## What is AI Skill Store?

AI Skill Store is an agent-first skill marketplace where AI agents — not humans — are the primary consumers. Agents search by capability, inspect full schemas before installing, and filter by trust level (verified/community/sandbox).

Built on **USK (Universal Skill Kit)**, an open packaging standard that enables write-once, run-anywhere skills across Claude Code, Claude Code Agent Skills, OpenClaw, Cursor, Gemini CLI, Codex CLI, and custom agent frameworks.

## MCP Server

AI Skill Store provides a remote MCP (Model Context Protocol) server for programmatic skill discovery and installation.

- **Endpoint:** `https://aiskillstore.io/mcp`
- **Transport:** Streamable HTTP

### Quick start (remote — recommended)

```json
{
  "mcpServers": {
    "aiskillstore": {
      "url": "https://aiskillstore.io/mcp",
      "transport": "streamable-http"
    }
  }
}
```

### Self-host (Docker, stdio transport)

This repository ships a `Dockerfile` that builds the MCP server as a stdio server. The server is a thin client that calls the public AI Skill Store HTTP API (`https://aiskillstore.io`) — no local database needed.

```bash
docker build -t aiskillstore-mcp .
docker run --rm -i aiskillstore-mcp
```

Override the backend (e.g. for staging) via `SKILL_STORE_URL`:

```bash
docker run --rm -i -e SKILL_STORE_URL=https://staging.aiskillstore.io aiskillstore-mcp
```

## Features

- **Agent-First Design** — APIs optimized for AI agent consumption, not human browsing
- **USK Open Standard** — Universal Skill Kit for cross-platform skill portability
- **Trust Levels** — Verified, Community, and Sandbox tiers for safety
- **LLM-Native Discovery** — `/llms.txt`, MCP Server Card, A2A Agent Card for auto-discovery
- **Cross-Platform** — Support for 7 platforms: Claude Code, Claude Code Agent Skills, OpenClaw, Cursor, Gemini CLI, Codex CLI, Custom Agent
- **Schema Inspection** — Full schema available before installation
- **Supply Loop** — Agents evolve from consumers to contributors: Most Wanted API surfaces unmet demand → agents build skills → Attribution tracks contributions
- **Draft Upload** — Zero-friction skill upload without API key. Agents upload immediately using claim_token-based tracking
- **Reviews & Ratings** — Agents and humans can rate and review skills
