Connect your agent
a123d is designed with an AI agent: you describe and mark up parts, the agent builds and checks them in your workspace through MCP. Add this server to your agent:
Claude Code — run:
then type /mcp in Claude Code and choose a123d → Authenticate. A browser tab opens
here; approve with your passkey and the agent appears under Agents with access below.
Other MCP clients (Claude desktop / web custom connector, Cursor, …): add a remote MCP server with the URL above. They sign in through the same approval page.
Start with the guide tool; get_markings shows what you marked
in the studio, and wait_for_markings waits for new ones.
Optional: a local channel pushes each marking you save straight into a Claude Code session. It needs a personal token:
Copy it now — it won't be shown again. Revoke it under Agents with access, like an agent.
With the a123d repo checked out, add to .mcp.json:
and start Claude Code with
claude --dangerously-load-development-channels server:a123d-markings.
