Is mcp-builder safe to install?

Review the source first

Review the source first: our audit of mcp-builder's source files found 7 shell commands, 1 external URL, file reads and writes (high risk). Every command and URL listed appears verbatim in the skill's source. The skill executes shell commands and makes network requests to local MCP server endpoints for testing and development purposes.

How we audit skills: our security review methodology.

# IMPORTANT: How to Use This Skill

This file provides a NAVIGATION GUIDE ONLY. Before implementing any MCP server features, you MUST:

1. Read this overview to understand which reference files are relevant
2. **ALWAYS read the specific reference file(s)** for the features you're implementing
3. Apply the detailed patterns from those files to your implementation

**Do NOT rely solely on the quick reference examples in this file** - they are minimal examples only. The reference files contain critical best practices, security considerations, and advanced patterns.

Frequently asked questions

How do I start a new MCP project?

Use the command 'npx create-mcp-use-app <project-name>' to scaffold a new project.

How can I test my MCP server tools without a UI?

Use the 'mcp-use client' CLI to connect to your server and execute tools directly from the terminal.

Where should I look for authentication implementation details?

Consult the 'references/authentication/' directory, which contains guides for providers like Auth0, Clerk, Supabase, and others.

What is the recommended way to handle errors in tools?

Use the 'error()' response helper instead of throwing exceptions to ensure graceful error handling.
