Install Arcade in any MCP client

Any client that speaks the Streamable HTTP MCP transport can use Arcade tools, OpenCode included. Add this as an MCP server:

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

Your agent gets every tool on the gateway. Nothing else about how you use it changes.

One-click links

Cursor and VS Code can add the gateway without editing any config:

• Cursor: use this link  for a one-click MCP install.
• VS Code: use this link  for a one-click MCP install.

Both of those clients also load the full plugin, so use these only if you want the tools on their own. Install the agent plugin for the rest.

Sign in

Your client signs you in to Arcade when it first connects, and each app gets authorized the first time a task needs it. See signing in for how the two layers fit together.

Try it

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

Next steps

• Tools-only MCP server: what you give up by skipping the plugin
• 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
