Many applications are just interfaces to databases, but traditional search filters often fail to capture complex user intent.
An LLM can be given a "tool" with a defined JSON schema, allowing it to translate natural language questions into SQL queries.
Allowing an LLM to execute raw SQL creates vulnerabilities for prompt injection to leak data and SQL injection to bypass read-only restrictions.
An MCP server acts as an intermediary that only executes whitelisted, parameterized queries, which drastically reduces the attack surface.
The MCP server enables safe write operations, like creating a reservation, by exposing specific tools instead of general SQL access.
Improve your MCP server's performance and reliability with caching, tool organization, specific outcome mapping, and clear error handling.
