What is an MCP gateway?
▸ TL;DR
An MCP gateway is one server that proxies many. Unyly Gateway (gateway.unyly.org/mcp, OAuth 2.1) exposes the whole 80,000+ catalog to any client through three meta-tools: search, inspect, call — one connection instead of dozens of installs.

Instead of installing servers one by one, the agent connects to a single gateway endpoint and gets meta-tools: search_mcps finds a server by task, list_mcp_tools inspects it, use_mcp_tool calls it. The gateway handles auth (OAuth 2.1 with dynamic client registration), routing, metering and per-team token control. Teams can pin private servers next to the public catalog. It works today in Claude (web and desktop), ChatGPT, Cursor, VS Code and Windsurf; setup is pasting one URL.

What is MCP hosting and can I run servers without installing them?
MCP hosting runs the server on remote infrastructure instead of your machine. On Unyly you connect hosted servers by URL with OAuth: nothing to install, no Node or Python, works from Claude, ChatGPT and Cursor.
Is there an App Store for Claude MCP servers?
Yes — Unyly works like an App Store for Claude: browse 80,000+ MCP servers, read security scans, and install in one click into Claude Desktop, Claude Code, Cursor or ChatGPT. No JSON, no terminal.
