Scope Selection Quick Reference

# Local (default) — private to you in this project
claude mcp add --scope local ...

# Project — shared with team via .mcp.json (never include credentials)
claude mcp add --scope project ...

# User — available across all your projects
claude mcp add --scope user ...

Rule of thumb:

• Anything with credentials → local
• Shared tools your whole team uses → project (store credentials in env vars, not in the config)
• Personal utilities you use everywhere → user

Security Checklist for MCP Servers

Before adding any MCP server to your workflow:

Before installing:
☐ Server is from a known organization or has verifiable open-source code
☐ You understand what data the server can read or modify
☐ Production/sensitive connections use read-only credentials

When configuring:
☐ Credentials passed via --env flags, not hardcoded in commands
☐ Database connections use a dedicated, least-privilege user
☐ Project-scope .mcp.json reviewed by team before committing

Ongoing maintenance:
☐ Update MCP server packages regularly
☐ Remove servers no longer in use: `claude mcp remove <name>`
☐ Rotate API keys used by MCP servers quarterly

Installing from Claude Desktop

If you have already configured MCP servers in Claude Desktop, import them to Claude Code:

claude mcp add-from-claude-desktop

Select which servers to import interactively. Works on macOS and WSL.

Building Your Own

When no existing server meets your needs, build a custom MCP server. See Chapter 14 — Building Custom MCP Servers in Book 2.

Quick-start template:

# 1. Initialize project
mkdir my-mcp-server && cd my-mcp-server
npm init -y
npm install @modelcontextprotocol/sdk zod

# 2. Create server.js
cat > server.js << 'EOF'
import { McpServer } from "@modelcontextprotocol/sdk/server/mcp.js";
import { StdioServerTransport } from "@modelcontextprotocol/sdk/server/stdio.js";
import { z } from "zod";

const server = new McpServer({ name: "my-server", version: "1.0.0" });

server.tool(
  "my_tool",
  "Description of what this tool does",
  { input: z.string().describe("The input parameter") },
  async ({ input }) => ({
    content: [{ type: "text", text: `Processed: ${input}` }]
  })
);

await server.connect(new StdioServerTransport());
EOF

# 3. Register with Claude Code
claude mcp add --transport stdio my-server -- node server.js
