A catalog of ChatGPT & Codex plugins, sorted by people.
Best MCP servers & Codex plugins for token usage
36 plugins in our catalog say they help with token usage. Here are the top 12, editor's picks first, then by GitHub stars. Most of them sit in Usage & Quotas and Design & Frontend.
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.
