Nothing to install if it's already active

If this skill is already added in your Claude, there's no need to install it again. Just ask for what you want to do.

Not sure? Ask Claude: "which skills do you have available?"

“Use the mcp-builder skill to help me design the structure of an MCP server connecting Claude to this API: …”

1 · The simplest way

Copy and paste into any AI chat

This skill runs scripts or reads local files: it won't work in a plain chat.

A plain chat can therefore only produce a partial result — the command line below remains the reliable path for this skill.

2 · Command line

/mcp-builder installs in 3 steps

For Claude Code. The skill installs on your computer and stays available across all your projects.

Prerequisites: Claude Code + Node.js

The skill runs inside Claude Code, Anthropic's AI assistant installed on your computer. Node.js is the engine that runs the install command. Both are free.

Install both (2 minutes)

Open PowerShell

Click Start, type "PowerShell", then press Enter.

Paste the command

Right-click inside the PowerShell window (or press Ctrl + V) to paste the command below, then press Enter. Wait a few seconds.

What the skill does

View the source code

In detail.

Hand it an API doc link. MCP-Builder produces the matching MCP server ready to plug into Claude. Built for technical profiles, but without hand-writing the code.

When to use it

You want Claude to drive an internal tool (CRM, ERP, in-house DB) or a third-party service without an official MCP.
