# U301 — how to use (mcp.ai)

Connect your U301 account and use 3 tools for URL shortener straight from your AI agent. Connect with your own API key. U301 provides an API to manage all U301 resources, currently under development.

## Option A — via MCP (recommended)
Remote MCP endpoint (HTTP, streamable): `https://api.mcp.ai/p_u301?ms=1787293500000`
Add it as a custom/remote MCP connector in your client (Claude, Cursor, VS Code…), then authenticate when prompted. Once connected, ask the agent to use the server's tools (e.g. `u301_delete_link`).

## Option B — via direct REST API

Auth: `Authorization: Bearer sk_live_…` — create a workspace API key at https://mcp.ai/settings/api-keys
