About mcp-server-mariadb
mcp-server-mariadb is an MCP server that provides read-only access to MariaDB databases. It is aimed at users who want AI assistants to inspect database schemas and query data without write access.
Key features
- 01Schema list exposed as MCP resources
- 02query_database tool for read-only queries
- 03Run with uv or uvx, with published and development configurations
Use cases
- 01Letting an AI assistant inspect MariaDB table structures
- 02Querying business data from Claude Desktop in read-only mode
- 03Testing local changes to the server during development
MCP support
This is an MCP server that exposes the database schema list as a resource and provides a query_database tool for read-only queries to MCP clients.
Configuration
Local server config is the same for every client. Copy it into your client’s MCP config file.
We haven’t collected a package or remote endpoint for this server. Follow the instructions in the project README.
Tools
Local servers expose tools only once running on your machine, and the maintainer has not provided a tool list.

dependency
install mariadb
- mac
- when install mariadb, maybe raise os error below. you can resolve by installing mariadb-connector-c.
OSError: mariadb_config not found.
This error typically indicates that MariaDB Connector/C, a dependency which
must be preinstalled, is not found.
If MariaDB Connector/C is not installed, see installation instructions
If MariaDB Connector/C is installed, either set the environment variable
MARIADB_CONFIG or edit the configuration file 'site.cfg' to set the
'mariadb_config' option to the file location of the mariadb_config utility.
- execute
brew install mariadb-connector-c - execute
echo 'export PATH="/opt/homebrew/opt/mariadb-connector-c/bin:$PATH"' >> ~/.bashrc - set environment variable
export MARIADB_CONFIG=$(brew --prefix mariadb-connector-c)/bin/mariadb_config - execute
uv add mariadbagain.
Usage with Claude Desktop

New to MCP?
From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
