MCP Server (AI Agent Integration)

Sequel Ace includes a built-in Model Context Protocol (MCP) server that lets AI agents (Claude Code, Cursor, and others) query your databases through Sequel Ace's existing connections. It is off by default, listens on localhost only, and runs in read-only mode unless you turn that off.

Enable it under Preferences > MCP Server. See the MCP server guide for setup, the full tool list, client configuration, and the security model.

Tags & Releases

• production/ tags represent submissions to the macOS App Store. These are marked as "Pre-Release" until approved by Apple and officially released by the team. Both release candidates and final releases use production/ tags. Release candidates will have RC or Release Candidate in their title.
• beta/ tags represent pre-release versions of Sequel Ace intended to test new features and bug fixes. The downloadable app in a beta/ tag has a different name and identifier (Sequel Ace Beta), meaning you can install it side-by-side with the latest App Store release. Beta releases also have increased logging turned on to help us identify critical issues.
