qualityFacilitates interaction with a local MySQL database via a RESTful API, supporting database queries and real-time updates with integration for Cursor MCP services.

The MySQL MCP Server allows interaction with MySQL databases via JSON commands in a Docker container. You can:
- Execute read-only SQL queries (
query) - Test SQL write queries with automatic rollback (
test_execute) - List all tables in the database (
list_tables) - Describe the structure of a specific table (
describe_table)
Runs as a containerized service with special configurations for host connectivity, allowing MySQL database access from Docker environments with proper networking setup.
Uses environment variables stored in .env files for configuration management, particularly for sensitive database connection credentials.
Enables interaction with MySQL databases through read-only queries, schema exploration, and safe testing of write operations (with rollback). Provides tools for executing queries, listing tables, and describing table structures.
Implemented in TypeScript, providing type-safe database interactions with MySQL.
MySQL MCP Server
An MCP server for interacting with MySQL databases.
This server supports executing read-only queries (query) and write queries that are ultimately rolled back (test_execute).
Setup
Environment Variables
Add the following environment variables to ~/.mcp/.env:
Note:
host.docker.internalis a special DNS name for accessing host machine services from Docker containers. Use this setting when connecting to a MySQL server running on your host machine. If connecting to a different MySQL server, change to the appropriate hostname.
mcp.json Configuration
Usage
Starting the Server
Note: If you're using OrbStack,
host.docker.internalis automatically supported, so the--add-hostoption can be omitted. While Docker Desktop also typically supports this automatically, adding the--add-hostoption is recommended for better reliability.
Available Commands
1. Execute Read-only Query

2. Test Query Execution

Implementation Details
- Implemented in TypeScript
- Uses mysql2 package
- Runs as a Docker container
- Accepts JSON commands through standard input
- Returns JSON responses through standard output
- Uses
host.docker.internalto connect to host MySQL (compatible with both OrbStack and Docker Desktop)
Security Considerations
- Uses environment variables for sensitive information management
- SQL injection prevention is the implementer's responsibility
- Proper network configuration required for production use
- Appropriate firewall settings needed when connecting to host machine services
remote-capable server
The server can be hosted and run remotely because it primarily relies on remote services or has no dependency on the local environment.
Enables interaction with a MySQL database via JSON commands, supporting read-only queries, test execution of write queries, and table information retrieval through Docker.
