Install Arcade in any MCP client

Any client that can talk to a Streamable HTTP MCP server can use Arcade tools, including OpenCode and clients that do not support agent plugins at all. Add this URL as an MCP server:

https://api.bosslevel.dev/mcp/all-optimized

That gives you tools only. The plugin’s skills, commands, and arcade-operator subagent need a client that loads agent plugins . See the install guide for the list.

Sign in to your apps

No API keys. The first task that touches an app returns a browser sign-in link. Approve it once and Arcade holds the token from then on.

Try it

• “What’s on my calendar tomorrow?”
• “What apps can Arcade use?”

Next steps

• Install the agent plugin: one command for Cursor, Claude Code, VS Code, Copilot CLI, and Codex
• Connect to MCP clients: point a client at a gateway you control, with your own tool list
• From trial to team rollout: what changes when a team depends on the workflow
