About

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:

/mcp-server-dev:build-mcp-server

Questions

What does the mcp-server-dev plugin do?

How do I install mcp-server-dev in Metaphor?

Ask the agent: "install the mcp-server-dev plugin". Metaphor downloads it from the signed catalog, checks the signature and checksum, and shows you what it can access before it turns on.

What can mcp-server-dev access?

It only adds instructions for the agent and does not run anything on your computer.

Which skills come with mcp-server-dev?

/build-mcp-app, /build-mcp-server, /build-mcpb. After installing, type one in the composer or describe the task and Metaphor picks the right skill.
