About Claudius

Claudius is a live leaderboard for the Claude plugin and MCP ecosystem. The ecosystem moves fast — new MCP servers, plugins, skills, subagents and hooks ship daily — and it's hard to tell what's genuinely good, actively maintained, and safe to install. Claudius tracks all of it in one ranked, filterable table.

Unlike MCP-only directories, Claudius covers every way to extend Claude Code and adds two signals nobody else surfaces: star velocity (7-day / 30-day growth) and a trust score that checks every packaged entry against the OSV.dev vulnerability database — which matters, given active supply-chain attacks targeting the AI tooling ecosystem.

The dataset updates daily through an automated pipeline: deterministic collectors refresh metrics from public APIs, and a Claude-powered curation pass classifies newly discovered candidates. Everything is open data in the repo.

Claudius is a community project, not affiliated with Anthropic. Listing is not an endorsement; review anything before installing it.
