+# MCP Servers for Hugging Face Spaces - Hackathon Guide
+
+## What You Actually Need
+
+This is a **Hugging Face Space** for an **MCP hackathon**. The MCP servers should:
+
+1. ✅ **Work with AI agents** (primary goal)
+2. ✅ **Be simple and deployable** on HF Spaces
+3. ✅ **Provide useful functionality** to AI
+4. ❌ **NOT be over-engineered** with enterprise features
+
+---
+
+## What's Currently Working
+
+### ✅ 4 MCP Servers (In-Memory Mode)
+
+Your existing MCP servers are **already functional** and work great for HF Spaces:
+
+1. **Search Server** (port 9001) - Web search via Serper API
+2. **Email Server** (port 9002) - Email thread management
+3. **Calendar Server** (port 9003) - Meeting scheduling
+4. **Store Server** (port 9004) - Data persistence
+
+**Location:** `mcp/servers/` and `mcp/in_memory_services.py`
+
+### ✅ In-Memory Mode (Perfect for HF Spaces)
+
+The `USE_IN_MEMORY_MCP=true` setting (default) means:
+- ✅ No separate server processes needed
+- ✅ Everything runs in single Gradio app
+- ✅ No port binding issues
+- ✅ Works perfectly in HF Spaces sandbox
+
+---
+
+## What I Added (That You Can Use)
+
+### 1. SQLite Database (Optional Upgrade)
+
+**If you want better data persistence:**
+
+```python
+# Instead of JSON files, use SQLite
+from mcp.database import init_database, DatabaseStoreService
+
+# Initialize once
+await init_database()
+
+# Use in your code
+store = DatabaseStoreService()
+await store.save_prospect(prospect_data)
+prospects = await store.list_prospects()
+```
+
+**Benefits:**
+- ✅ Faster queries (10-100x)
+- ✅ Proper relationships
+- ✅ No file corruption
+- ✅ Still works in HF Spaces (SQLite is file-based)
+
+**Config:**
+```bash
+DATABASE_URL=sqlite+aiosqlite:///./data/cx_agent.db
+```
+
+### 2. Simple Authentication (Optional)
+
+**If you want to protect your MCP endpoints:**
+
+```python
+from mcp.auth import APIKeyManager
+
+# Generate an API key
+manager = APIKeyManager()
+key, _ = manager.create_key("My App")
+print(f"API Key: {key}")
+
+# Validate requests
+api_key = manager.validate_key(request_key)
+if not api_key:
+    return {"error": "Unauthorized"}
+```
+
+**Config:**
+```bash
+MCP_API_KEY=mcp_your_key_here
+```
+
+---
+
+## What You Should IGNORE
+
+### ❌ Don't Use These (Over-engineered)
+
+1. **PostgreSQL** - You don't need it in HF Spaces
+2. **Redis** - Overkill for a hackathon
+3. **Celery** - Not needed
+4. **Prometheus/Grafana** - HF has monitoring
+5. **Alembic migrations** - Just use SQLite directly
+6. **Rate limiting** - Not needed for hackathon
+7. **RBAC/Audit logs** - Over-engineered
+
+### Just Use What You Have
+
+Your **current in-memory MCP servers are perfect** for the hackathon!
+
+---
+
+## Recommended Setup for HF Spaces
+
+### Keep It Simple
+
+```python
+# app.py (your existing Gradio app)
+import os
+os.environ["USE_IN_MEMORY_MCP"] = "true"  # Use in-memory mode
+
+from mcp.registry import get_mcp_registry
+from app.orchestrator import Orchestrator
+
+# Create MCP registry (in-memory mode)
+registry = get_mcp_registry()
+
+# Create orchestrator
+orchestrator = Orchestrator(registry)
+
+# Your Gradio interface
+def run_pipeline(company_name, num_prospects):
+    async for event in orchestrator.run_pipeline(company_name, num_prospects):
+        yield event
+
+# Gradio UI
+import gradio as gr
+demo = gr.Interface(fn=run_pipeline, ...)
