MCP Server Dev

The core build-mcp-server skill follows a structured five-phase workflow: it interrogates your use case, recommends a deployment model (remote HTTP, elicitation, MCP app, MCPB, or local stdio), selects a tool-design pattern (one-tool-per-action vs. search+execute for large APIs), picks a framework (TypeScript SDK or FastMCP for Python), and scaffolds your project. The build-mcp-app skill adds interactive UI capabilities — form widgets, searchable pickers, confirmation dialogs, charts, and live-updating status displays — rendered directly in chat via sandboxed iframes. The build-mcpb skill handles packaging local stdio servers with their runtime into installable bundles that require no Node.js or Python on the user's machine.
