MCP Reasoning Engine

# 🔗 How This Works with Claude ## Understanding the Setup Your API **already uses Claude AI** internally! Here's how it works: ``` Your API (Vercel) ↓ Uses Anthropic API ↓ Calls Claude AI ↓ Returns reasoning results ``` --- ## ⚠️ Important: You Need API Key Your API (`/reason` endpoint) needs `ANTHROPIC_API_KEY` to work because: 1. **User sends question** → Your API receives it 2. **Your API calls Claude** → Uses Anthropic API (needs API key) 3. **Claude processes** → Uses MCP tools (search, validate, evaluate) 4. **Returns result** → Structured reasoning output **Without the API key:** Step 2 fails → 500 error --- ## ✅ Two Ways to Use Claude ### Option 1: Your API Uses Claude (Current Setup) ⭐ **How it works:** - User → Your API → Claude AI → Response - Your API needs `ANTHROPIC_API_KEY` in Vercel **What you need:** - Set `ANTHROPIC_API_KEY` in Vercel environment variables - Your API will automatically use Claude **Best for:** - ✅ Production deployment - ✅ Client-facing demo - ✅ Permanent API --- ### Option 2: Claude Calls Your API (Alternative) **How it works:** - You → Claude Chat → Your API → Response - Claude can make HTTP requests to your API **What you need:** - Your API deployed (✅ already done!) - Claude can access the internet - You give Claude the API URL **Best for:** - Testing your API - Interactive exploration - Quick demos **Example with Claude Chat:** ``` You: "Call this API: https://mcp-iota-seven.vercel.app/reason with question: 'Is a verbal promise enforceable?'" Claude: [Makes POST request and returns the result] ``` --- ## 🎯 What You Need to Do ### To Make Your API Work with Claude: 1. **Get Anthropic API Key** - Go to [console.anthropic.com](https://console.anthropic.com/) - Create/get your API key 2. **Add to Vercel** - Vercel Dashboard → Your Project → Settings - Environment Variables → Add `ANTHROPIC_API_KEY` - Redeploy 3. **Test It** - Your API will now use Claude internally - `/reason` endpoint will work --- ## 💡 Using Claude Chat to Test Your API You can also ask Claude (this chat assistant) to test your API: ``` You: "Can you test this API endpoint? POST https://mcp-iota-seven.vercel.app/reason Body: {'question': 'Is a verbal promise enforceable?'}" ``` Claude can make the HTTP request and show you the results! --- ## 🔄 Summary | Setup | What Happens | API Key Needed? | |-------|--------------|-----------------| | **Your API → Claude** | API uses Claude internally | ✅ Yes (in Vercel) | | **Claude → Your API** | Claude calls your API | ❌ No (API is public) | **Current Status:** - ✅ Your API is deployed - ❌ API key not set in Vercel - ⚠️ `/reason` endpoint needs API key to use Claude **To Fix:** - Add `ANTHROPIC_API_KEY` to Vercel → Redeploy → ✅ Works! --- ## 🚀 Next Steps 1. **Get API key** from Anthropic 2. **Add to Vercel** environment variables 3. **Redeploy** 4. **Test** - Your API will use Claude successfully! --- **Bottom line:** Your API is already designed to use Claude! You just need to add the API key to Vercel so it can authenticate with Anthropic. 🔑
