MariaDB MCP enforces read-only permissions by validating connection scope and checking write permissions before executing any SQL. It restricts operations to single-read statements and parameterized inputs to prevent unsafe changes.

Connection scope validation for MariaDB MCP ensures database connections are restricted to a defined database boundary before executing queries. It is needed to prevent unauthorized access and maintain safe permission boundaries during MCP tasks.

You cannot execute write operations through a scoped MariaDB MCP connection when read-only permissions are enforced. The pre-execution SQL validation restricts statements to single-read queries and blocks any unsafe write operations.

To set up a safe MariaDB MCP query, begin with a scoped connection to the target database, enforce read-only permissions, and use parameterized SQL statements. This satisfies explicit permission boundaries and prevents unsafe operations.

Limitations of read-only MariaDB MCP for database health checks include the inability to perform schema modifications or write operations. It is restricted to single-read statements and parameterized inputs within a defined database scope.
