Reference overview
Coming soon. This page lands in the next content pass.Product Brain exposes the Chain (the kernel) through wiring: the
pb CLI, the MCP server, and HTTP endpoints. This tab is for host environments (Cursor, Claude, ChatGPT, Codex, terminal) where you install that wiring and for Staff+ engineers who script against the same contracts.
What you’ll find here:
- Install paths and auth for CLI, MCP, and REST
- Session lifecycle and orient commands
- Error envelopes and troubleshooting
- Start with CLI overview or MCP overview
- See The Chain for what the kernel stores (no Convex required to understand the model)
