What Mcp Server Dev is
Mcp Server Dev is a plugin published in the anthropics/claude-plugins-official repository on GitHub, which has about 37.1k stars. The repository describes itself as: “Official, Anthropic-managed directory of high quality Claude Code Plugins.”
A plugin is a package that bundles skills, slash commands, subagents, hooks, and MCP connectors so they install together. Plugins are plain files with a manifest at .claude-plugin/plugin.json, and they work in both Claude Code and Claude Cowork.
Installing Mcp Server Dev adds everything it ships in one step. Connectors inside a plugin still need to be connected separately, and hooks and subagents only run in Cowork and Claude Code, not in regular chat.
How to install Mcp Server Dev
Claude Code
- Add the repository as a plugin marketplace: claude plugin marketplace add anthropics/claude-plugins-official
- Install the plugin: claude plugin install mcp-server-dev@<marketplace-name>, using the marketplace name from the repository's .claude-plugin/marketplace.json.
- Restart the session if the new skills or commands don't appear straight away.
Claude Cowork
- Open Customize → Plugins and choose Add marketplace.
- Enter anthropics/claude-plugins-official (the owner/repo shorthand works for GitHub).
- Find Mcp Server Dev in the list, click Install, then connect any connectors it needs from its Connectors tab.

What's inside
Three skills that compose into a full build path:
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-serverBefore you install
- Read the whole file first. Skills, commands, and subagents are instructions Claude will follow, so make sure they match what you want.
- Check which tools, scripts, or MCP servers it uses. Local servers and scripts run with your permissions.
- Try it in a test project or a copy of your files before pointing it at real work.
- Pin the version you tested, and review changes before updating.
- Watch for instructions that fetch web content or run shell commands; those are where prompt injection risks start. See our prompt injection guide.
