Frequently Asked Questions
What is an MCP server for Postgres?
An MCP (Model Context Protocol) server for Postgres lets AI agents like Claude, Cursor, and Windsurf query PostgreSQL databases directly. The agent sends natural language or structured queries, and the MCP server translates them into SQL and returns results.
Which MCP server for Postgres is best for read-only access?
For read-only access, look for MCP servers that enforce query-only mode by default. This prevents accidental writes and is safer for production databases.
