Quarry

Overview

Quarry is a Model Context Protocol server that provides safety-railed database access for agents working with Postgres, MySQL, and Redis. It operates read-only by default, allowing MCP-compatible AI assistants to query databases directly while maintaining security constraints. The model determines when and how to use Quarry's tools during conversations or agent runs.

Quarry runs locally via the uvx quarry-db package, communicating over stdio with no authentication required. It works immediately out of the box. The latest release is v0.2.2, distributed under the MIT license with source code available at Wangggym/quarry on GitHub.

Quarry is categorized as a Database tool on mcp.site and integrates with MCP clients including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed, and others. If you maintain Quarry for Wangggym, claim this listing to verify ownership and keep the information current.
