SourceWizard – AI Setup Wizard That Installs SDKs for You

TL;DR

TL;DR: SourceWizard is an open-source CLI that uses AI to install and configure SDKs — handling middleware, env vars, and multi-package setup — so you stop reading READMEs and stop configuring manually.

What Is SourceWizard?

SourceWizard is an open-source CLI tool that combines AI-powered package search with automated installation and configuration. It was built to solve a real developer pain point: setting up SDKs correctly takes time, and “AI coding agents like Cursor and Claude often hallucinate or use deprecated API calls” when working without context.

From the official README:

“AI-powered setup wizard for dev tools and libraries with MCP (Model Context Protocol) integration.”

The tool works as a standalone CLI and also as an MCP server, meaning it can be integrated directly into Claude Code, Cursor, and other MCP-compatible editors.

Setup Workflow

Prerequisites

• Node.js 18 or later
• npm or npx
• Optional: API key from sourcewizard.ai/dashboard for cloud features

Step 1: Install the CLI

npm install -g @sourcewizard/sourcewizard

Or run directly with npx:

npx @sourcewizard/sourcewizard install <package-name>

Step 2: Install a Package with AI Guidance

# Search for packages with natural language
sourcewizard search "react testing library"

# Install and configure a package
sourcewizard install clerk

Step 3: Set Up MCP Integration

SourceWizard works as an MCP server, giving your AI coding agent real-time, up-to-date package documentation. Add this to your MCP settings file (for example, ~/.config/claude-code/mcp_settings.json):

{
  "mcpServers": {
    "sourcewizard": {
      "command": "npx",
      "args": ["sourcewizard", "mcp"],
      "env": {
        "SOURCEWIZARD_API_KEY": "your-api-key-here"
      }
    }
  }
}

Available MCP tools:

• search_packages — AI-powered package and code snippet search
• install_package — install and configure packages with AI guidance

Step 4: Repository Analysis

# Analyze repository structure
sourcewizard repo [path]

# Build the entire project
sourcewizard build

# Run tests for a specific target
sourcewizard test //sourcewizard:sourcewizard

Deeper Analysis

The Problem It Solves

Setting up a new SDK typically involves: reading the README, installing the package, configuring middleware, setting env vars, and handling edge cases. This is tedious and repetitive. SourceWizard automates the entire chain by combining package search, AI-guided install, and automated configuration in one command.

MCP Integration

The MCP (Model Context Protocol) integration is the most interesting part for AI coding workflows. Instead of an AI agent guessing at API calls or reading outdated docs, SourceWizard provides a real MCP tool that returns current, accurate package information. From the README:

“No hallucinated or deprecated API calls.”

This is a meaningful improvement over the baseline problem many AI coding agents have with third-party SDKs.

Supported Packages

The tool currently supports a growing list of packages. The HN launch demo showed clerk as the example (npx ai-setup clerk), but the tool is designed to work with any package that has a known setup flow.

Practical Evaluation Checklist

• Does it install correctly? Run sourcewizard install <package> and verify the package is installed and configured
• Does MCP tool return accurate results? Query search_packages and verify the returned information matches current package docs
• Does it handle errors gracefully? Test with a non-existent package and verify a clear error message
• Is the terminal UI clear? The tool shows progress tracking during installation
• Does it integrate with Claude Code / Cursor? Requires MCP client setup — verify your editor supports MCP

Security Notes

• The SOURCEWIZARD_API_KEY is required for cloud AI features. Keep it in your environment variables, not hardcoded.
• The tool reads your package.json and repository structure — it does not send your codebase to external servers except when using the cloud API key for AI features.
• Local MCP mode can be used without an API key for basic package installation.

FAQ

Q: Is this related to the PostHog Install AI Wizard? A: SourceWizard is similar in concept to PostHog’s Install AI Wizard but supports a broader range of packages and works as a standalone CLI and MCP server.

Q: Does it work with all npm packages? A: The tool uses AI to generate setup flows. It works best with packages that have standard installation patterns. Some complex packages may require manual configuration.

Q: What package managers does it support? A: Primarily npm/node.js packages. The tool detects your repository structure and runs appropriate commands.

Q: Is an API key required? A: No — basic CLI features like sourcewizard install work without an API key. AI-powered search and cloud features require an API key from sourcewizard.ai/dashboard.

Conclusion

SourceWizard solves a real friction point in developer workflows: the gap between “install a package” and “actually have it configured correctly.” Its MCP integration is particularly valuable for AI coding workflows where agents need accurate, current package information. The open-source Apache 2.0 license means you can inspect, modify, and contribute to the tool.

If you spend time configuring SDKs manually or debugging AI agent SDK mistakes, SourceWizard is worth a try. Start with npx @sourcewizard/sourcewizard install <package> and see how it handles your next setup.
