Overview

What is MySQL MCP Server?

MySQL MCP Server is a Model Context Protocol (MCP) server that enables MCP clients (such as AI assistants) to query and modify data in a MySQL database. It connects to a user-configured MySQL instance and exposes tools for executing SQL statements over standard input/output (stdio).

How to use MySQL MCP Server?

Install dependencies with npm install, build the TypeScript code with npm run build, then run mysql-server (if linked globally) or node build/index.js. Configure connection via environment variables: MYSQL_HOST, MYSQL_USER, MYSQL_PASSWORD, MYSQL_DATABASE (required), and optionally MYSQL_PORT (default 3306). Set MYSQL_ALLOW_WRITE_OPS=true to enable write tools (insert, update, delete); otherwise only read-only queries are allowed.

Key features of MySQL MCP Server

  • Connects to MySQL using standard connection parameters.
  • Provides MCP tools for executing SQL queries and statements.
  • Read-only queries (SELECT, SHOW, DESCRIBE) via the query tool.
  • Write operations (INSERT, UPDATE, DELETE) via separate tools.
  • Write tools are gated by the MYSQL_ALLOW_WRITE_OPS environment variable.
  • Communicates over standard input/output (stdio).

Use cases of MySQL MCP Server

  • AI assistants executing read-only reports or analytics on a MySQL database.
  • Automating data entry with INSERT statements through a chat interface.
  • Managing small-scale updates or deletions in a database via natural language.

Frequently asked questions

1

What does MySQL MCP Server do?

It acts as a bridge between MCP clients and a MySQL database, allowing AI assistants to run SQL queries and optionally modify data.

2

What are the dependencies for running MySQL MCP Server?

Node.js and npm are required to install and build the server. It also needs access to a running MySQL server and the corresponding connection credentials.

3

Where does the data reside?

All data stays in the user’s configured MySQL database. The server does not store or cache data externally.

4

What transport does MySQL MCP Server use?

It uses standard input/output (stdio) for communication with MCP clients.

5

How is authentication handled for MySQL?

Authentication is provided via the required environment variables `MYSQL_USER` and `MYSQL_PASSWORD`. Write operations can be further restricted by the optional `MYSQL_ALLOW_WRITE_OPS` variable, which defaults to `false`.
