SQL Database Connector FAQs

Question 1

How does the connector ensure safety when LLMs query databases?

Accepted Answer

Safety features include read-only access by default, automatic row limits (default 100), query timeouts (default 30s), and credential redaction. For PostgreSQL/MySQL, it also uses `SET TRANSACTION READ ONLY`.

Question 2

What tools are available for LLMs to manage and query databases?

Accepted Answer

LLMs can utilize structured tools for database introspection (e.g., `list_databases`, `list_tables`, `describe_table`, `sample_data`) and to execute arbitrary SQL queries via the `query` tool, returning results as JSON.

Question 3

Can LLMs perform write operations (INSERT, UPDATE, DELETE) using this tool?

Accepted Answer

By default, the connector enforces read-only access. Write operations are disabled but can be explicitly enabled by setting the `--allow-write` flag during configuration.

Question 4

What is the SQL Database Connector (mcp-sql)?

Accepted Answer

The SQL Database Connector (mcp-sql) enables Large Language Models (LLMs) to securely connect and interact with PostgreSQL, SQLite, and MySQL databases, facilitating data retrieval and management tasks.

Question 5

Which databases does the SQL Database Connector support?

Accepted Answer

It provides full support for PostgreSQL, SQLite, and MySQL databases. Connections can be established using standard URLs or environment variables.
