Overview

What is MariaDB MCP Server by CData?

A read-only MCP server that allows large language models (like Claude Desktop) to query live MariaDB data using natural language. It wraps the CData JDBC Driver for MariaDB and exposes it as SQL models accessible via simple MCP tools.

How to use MariaDB MCP Server by CData?

Clone the repository, build with mvn clean install, download and license the CData JDBC Driver for MariaDB, create a .prp file with your connection details (prefix, DriverPath, JdbcUrl, etc.), then configure your MCP client (e.g., Claude Desktop) to run the JAR with the .prp file as an argument. The server runs locally over stdio.

Key features of MariaDB MCP Server by CData

Exposes three MCP tools: get_tables, get_columns, run_query.
License under the MIT License.
Works with any MCP client that supports stdio transport.
Uses the CData JDBC Driver for robust connectivity.
No SQL knowledge required for end users.

Use cases of MariaDB MCP Server by CData

AI assistants answering business questions about MariaDB data.
Live analytics dashboards driven by LLM queries.
Ad-hoc data exploration without writing SQL.
Integration with Claude Desktop for conversational data access.

Frequently asked questions

Is this server read-only?

Yes, the project explicitly builds a local, read-only MCP server. The only query tool offered is `run_query` which executes SQL SELECT statements.

What are the dependencies?

You need Java, Maven, and the CData JDBC Driver for MariaDB (free trial or licensed). The JDBC driver must be installed and activated separately.

How do I configure the connection?

Create a `.prp` file with properties: Prefix, ServerName, ServerVersion, DriverPath (full path to the JDBC JAR), DriverClass (e.g., `cdata.jdbc.mariadb.MariaDBDriver`), JdbcUrl (connection string from the JDBC utility), and Tables (leave blank for all). Example content is provided in the README.

What transport does it use?

The server uses stdio transport, so it must run on the same machine as the MCP client (e.g., Claude Desktop). Remote access is not supported in this local build.

Does it support write, update, or delete operations?

No. Despite a mention of “read, write, update, and delete” in the usage section, the server is explicitly labeled as read-only and only provides a `run_query` tool for SELECT queries.
