MCP Server Dev

mcp-server-dev

Skills for designing and building MCP servers that work seamlessly with Claude.

What's inside

Three skills that compose into a full build path:

Skill	Purpose
build-mcp-server	Entry point. Interrogates the use case, picks deployment model (remote HTTP / MCPB / local stdio), picks tool-design pattern, routes to a specialized skill.
build-mcp-app	Adds interactive UI widgets (forms, pickers, confirm dialogs) rendered inline in chat. Works on remote servers and MCPB bundles.
build-mcpb	Packages a local stdio server with its runtime so users can install it without Node/Python. For servers that must touch the local machine.

How it works

build-mcp-server is the front door. It asks what you're connecting to, who'll use it, how big the action surface is, and whether you need in-chat UI. From those answers it recommends one of four paths:

• Remote streamable-HTTP (the default recommendation for anything wrapping a cloud API) — scaffolded inline
• MCP app — hands off to build-mcp-app
• MCPB — hands off to build-mcpb
• Local stdio prototype — scaffolded inline with an MCPB upgrade note

Each skill ships reference files for the parts that don't fit in the main instructions: auth flows (DCR/CIMD), tool-description writing, widget templates, manifest schemas, security hardening.

Usage

Ask Claude to "help me build an MCP server" and the entry skill will trigger. Or invoke directly:
