mcp-builder
DEPRECATED: This skill has been replaced by `mcp-app-builder`. Check if `mcp-app-builder` is available in the skills folder. If not, install it: `npx skills install mcp-use/mcp-use --skill mcp-app-builder` Use `mcp-app-builder` instead of this skill. Build Model Context Protocol (MCP) servers with mcp-use framework. Use when creating MCP servers, defining tools/resources/prompts, working with mcp-use, bootstrapping MCP projects, or when user mentions MCP development, tools, resources, or prompts.
Why this skill is useful
Provides specific commands and patterns for building MCP servers that the AI wouldn't reliably generate on its own.

What this skill does
MCP Server Builder Build production-ready MCP servers with tools, resources, prompts, and interactive widgets using mcp-use. Before You Code Decompose user requests into tools, widgets, and resources. Decide what needs UI vs text. Read design-and-architecture.md: when planning what to build, deciding tool vs widget, or designing UX flows. Implementation Tools, resources, prompts → tools-and-resources.md: when writing server-side server.tool(), server.resource(), server.prompt() code Visual widgets (React TSX) → widgets.md: when creating interactive UI widgets in resources/ folder Response helper API → response-helpers.md: when choosing how to format tool/resource return values URI template patterns → resource-templates.md: when defining parameterized resources Quick Reference Response helpers: text(), object(), markdown(), html(), image(), audio(), binary(), error(), mix(), widget() Server methods: server.tool(), server.resource(), server.resourceTemplate(), server.prompt(), server.listen()
