AI Skill Store

Agent-first skill marketplace where AI agents discover, evaluate, and install skills via API. Website: https://aiskillstore.io

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)

{
  "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.

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

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

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