chinese comments/descriptions
Database Analysis: Analyze database health (connections, transactions, running status), table locks, SQL execution plans, and index usage (redundant, poorly performing, or unused indexes)
Operational Modes: Supports both STDIO and Server-Sent Events (SSE) modes
Extensibility: Allows custom tool extensions and prompt template invocation for specific tasks
Enables configuration of MySQL database connection settings (host, port, user, password, database) through environment variables stored in .env files.
Allows executing SQL queries against MySQL databases, supporting multiple SQL statements, table name/field querying based on comments, SQL execution plan analysis, and Chinese to pinyin field conversion.
Click on "Install Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type
@followed by the MCP server name and your instructions, e.g., "@mysql_mcp_servershow me the table names that contain 'user' in their comments"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
mcp_mysql_server_pro
Introduction
mcp_mysql_server_pro is not just about MySQL CRUD operations, but also includes database anomaly analysis capabilities and makes it easy for developers to extend with custom tools.
Supports all Model Context Protocol (MCP) transfer modes (STDIO, SSE, Streamable Http)
Supports OAuth2.0
Supports multiple SQL execution, separated by ";"
Supports querying database table names and fields based on table comments
Supports SQL execution plan analysis
Supports Chinese field to pinyin conversion
Supports table lock analysis
Supports database health status analysis
Supports permission control with three roles: readonly, writer, and admin
"readonly": ["SELECT", "SHOW", "DESCRIBE", "EXPLAIN"], # Read-only permissions "writer": ["SELECT", "SHOW", "DESCRIBE", "EXPLAIN", "INSERT", "UPDATE", "DELETE"], # Read-write permissions "admin": ["SELECT", "SHOW", "DESCRIBE", "EXPLAIN", "INSERT", "UPDATE", "DELETE", "CREATE", "ALTER", "DROP", "TRUNCATE"] # Administrator permissionsSupports prompt template invocation

Usage Instructions
Installation and Configuration
Install Package
pip install mysql_mcp_server_proConfigure Environment Variables Create a
.envfile with the following content:
# MySQL Database Configuration
MYSQL_HOST=localhost
MYSQL_PORT=3306
MYSQL_USER=your_username
MYSQL_PASSWORD=your_password
MYSQL_DATABASE=your_database
# Optional, default is 'readonly'. Available values: readonly, writer, admin
MYSQL_ROLE=readonlyRun Service
# SSE mode
mysql_mcp_server_pro --mode sse --envfile /path/to/.env
## Streamable Http mode (default)
mysql_mcp_server_pro --envfile /path/to/.env
# Streamable Http oauth Authentication
mysql_mcp_server_pro --oauth true
mcp client
go to see see "Use uv to start the service" ^_^
Note:
The
.envfile should be placed in the directory where you run the command or use --envfile parameter to specify the pathYou can also set these variables directly in your environment
Make sure the database configuration is correct and can connect
Run with uvx, Client Configuration
This method can be used directly in MCP-supported clients, no need to download the source code. For example, Tongyi Qianwen plugin, trae editor, etc.

} Custom Tool Extensions
Add a new tool class in the handles package, inherit from BaseHandler, and implement get_tool_description and run_tool methods
Import the new tool in init.py to make it available in the server
OAuth2.0 Authentication
Start the authentication service. By default, it uses the built-in OAuth 2.0 password mode authentication. You can modify your own authentication service address in the env file.
uv run -m mysql_mcp_server_pro.server --oauth trueVisit the authentication service at http://localhost:3000/login. Default username and password are configured in the env file.
Copy the token and add it to the request headers, for example:
{
"mcpServers": {
"mysql_mcp_server_pro": {
"name": "mysql_mcp_server_pro",
"type": "streamableHttp",
"description": "",
"isActive": true,

}Examples
Create a new table and insert data, prompt format as follows:
# Task
Create an organizational structure table with the following structure: department name, department number, parent department, is valid.
# Requirements
- Table name: department

- Each field needs comments, table needs comment
- Generate 5 real data records after creation
Query data based on table comments, prompt as follows:
Search for data with Department name 'Executive Office' in Department organizational structure tableAnalyze slow SQL, prompt as follows:
select * from t_jcsjzx_hjkq_cd_xsz_sk xsz
left join t_jcsjzx_hjkq_jcd jcd on jcd.cddm = xsz.cddm
