Agent Skills Marketplace
SkillsMP · Coding · Productivity
Agent Skills Marketplace is a free web platform that indexes more than 3 million open-source agent skills pulled from public GitHub repositories. It lets you search, filter, and compare Claude skills and Codex skills, then jump back to the original repo before you install anything. No signup wall, and no paid tier. A REST API and an MCP server are open for anyone building their own tools on top of it.
About Agent Skills Marketplace
What Is Agent Skills Marketplace
Agent Skills Marketplace (also written as SkillsMP) is a discovery layer for the fast-growing pile of SKILL.md files that people publish on GitHub. Instead of scrolling through repositories one by one, you get keyword search, occupation categories, and source context in a single place.
It solves a simple but annoying problem: there are millions of agent skills now, and nobody can tell which ones are worth a look. The site gathers them, groups them by field and job title, and pushes you back to the real project page so you can read the code yourself. The project's own stance is that it doesn't judge skill quality yet. It organizes, then gets out of the way. That restraint is refreshing.
The main limit is trust. Skills are scraped from public repos and the site isn't affiliated with Anthropic or OpenAI, so nothing here is vetted. You still have to review a skill before installing it, and the site says so plainly. Coverage also depends on what's public. Private or invite-only skills won't show up at all.
Getting Started
- Open skillsmp.com and type a keyword or skill name into the search box, or browse the category and occupation lists.
- Narrow the results with filters. Content language, category, and occupation all help cut the noise.
- Open a skill's detail page and check the source repository, the creator, and where the file actually lives.
- Read the SKILL.md. Listings aren't verified, so the repo is the only thing you can really judge.
- For programmatic use, grab a free API key from the developer portal or connect through the MCP server.

Best for
The users, tasks, and scenarios where this tool fits best.
Users
- AI developers hunting for reusable Claude Code or Codex skills without trawling GitHub by hand
- Automation builders who want to wire skill lookup into their own tools through the API
- Curious beginners who want to see what kinds of tasks people are turning into skills
Tasks
- Searching for a skill by keyword, name, or job title and comparing whether the source looks trustworthy
- Filtering skills by content language when you only want English or Japanese listings
- Pulling skill metadata into a script or agent through the free REST API
- Mapping which skills show up in a given field before you commit to building one yourself
Scenarios
- You've heard about agent skills but have no idea what already exists, so you start from the occupation view
- You're assembling a coding agent workflow and need a batch of related skills fast
- You want to check whether a popular skill is genuinely from a real repo and not a repost
Key features
Search Across 3M+ Skills
The core of the site is search, and it's the main answer to AI skill discovery. It pulls SKILL.md files from public GitHub repositories and builds a keyword index over names, repositories, and descriptions. So how do you find anything useful among 3 million files? Filters, mostly. Matching was tightened to handle names with hyphens, underscores, or dots, which matters because plenty of skills use those patterns. You can combine a keyword with category and occupation filters to shrink a huge result set into something browsable.
Occupation and Category Browsing
Beyond raw search, SkillsMP organizes skills by occupation using the U.S. Department of Labor SOC taxonomy, covering more than 800 job titles. There are also 12 domains and 50+ categories. This framing is useful when you don't know the exact skill name you want. Start from "data analyst" or "designer" and see what people in that line of work are actually building. No guessing required.
Free REST API
Developers get a REST API with an auto-generated OpenAPI spec. Anonymous access allows 50 requests a day, and a free API key lifts that to 500. That's enough for a personal script or a small internal tool that looks up skills on demand and caches the results locally. The API is the project's answer to a real problem. With this many skills, discovery itself needs tooling, not just a webpage.
MCP Server for Agents
There's a Model Context Protocol endpoint so an AI agent can query the skill catalog directly during a task. MCP access needs no API key and carries no daily quota, but per-IP short-window rate limits still apply. It's the most interesting piece for anyone building agent-to-agent workflows.
Source Context and Repo Links
Every listing points back to the creator, the repository, and the original file location, which means you can trace exactly where a skill came from before you install or reuse it. The site's stated goal is to send you to the real source. That's a meaningful design choice, because it treats the catalog as a map rather than a store.
Multilingual Browsing
The interface and filtering support 9 languages, and there's a content-language filter so you can isolate skills written in a specific language, which is handy when English results keep crowding out everything else. Non-English pages render occupation names in the current language too, which makes the occupation view usable outside English.
Pros and cons
Pros
- Completely free with no paid tier, and all indexed skills are open source
- Indexes 3M+ skills, so obscure or newly published ones are more likely to surface
- Free REST API and an MCP server give you real programmatic access, not just a website
- Occupation and category browsing helps you explore without knowing exact skill names
- Every result links to the source repo so you can verify before installing
Cons
- Nothing is vetted or quality-ranked, so a listing tells you a skill exists, not that it's good
- Only public GitHub skills appear, so private or internal skills are invisible
- Anonymous API access is capped at 50 requests a day, which runs out quickly for heavier use
Frequently asked questions
Yes. The site is completely free, with no paid tiers at all. Anonymous API access allows 50 requests a day, and a free API key raises that to 500. The MCP server doesn't need a key.

Agent Skills Marketplace Alternatives
Forefront
Forefront · CodingForefront is a web platform for building with open-source AI. It lets you fine-tune leading open-source language models on your own data, evaluate how they perform, and run them through an API or export them to host yourself. Developers who want the convenience of a closed-source platform but insist on owning their models and data are the target audience here.
Startkit
StartKit.AI · CodingStartkit is a boilerplate for building AI SaaS and AI wrapper products. Think of it as an AI startup boilerplate with the boring parts already wired up: authentication, Stripe and Lemon Squeezy payments, usage limits, transactional email, and an AI API starter that talks to OpenAI, Anthropic, Groq, or Llama. You clone the repo, set your price, and start on the part of your product that people actually pay for. It's Next.js under React and Tailwind, so most of the boilerplate code already feels familiar.
Testim
Tricentis · CodingTestim is an AI-powered test automation platform for building and running end-to-end tests across web, mobile, and Salesforce applications. It leans on machine learning to keep tests stable when an interface changes, so teams spend less time fixing broken selectors. Not bad for an automated testing tool you can start using today. You create tests by recording actions in a browser, then optionally add JavaScript when you need more control. It's a solid pick for busy QA teams.
