### Description (declared)

# sql-performance-mcp 
 
[中文说明](README.zh-CN.md) 
 
[GitHub](https://github.com/shiro-4q/sql-performance-mcp) 
 
SQL performance analysis MCP server for MySQL, PostgreSQL, and SQL Server. 
 
The workflow is: 
 
1. User provides a SQL statement. 
2. The model calls `get_execution_plan` to fetch the execution plan. 
3. The model calls `get_table_schema` to fetch table columns. 
4. The model calls `get_indexes` to fetch table indexes. 
5. The model uses the `analyze_performance` prompt to assemble the final analysis prompt. 
 
## Tools 
 
### `get_execution_plan` 
 
Runs the database-appropriate execution plan command for a single SQL statement. 
 
Arguments: 
 
- `sql`: SQL statement to inspect. 
- `database`: optional database name. If omitted, the matching environment variable is used. 
- `database_type`: optional database type. Supported values are `mysql`, `postgresql`, and `sqlserver`. 
 
### `get_table_schema` 
 
Reads column metadata from the database's catalog views. 
 
Arguments: 
 
- `sql`: SQL statement to inspect. 
- `database`: optional database name. 
- `tables`: optional explicit table list, useful for complex SQL where table extraction is ambiguous. 
- `database_type`: optional database type. 
 
### `get_indexes` 
 
Reads index metadata from the database's catalog views. 
 
Arguments: 
 
- `sql`: SQL statement to inspect. 
- `database`: optional database name. 
- `tables`: optional explicit table list. 
- `database_type`: optional database type. 
 
### `analyze_performance` 
 
Builds a database-specific performance analysis prompt from: 
 
- `sql` 
- `execution_plan` 
- `schema` 
- `indexes` 
 
## Configuration 
 
Set database connection settings with environment variables: 
 
```powershell 
$env:MYSQL_HOST = "127.0.0.1" 
$env:MYSQL_PORT = "3306" 
$env:MYSQL_USER = "root" 
$env:MYSQL_PASSWORD = "password" 
$env:MYSQL_DATABASE = "app_db" 
``` 
 
Optional: 
 
```powershell 
$env:MYSQL_CHARSET = "utf8mb4" 
$env:MYSQL_CONNECT_TIMEOUT = "10" 
```
