The @bldbl/mcp package is the official MCP client/server component for Buildable that enables AI assistants (such as Claude and GPT) to operate directly with Buildable projects using the Model Context Protocol (MCP). It provides a type-safe, REST-based interface to fetch complete project context, access the project plan and tasks, determine the next best work item, start work, report progress, and mark tasks as complete. It also supports human collaboration by enabling discussions for questions and blockers. The package includes a Claude Desktop CLI integration, TypeScript support, and multiple installation options (Smithery for one-click Claude Desktop setup or manual npm/npx usage). You can configure separate MCP servers for multiple projects, each with its own API key and AI assistant identifier. Public API surface includes getProjectContext, getNextTask, startTask, updateProgress, completeTask, createDiscussion, healthCheck, and disconnect, along with error handling and a guided usage workflow for AI assistants.
