About marketplace

marketplace is a scored directory of AI-agent building blocks: MCP servers, Claude skills, and other agent extensions published as open-source repositories.

What we track

Entries are discovered through GitHub's topic index — the mcp-server, claude-skill, and ai-agent topics — and grouped by the topic they were found under. For every entry we record community adoption (GitHub stars), maintenance activity (last push), issue pressure (open issues relative to stars), language, and license.

How the score works

The composite score (0–100) blends popularity, maintenance recency, and issue pressure, so actively maintained and widely adopted skills and servers surface first. Data is refreshed every six hours.
