Pick what it can do in Handwrytten
A preset of real Handwrytten operations. Each one becomes a tool the agent can call, and it can't touch anything outside the list.
Connect Handwrytten
One sign-in. The agent acts through your account, scoped to the operations you picked.
Add your personal MCP link
The last step mints a private MCP URL for this agent and walks you through exactly this, with your real link filled in. The page flips to Connected the moment your OpenCode first calls in. opencode mcp add only saves the config. OpenCode connects when it starts — run opencode, or restart a running one.
1. Run this in your terminal
2. Choose Remote and paste your server URL
3. Choose No when asked about OAuth authentication — the link itself is the key
<your-link> is your personal server URL — setup mints it for you.
