AppSkill

AppSkill is an AI skill platform that lets you build, host, and run custom tools in plain English, then connect them to any MCP-compatible LLM environment in one click. You describe what you want a skill to do, AppSkill generates the code, hosts it, and exposes it as a native MCP tool. Once connected, your LLM can call your skills exactly like any built-in tool, no setup required on every session. What you can do with this connection: Run your own skills across all your AppSkill projects as native tools in Claude, Cursor, Windsurf, and VS Code Access marketplace skills built by other creators without leaving your coding environment One OAuth connection covers every project you own, automatically How it works: Connect once using OAuth. AppSkill issues a token scoped to your account. Every skill you have marked active appears immediately as a callable tool, namespaced by project so you always know which workspace a tool belongs to. Skills execute in isolated E2B sandboxes, so nothing runs on your machine. Built for: Vibe coders and AI-first builders who want to extend their LLM environment with custom logic without writing infrastructure, managing deployments, or copying API keys between tools.
