What problem does it solve?
It removes the guesswork from building Model Context Protocol servers by helping you choose the right primitives, structure your API, and ship reliable server-side capabilities.
Core Features & Use Cases
- Tool design: Define focused executable actions with Zod schemas, validation, error handling, and structured responses.
- Resources and prompts: Expose read-only data, parameterized resources, and reusable prompt templates for richer AI workflows.
- Widget-based UX: Build interactive React widgets for visual experiences such as cards, dashboards, and searchable result lists.
- Server composition: Proxy and combine multiple MCP servers into one unified endpoint with namespaced tools and resources.
- Use case: Ideal for developers creating MCP apps that need production-ready patterns for weather apps, recipe finders, dashboards, and other tool-driven assistants.
Quick Start
Use the mcp-builder skill to design the MCP server you want, choose the tools or widgets needed for the workflow, and then implement it with the provided mcp-use patterns.
