Find the right skill, MCP server or plugin in seconds

A directory for the AI tooling ecosystem: agents, skills, MCP servers, workflows, prompts and tools, searchable, filterable, and installable with one command.

Two reasons. In DNS, an AAAA record is what points a name to an address — which is exactly what we do: you give us a name, we point you to the right agent, skill or MCP server. Also, your fingers are already resting on the A key. We checked.

Reusable instruction sets (SKILL.md files) that teach an AI coding agent a specific task. Install one with a single command and your agent picks up the capability.

Servers built on the Model Context Protocol that extend an agent with tools, APIs and integrations, browsers, databases, GitHub, and more.

Bundles of skills, subagents, hooks and MCP servers shipped as one installable package for coding agents like Claude Code. Install a plugin and you get everything inside it in one step.

Specialized assistants for coding agents — each a single markdown file with its own prompt, tool access and context window. Drop one in and delegate focused tasks to it.

Open any listing and copy the install command, Project, Global, or Try-once scope. Most install with one command.

Browse the skills directory, open the one you want, and run its install command. Once installed, your agent loads the SKILL.md automatically and applies it whenever the task comes up — no extra prompting needed. Start with the most-installed picks in Best Claude Skills.

Find a skill or plugin here, copy its one-line install command, and run it in your project or globally. Claude Code picks up the new skill on the next session. Plugins bundle several skills, subagents and MCP servers so you can add a whole toolkit in one step.

SKILL.md is the plain-markdown file that defines an agent skill: a short description of when to use it plus the instructions the agent should follow. It's the format Claude Code and other skills-compatible agents read, and it's what every skill in this directory ships.

That's what this directory is for. Every taxonomy has a ranked 'best of' page built from live install counts and GitHub stars — Best Claude Skills, Best MCP Servers, Best Claude Code Plugins and more — so you're always seeing what's actually being used, not a stale awesome-list.

Rankings come from install counts, GitHub stars and freshness. Verified badges mark official publishers. Dead or abandoned tools drop out of the index.

No. aaaa.fyi is an independent, vendor-neutral directory. We index tools from across the ecosystem and rank them by public data — install counts and GitHub activity — not partnerships. We're not affiliated with or endorsed by Anthropic or any vendor.
