Claude Services

Production-ready MCP servers for Claude Code — give Claude the tools to browse, read, write, and reason beyond its defaults.

MCP servers extend what Claude can do — not just what it knows. Install a service and Claude gains new capabilities it can use autonomously: controlling a real browser, reading and writing files, structuring its reasoning step by step.

How Services Work

Each service is an MCP (Model Context Protocol) server that Claude Code connects to as an external process. Once installed, Claude picks up the new tools automatically — no extra prompting required.

Requirements

• Node.js with npx (node)
• Claude Code (claude)

macOS (Homebrew):

brew install node

Nix:

nix profile install nixpkgs#nodejs

Install claude separately: Claude Code installation guide

Quickstart

1. Register the marketplace in ~/.claude/settings.json:

{
  "extraKnownMarketplaces": {
    "claude-services": {
      "source": {
        "source": "github",
        "repo": "claude-contrib/claude-services"
      }
    }
  }
}

2. Install a service inside Claude Code:

/plugin install playwright@claude-services

Claude now has browser automation tools available in every session.
