How do I install the sdd mcp server?

Run it through your MCP client's configuration using `npx -y npm`. Add the server block to Claude Desktop's config file (or use `claude mcp add` for Claude Code), restart the client, and the tools appear automatically. Full snippets are on this page.

Does the sdd mcp server need an API key?

No API key is documented for this server, so it should start without additional credentials. Because it runs locally, it inherits whatever access your machine already has — worth keeping in mind when you decide what to point it at.

What is the SDD MCP MCP server?

MCP Server providing Seam-Driven Development tools for AI-assisted software development. The sdd mcp mcp server wraps that behind the Model Context Protocol, so an assistant can use it rather than through you.

What it actually does

A Model Context Protocol (MCP) server that provides AI assistants with Seam-Driven Development (SDD) tools for structured software development. The foundation is complete - now it's time to build amazing projects with these proven tools!

The SDD MCP Server automates the proven Seam-Driven Development workflow:

Adding it to your client

Installation goes through your MCP client rather than a global install: point it at npm on npm and it is fetched when the client starts. The copy-paste blocks for Claude Desktop, Claude Code and Cursor are further down this page.

When to reach for it

Plenty of developer tooling servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. It is maintained by Phazzie; worth a glance at recent repository activity before you build anything load-bearing on it.

SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.

Caveats

It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
MCP clients confirm each tool call by default. Leave that on until you have watched what the sdd mcp mcp server does with a few real requests.
