A catalog of ChatGPT & Codex plugins, sorted by people.
Best MCP servers & Codex plugins for database
7 plugins in our catalog say they help with database. Here are the top 7, editor's picks first, then by GitHub stars. Most of them sit in Data & Backend and Memory & Context.
How to choose
- Match the host first: Codex and Claude Code install commands differ, and the install line below shows which one each project targets.
- Check where it runs. Hosted MCP endpoints are quicker to set up but send your requests to someone else's server.
- Prefer a recent push and a real license (MIT or Apache-2.0) for anything you'll use at work.
- Stars tell you how many people looked, not whether it works. Read the code before you install.
The list
1. LLMSlim