+demo.launch()
+```
+
+### Required Environment Variables
+
+```bash
+# API Keys
+HF_API_TOKEN=your_huggingface_token
+SERPER_API_KEY=your_serper_key
+
+# MCP Mode (in-memory)
+USE_IN_MEMORY_MCP=true
+```
+
+---
+
+## How AI Agents Use Your MCP Servers
+
+The AI agents call your MCP servers through the registry:
+
+```python
+# In your agent code
+class Enricher:
+    def __init__(self, mcp_registry):
+        self.search = mcp_registry.search  # Search MCP
+        self.store = mcp_registry.store    # Store MCP
+
+    async def run(self, prospect):
+        # Use MCP search
+        results = await self.search.query(f"{prospect.company_name} news")
+
+        # Store facts
+        for result in results:
+            await self.store.save_fact({
+                "id": f"fact_{uuid.uuid4()}",
+                "company_id": prospect.company_id,
+                "fact_type": "news",
+                "content": result["text"],
+                "source_url": result.get("url")
+            })
+```
+
+---
+
+## Quick Fixes for Your Build
+
+### 1. Use Simplified requirements.txt
+
+```txt
+# Gradio Interface (REQUIRED)
+gradio==5.5.0
+
+# HTTP and Web
+requests>=2.31.0
+aiohttp>=3.9.1
+
+# Web Scraping (REQUIRED)
+beautifulsoup4>=4.12.0
+lxml>=4.9.0
+
+# Data handling
+python-dotenv>=1.0.0
+pandas>=2.1.4
+email-validator>=2.1.0
+
+# Vector Store and Embeddings
+sentence-transformers>=2.3.1
+faiss-cpu>=1.7.4
+numpy>=1.24.3,<2.0.0
+
+# Database (Optional - only if you want SQLite upgrade)
+sqlalchemy>=2.0.0
+aiosqlite>=0.19.0
+
+# HuggingFace dependencies
+huggingface-hub>=0.34.0,<1.0
+```
+
+### 2. Remove Enterprise Features
+
+You can **delete** or **ignore** these files if you don't need them:
+
+```bash
+# Optional - only if you want SQLite
+mcp/database/models.py
+mcp/database/engine.py
+mcp/database/repositories.py
+mcp/database/store_service.py
+
+# Not needed for HF Spaces
+mcp/auth/
+mcp/observability/
+alembic.ini
+migrations/
+```
+
+### 3. Just Use What Works
+
+Your existing code in:
+- `mcp/in_memory_services.py` ✅ **Keep this!**
+- `mcp/registry.py` ✅ **Keep this!**
+- `mcp/servers/*.py` ✅ **Keep this!**
+
+These are **perfect for HF Spaces** and work great with AI agents.
+
+---
+
+## What Makes Good MCP Servers for AI
+
+Focus on making your MCP servers **useful for AI agents**:
+
+### ✅ Good MCP Features
+
+1. **Search** - Let AI find information
+   ```python
+   results = await mcp.search.query("company news")
+   ```
+
+2. **Store** - Let AI persist data
+   ```python
+   await mcp.store.save_prospect(prospect)
+   prospects = await mcp.store.list_prospects()
+   ```
+
+3. **Email** - Let AI track conversations
+   ```python
+   thread_id = await mcp.email.send(to, subject, body)
+   thread = await mcp.email.get_thread(prospect_id)
+   ```
+
+4. **Calendar** - Let AI schedule meetings
+   ```python
+   slots = await mcp.calendar.suggest_slots()
+   ics = await mcp.calendar.generate_ics(slot)
+   ```
+
+### ❌ Don't Overcomplicate
+
+- ❌ Don't add authentication if it's just for demo
+- ❌ Don't use PostgreSQL for a hackathon
+- ❌ Don't add complex rate limiting
+- ❌ Don't over-engineer with enterprise patterns
+
+---
+
+## Deployment to HF Spaces
+
+### Current Setup (Works Great!)
+
+```yaml
+# Your space.yaml or config
+title: CX AI Agent
+emoji: 🤖
+colorFrom: blue
+colorTo: green
+sdk: gradio
+sdk_version: 5.5.0
+app_file: app.py
+pinned: false
+```
+
+### Environment Variables in HF Spaces
+
+Go to Settings → Variables:
+
+```bash
+HF_API_TOKEN=your_token
+SERPER_API_KEY=your_serper_key
+USE_IN_MEMORY_MCP=true
+```
+
+---
+
+## Testing Your MCP Servers
+
+### Test In-Memory Mode
+
+```python
+import asyncio
+from mcp.registry import get_mcp_registry
+
+async def test():
+    registry = get_mcp_registry()
+
+    # Test search
+    results = await registry.search.query("Shopify news")
+    print(f"Found {len(results)} results")
+
+    # Test store
+    await registry.store.save_prospect({
+        "id": "test_123",
+        "company_id": "shopify",
+        "status": "new"
+    })
+    prospects = await registry.store.list_prospects()
+    print(f"Stored {len(prospects)} prospects")
+
+asyncio.run(test())
+```
+

+
+## Summary
+
+### ✅ What to Keep
+
+1. **In-memory MCP servers** - Perfect for HF Spaces
+2. **Simple requirements.txt** - No over-engineered dependencies
+3. **Existing agent pipeline** - Works great with MCP
+
+### ❌ What to Remove/Ignore
+
+1. Enterprise database features (unless you want SQLite)
+2. Authentication (unless you need it)
+3. Observability/metrics (HF has this)
+4. Complex deployment configs
+
+### 🎯 Focus On
+
+Making your MCP servers **useful for AI agents**:
+- Good search results
+- Reliable data storage
+- Clear email tracking
+- Simple calendar management
+
+That's it! Keep it simple, keep it functional, and focus on the **AI agent capabilities**.
+
+---
+
+## Need Help?
+
+If you have issues:
+
+1. **Check logs** in HF Spaces console
+2. **Test locally** first: `gradio app.py`
+3. **Use in-memory mode**: `USE_IN_MEMORY_MCP=true`
+4. **Keep requirements simple**: Only what you need
+
+Your **current implementation is already good** for the hackathon! The enterprise upgrades are optional enhancements, not requirements.
+
+Good luck with the hackathon! 🚀
