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 permissions - Supports prompt template invocation

Usage Instructions
Installation and Configuration
- Install Package
pip install mysql_mcp_server_pro
- Configure 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=readonly
- Run 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 path - You 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.
{
"mcpServers": {
"mysql": {
"command": "uvx",
"args": [
"--from",
"mysql_mcp_server_pro",
"mysql_mcp_server_pro",
"--mode",
"stdio"
],
"env": {
"MYSQL_HOST": "192.168.x.xxx",
"MYSQL_PORT": "3306",
"MYSQL_USER": "root",
"MYSQL_PASSWORD": "root",
"MYSQL_DATABASE": "a_llm",
"MYSQL_ROLE": "admin"
}
}
}
}
Local Development with Streamable Http mode
- Use uv to start the service
Add the following content to your mcp client tools, such as cursor, cline, etc.
mcp json as follows:
{
"mcpServers": {
"mysql_mcp_server_pro": {
"name": "mysql_mcp_server_pro",
"type": "streamableHttp",
"description": "",
"isActive": true,
"url": "http://localhost:3000/mcp/"
}
}
}
Modify the .env file content to update the database connection information with your database details:
# MySQL Database Configuration
MYSQL_HOST=192.168.xxx.xxx
MYSQL_PORT=3306
MYSQL_USER=root
MYSQL_PASSWORD=root
MYSQL_DATABASE=a_llm
MYSQL_ROLE=admin
Start commands:
# Download dependencies
uv sync
# Start
uv run -m mysql_mcp_server_pro.server
# Custom env file location
uv run -m mysql_mcp_server_pro.server --envfile /path/to/.env
# oauth Authentication
uv run -m mysql_mcp_server_pro.server --oauth true
Local Development with SSE Mode
- Use uv to start the service
Add the following content to your mcp client tools, such as cursor, cline, etc.

mcp json as follows:
{
"mcpServers": {
"operateMysql": {
"isActive": true,
"name": "operateMysql",
"command": "uv",
"args": [
"--directory",

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 true
-
Visit 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,
"url": "http://localhost:3000/mcp/",
"headers": {
"authorization": "bearer TOKEN_VALUE"
}
}
}
}
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
- Common fields need indexes
- 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 table
- Analyze 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
Based on current index situation, review execution plan and provide optimization suggestions in markdown format, including table index status, execution details, and optimization recommendations
- Analyze SQL deadlock issues, prompt as follows:
update t_admin_rms_zzjg set sfyx = '0' where xh = '1' is stuck, please analyze the cause
- Analyze the health status prompt as follows
Check the current health status of MySQL
