Step-by-step setup

1. Install the plugin

   In Claude Code, run:

   claude plugin marketplace add seedlinglabs/forgebench-plugin
   claude plugin install forgebench@forgebench

   Then ask your Claude Code agent to run /reload-plugins so the newly installed plugin is available in the current session.

2. Sign in with OAuth

   1. Run /mcp in Claude Code (or open Cursor's MCP Settings).
   2. Select forgebench and click Authenticate.
   3. Sign in on the browser page that opens, select your workspace, and approve access.

3. Verify connection

   Type in chat:

   "Who am I in Forgebench?"

   Your assistant will print your active workspace, your role, and the default agent policies.
