ImAiFox

ImAiFox is a free, open-source web directory that indexes and AI-grades Skills, Plugins, Agents, MCP Servers, and Prompts for Claude Code, Cursor, and Windsurf — all verified from GitHub and updated hourly.

What is ImAiFox?

ImAiFox is a web-based directory that aggregates AI "Boosters" — the site's term for Claude Skills, Plugins, Agents, MCP Servers, and Prompts — from GitHub. It takes GitHub repositories as input and produces standardized, quality-graded listings with health signals such as stars, maintenance status, and license. The platform runs entirely in the browser and includes a Stack Builder that recommends curated tool combinations. It was created by a developer who built a custom scraper to solve the fragmentation of AI-tool discovery, then used Claude to automatically grade every listing from A to F.

Key Features

• AI grading A–F — Every booster is graded by Claude on five criteria: documentation quality, functionality, maintainability, security, and originality, so you can compare quality at a glance.
• Hourly updates — An automated orchestrator scrapes GitHub and refreshes listings in real-time, so the directory never goes stale.
• 700+ MCP servers — The site indexes over 700 MCP servers from GitHub, sorted by popularity and maintenance status.
• Multi-type support — The first directory to index both Claude Plugins (executable code, hooks, MCP bundles) and Skills (SKILL.md prompt files) in one place.
• Compatibility filters — Each listing shows which platforms it supports (Claude Code, Claude Desktop, Cursor, Windsurf), and prompt templates work with ChatGPT and Gemini too.
• Stack Builder — Get a curated combination of Boosters matched to your workflow and tools.
• Health signals — Every entry includes GitHub stars, maintenance status, and license information.

Who is it for?

• Developers using Claude Code — Find and install Skills (SKILL.md files) to teach Claude Code specific tasks like code review or frontend design.
• Developers building AI agents — Discover Agents and Plugins that bundle commands, hooks, and MCP servers for deeper IDE integration.
• Teams evaluating MCP servers — Compare 700+ MCP servers side-by-side using the A–F grades and health signals to pick connectors for databases, APIs, and file systems.
• Prompt engineers — Browse prompt templates that work with any AI assistant, including ChatGPT and Gemini.

Use cases

• Automating code review — Install the "receiving-code-review" skill from the Superpowers collection to critically evaluate AI code review feedback before implementation.
• Auto-generating GitHub issues — Use the "gh-issues" skill to let an orchestrator fetch issues, spawn sub-agents to implement fixes, open PRs, and monitor reviews.
• Building front-end prototypes — Use the "d3-viz" skill for interactive data visualizations with D3.js, including validation and responsive design checks.
• Structuring feature development — The "feature-dev" skill walks through a 7-phase workflow with specialized agents for codebase exploration, architecture design, and quality review.

How does ImAiFox work?

ImAiFox automatically scrapes GitHub repositories for SKILL.md files, MCP servers, plugin packages, and agent definitions. An orchestrator extracts metadata, uses Claude to grade each entry on five criteria, and publishes the results to the site with health signals. Listings are updated hourly, and users can explore by category, sort by stars or newest, or use the Stack Builder for curated recommendations.

Pricing

ImAiFox is free to browse, and the Boosters listed are open-source projects hosted on GitHub.

FAQ

Is ImAiFox free?

Yes, ImAiFox is free to use. The site lists "Free" in its tags and the Boosters it indexes are open source.

What are Claude Skills and how do I install them?

Claude Skills are SKILL.md files that teach Claude Code to perform tasks. On each skill's page, you copy an AI-ready prompt and paste it into Claude Code. Skills are open source and hosted on GitHub.

What are MCP Servers and where can I find the best ones?

MCP (Model Context Protocol) Servers connect AI assistants to external services like databases and APIs. ImAiFox indexes 700+ MCP servers from GitHub, sorted by popularity and maintenance status.

What are Claude Plugins and how are they different from Skills?

Claude Plugins extend Claude Code with custom commands, hooks, and MCP servers as installable packages, whereas Skills are prompt-based SKILL.md files. ImAiFox is the first directory to index both.

Which AI assistants are compatible?

Most Boosters work with Claude Code, Claude Desktop, Cursor, and Windsurf. Prompt templates are compatible with any AI assistant including ChatGPT and Gemini.
