FAQ from Databasemcpserver

What databases are supported by Databasemcpserver?

Databasemcpserver supports 34 database types, including MySQL, SQL Server, SQLite, PostgreSQL, Oracle, domestic databases (e.g., Dameng, Kingbase, Oscar, HGDB), distributed databases (e.g., OceanBase, TiDB, PolarDB, Doris), and time-series databases (e.g., TDengine, QuestDB, ClickHouse).

How does Databasemcpserver protect against dangerous operations?

The server automatically detects and blocks high-risk SQL like DROP TABLE, TRUNCATE TABLE, ALTER TABLE, and DELETE/UPDATE without WHERE conditions. To perform such operations, specialised schema tools (e.g., drop_table, truncate_table) must be used, which provide explicit risk prompts.

How do I install Databasemcpserver?

The recommended method is as a .NET Global Tool: dotnet tool install --global DatabaseMcpServer. Alternatively, install via dnx [email protected] --yes or clone the repository and run dotnet run from the source directory.

Do I need to specify the database type every time?

No. The database type is set once via the DB_TYPE environment variable (default MySql). Similarly, the connection string is set via DB_CONNECTION_STRING. These environment variables are read from the MCP client configuration.

Can I execute stored procedures with Databasemcpserver?

Yes. Databasemcpserver provides call_stored_procedure for simple calls and call_stored_procedure_with_output for procedures with output parameters, both accessible through natural language prompts.
