MySQL-MCP-Server: Connecting AI Applications to MySQL Databases via Model Context Protocol (MCP)

Overview: What is MySQL-MCP-Server?

MySQL-MCP-Server is an MCP server designed to connect AI applications, specifically those integrated with the Model Context Protocol (MCP), to a MySQL database. By exposing the database's table structure as a resource and allowing only read-only SQL queries, this server enables advanced AI applications like Claude Desktop, Continue, and Cursor to interact with structured data from any MySQL database in a controlled manner.

🔧 Core Features & MCP Capabilities

MySQL-MCP-Server offers several key capabilities that leverage the Model Context Protocol (MCP):

1. Database Access: The server acts as an intermediary between AI applications and a MySQL database, ensuring secure and efficient access to table structures.
2. SQL Query Tools: Users can run SQL queries on the database through MCP-compliant interfaces provided by AI clients.
3. Data Analysis Tips: Predefined hints for common data analysis tasks are included, facilitating more effective use of the server's capabilities.

⚙️ MCP Architecture & Protocol Implementation

The architecture of MySQL-MCP-Server is built to be compatible with the Model Context Protocol (MCP). The protocol ensures seamless integration between AI applications and the server. Below is a diagram illustrating the protocol flow:
