A curated directory of high-quality Claude Code extensions.
Cross AI Tools is a hand-picked directory of plugins, skills, and MCP servers for Claude Code. Unlike raw aggregators, we filter by quality — only extensions with proven adoption (500+ installs), active GitHub repos, and community trust make it here.
The directory is run by an editor: crawlers do the discovery, manual reviews keep the quality bar. We accept a small set of advertisers to fund that editorial work — all ads are clearly labeled.
Disclaimer: This is an independent, community-run directory and is not officially affiliated with Anthropic or Claude. Users should review plugin code and repositories before installation to ensure they meet their security and quality standards.
How we maintain quality
Every listing clears the same bar before it shows up here.
Step 01
Automated crawlers
Crawlers sweep skills.sh, GitHub, and the MCP registries on a schedule, refreshing installs, stars, and metadata across every listing.
Step 02
Quality thresholds
Skills need 500+ installs to be listed; stars and registry signals rank everything else. Abandoned and test entries never surface.
Step 03
Manual editorial review
An editor reviews new and borderline listings by hand, writes the summaries you see on detail pages, and curates the featured picks.
Step 04
Delisting sweeps
Recurring content-policy sweeps remove spam, adult, and off-topic listings so the catalog stays useful.
How discovery works
We crawl multiple sources to find extensions, then apply our quality filters:
- •Skills are crawled from skills.sh with install counts and filtered to 500+ installs
- •Plugin marketplaces are discovered from GitHub repositories with valid marketplace schemas
- •MCP servers are aggregated from community directories
- •GitHub star counts are refreshed regularly across all listings
