dryrun

Overview

dryrun is a Model Context Protocol server that provides PostgreSQL schema intelligence from a committed snapshot without requiring any database connection or credentials. It exposes schema analysis and query validation as tools your AI assistant can invoke directly, making it safe to explore database structure and validate SQL migrations in your coding workflow.

The server runs entirely locally via the npm package @boringsql/dryrun, communicating over stdio with no setup beyond installation. No credentials are needed—it works immediately after you run npx -y @boringsql/dryrun. Version v0.15.1 is available under the BSD-2-Clause license, with full source code at boringSQL/dryrun on GitHub.

dryrun belongs in the Database category and integrates with MCP clients including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed, and others. If you maintain dryrun for boringSQL, claim this listing to verify ownership and keep information up to date.
