Early access — Generated from MCP tool sources; schemas evolve. Join the Product Brain Community.
Product Brain exposes a compact MCP tool surface. Most tools are compound tools with an action parameter so clients do not need to load many single-purpose tool definitions. Call orient first before substantive work.
