Directories
The catalogues worth knowing in the Claude ecosystem. Each row says what it covers, roughly how big it is, when we last opened it — and our own view on when to reach for it rather than one of the others.

Anthropic's own public repository of Agent Skills, including the document skills shipped with Claude.
Use this when you want the vendor's own skills before reaching for the community's. Start here to see what the format is meant to look like, then go to the community catalogues for coverage.
Anthropic's own task-oriented prompt examples with system and user messages.
Use this when you want examples that are known to work rather than theory. Useful as a pattern reference; it is not exhaustive and is not meant to be.
- awesome-claude-pluginsSkills and plugin cataloguesOver 15,000 indexed plugin repositories as of May 2026 (approximate)checked August 16, 2026
A GitHub-indexed listing of Claude plugin repositories, assembled by crawling rather than by curation.
Use this when you need to know whether something exists at all. Indexed from GitHub, so inclusion says nothing about quality — a repository with two stars and one with forty thousand sit side by side.
Indexed MCP servers with per-server security, licence and quality scoring, plus a hosted gateway.
Use this when you want the widest possible net and are willing to filter yourself. Breadth is the point here; maintenance status and security posture are not surfaced, so treat every result as unvetted until you check the repository.
- Anthropic CookbookPrompt librariesLarge notebook collection maintained by Anthropicchecked August 16, 2026
Runnable notebooks showing prompting patterns, tool use, RAG and evaluation.
Use this when you are building rather than prompting. Working code for API patterns, closer to a developer reference than a prompt collection — go here when the question is how to implement something, not how to phrase it.
CLI and web catalogue of Claude Code agents, commands, hooks, MCP configs and settings.
Use this when you are setting up a project and want a working starting point rather than documentation. Templates get you running quickly, so read what they configure before you adopt them wholesale.
- mcp.soMCP directoriesTens of thousands of listings; no official count publishedchecked August 16, 2026
Broad open catalogue of MCP servers and clients, searchable by tag and use case.
Use this when you are browsing rather than hunting — the categorisation is easier to skim than a raw index, which makes it a better starting point if you do not yet know what you are looking for.
Hand-picked list of Claude Code commands, CLAUDE.md files, hooks and workflows.
Use this when you want the Claude Code corner of the ecosystem specifically. Narrower than the general plugin indexes, which is the point — less to filter through if Claude Code is what you are working in.
- Prompt Engineering GuidePrompt librariesDozens of techniques, continuously updatedchecked August 16, 2026
Model-agnostic reference of prompting techniques with papers and worked examples.
Use this when you want the reasoning behind the technique rather than a snippet to copy. Broader than Claude, which makes it useful for transferring what you know between models.
Curated MCP server and client listings with a weekly newsletter and use-case write-ups.
Use this when you want to keep up rather than look something up. It is closer to curated than exhaustive, and the newsletter is the part most people actually come back for.
Registry plus hosting and one-command install of MCP servers into clients.
Use this when you want to run a server without hosting it yourself. The index is the smallest of the four majors, but it is the one that gets you from browsing to running in the fewest steps.
- Model Context Protocol reference serversMCP directoriesAbout 90,000 GitHub starschecked August 16, 2026
The protocol maintainers' own reference and community server list.
Use this when you want the reference implementations rather than the community's. These are the servers the protocol authors maintain, which makes them the right place to learn how an MCP server is supposed to be built — and the wrong place to look for the long tail.
Community-maintained index of MCP servers grouped by category.
Use this when you want a human-curated list instead of an index. Someone decided what goes in, which is exactly the filter the large directories lack — and exactly the bottleneck when a list falls behind.
How this list is kept
- No bare lists. An entry is only published once we can say when it is the right one to open. Without that, it stays a draft.
- Checked, not collected. Every URL is opened and verified; the date you see is the day we last did it.
- Sizes are approximate. Where a catalogue publishes a count we quote it; where it does not, we say so rather than guess.
- Independent. No placements are paid, and outbound links carry no affiliate tracking.
