MySQL Schema MCP Server

MySQL Schema MCP Server is an MCP server that retrieves database schema definitions and structural metadata from MySQL instances using the FastMCP framework. It connects directly to a target MySQL database or its information schema using standard database credentials, exposing core schema details to AI clients and autonomous agents. Software engineers, database administrators, and backend developers use this server to inspect table layouts, review column data types, verify indexing strategies, and analyze foreign key relationships without manually writing SQL queries. By integrating with MCP-compatible clients, it enables language models to accurately understand the structural context of relational databases during tasks such as code generation, query drafting, and schema documentation. The server supports local Python environments via uv or pip, as well as containerized deployments using Docker, making it simple to run across various development workflows.

How to install and configure MySQL Schema MCP Server

1. Clone the repository: bash git clone https://github.com/Shion-Serizawa/mcp-first cd mcp-first 2. Install dependencies using uv or pip: bash uv venv uv pip install -r requirements.txt 3. Create a .env file based on .env.example and supply your database credentials (MYSQL_HOST, MYSQL_PORT, MYSQL_USER, MYSQL_PASSWORD, MYSQL_DATABASE). 4. Add the server to your MCP client configuration (such as Claude Desktop) under mcpServers: json { "mcpServers": { "mysql-schema": { "command": "python", "args": ["main.py"], "cwd": "/path/to/mcp-first", "alwaysAllow": ["databases", "tables", "schema", "indexes", "foreign_keys"] } } } 5. Restart your MCP client to load the schema tools.

What you can do with MySQL Schema MCP Server

• Listing available MySQL databases and tables directly inside an AI coding assistant to plan migrations or queries. - Inspecting column names, nullability, and data types for multiple tables simultaneously to generate accurate ORM models. - Reviewing table index structures to assist developers and AI assistants in diagnosing query performance bottlenecks. - Examining foreign key constraints and relations between MySQL tables to understand relational dependencies and join logic.
