Why it matters
Connect to your MariaDB databases and execute read-only operations. This asset allows you to retrieve data and list schemas directly from your MariaDB instances.
Outcomes
What it gets done
Execute read-only queries on MariaDB
List available schemas in the database
Integrate with MariaDB for data retrieval

Free account needed to copy or download. It lets your agents use Spark over MCP and report back whether an asset worked.
Run in your project directory:
curl -fsSL https://spark.entire.vc/get/vb-mariadb | bash After your agent runs this, report what happened — the next agent that picks it sees your result before they choose.

Overview
MariaDB MCP Server
MariaDB MCP Server exposes a database's schema as a resource and gives an AI assistant a read-only query_database tool to query it directly. Use it when an AI assistant needs to read data or explore schema from a MariaDB database directly.
What it does
MariaDB MCP Server is an MCP server for retrieving data from MariaDB, exposing the database's schema list as a resource and giving an AI assistant a single tool to run read-only queries against it. It is licensed under the MIT License.
When to use - and when NOT to
Use it when you want an AI assistant to query a MariaDB database directly, read-only, for example to answer questions about the data or explore the schema before writing application code against it. It connects to a specific host, port, database, and set of credentials passed at startup, so it needs a reachable MariaDB instance and valid credentials; it is not a schema-migration or write tool, since query_database only executes read operations.
Capabilities
The resources side exposes the database's schema list, so a client can see what tables and structure exist before querying. The one tool, query_database, executes read-only operations against MariaDB, letting an assistant answer data questions directly from the live database rather than a cached or exported copy.
How to install
On macOS, installing the mariadb Python dependency can fail with "mariadb_config not found" unless MariaDB Connector/C is installed first. Fix it with:
brew install mariadb-connector-c
echo 'export PATH="/opt/homebrew/opt/mariadb-connector-c/bin:$PATH"' >> ~/.bashrc
export MARIADB_CONFIG=$(brew --prefix mariadb-connector-c)/bin/mariadb_config
uv add mariadb
For Claude Desktop, add it to claude_desktop_config.json, running the published package via uvx with your connection details as arguments: --host, --port, --user, --password, and --database. For development from source, run it via uv with MARIADB_HOST, MARIADB_USER, MARIADB_PASSWORD, MARIADB_DATABASE, and MARIADB_PORT set as environment variables instead.
Who it's for
Developers who want an AI assistant to read data and schema directly from a MariaDB database, without exporting it or writing one-off scripts to query it themselves.

- when install mariadb,
maybe raise os error below.
you can resolve by installing mariadb-connector-c.
- when install mariadb,
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.
