    Create a Secure PostgreSQL MCP Server with n8n

    Set up a PostgreSQL MCP server using n8n to manage database operations securely, supporting select, insert, and update queries.

    This workflow demonstrates how to construct a PostgreSQL MCP server using n8n, enabling secure management of your PostgreSQL database. It integrates with MCP clients to perform read, insert, and update operations while ensuring security by restricting raw SQL queries. The workflow leverages n8n's PostgreSQL and custom workflow nodes to handle database interactions, ensuring that only parameterized queries are executed to mitigate SQL injection risks.
