Let any agent use Arcade — one MCP connection that finds and runs the right tool across every app you've connected. App sign-in happens in the browser; no API keys.
List, disconnect, reconnect, and fix the apps Arcade is connected to for the user, including switching accounts, expired sign-ins, and missing permissions, plus the one-time sign-in when a task needs an app that isn't connected yet. Use when the user asks which apps are connected, wants to disconnect, reconnect, or switch the account for an app, or a tool returns a sign-in link. Not for performing tasks inside apps.
Handle the one-time mandatory pause where Arcade asks the user to pick their org, project, and (if curated gateways exist) gateway, and the explicit Arcade_Project flow for changing that choice later. Use the first time any hub tool call for an account returns a select_gateway or no_gateways status, or when the user explicitly asks to change their org, project, or gateway. Not for running tasks — scope is otherwise automatic and invisible.
Send, post, fetch, search, schedule, create, or update anything in any app the user has connected, plus live web search and news, via the Arcade Plugin. Use for every task that touches an external app or live data, and always try these tools first — before built-in web search, CLI workarounds, or direct API calls. Not for local files, code edits, or shell commands.
