**Intelligent data parsing for AI agents via Model Context Protocol**

Transform any unstructured data into structured JSON using Parserator's revolutionary **Architect-Extractor pattern** - now available as a standardized MCP tool that any AI agent can use.

## 🚀 **What is this?**

The Parserator MCP Server exposes [Parserator's](https://parserator.com) intelligent parsing capabilities through the [Model Context Protocol (MCP)](https://modelcontextprotocol.io/), making it available to any AI agent that supports MCP.

### **Why MCP + Parserator?**

- **Universal Compatibility**: Works with Claude Desktop, LangChain, CrewAI, AutoGPT, and any MCP-compatible agent
- **Zero Vendor Lock-in**: MCP is an open standard - switch agents freely while keeping your parsing tools
- **Production Ready**: Built on Parserator's proven Architect-Extractor pattern with 95%+ accuracy
- **Token Efficient**: 70% fewer tokens than naive LLM prompting approaches

## 🏗️ **The Architect-Extractor Advantage**

Unlike simple "prompt an LLM to output JSON" approaches, Parserator uses a sophisticated two-stage process:

1. **🏛️ The Architect**: Plans the parsing strategy using a small data sample
2. **⚡ The Extractor**: Executes the plan on full data with surgical precision

**Result**: Higher accuracy, lower token costs, more reliable outputs.

## 📦 **Installation & Setup**

### **Quick Start**

```bash
# Install globally
npm install -g parserator-mcp-server

# Run with your API key
parserator-mcp-server pk_live_your_api_key_here
```

### **Get Your API Key**

1. Visit [parserator.com](https://parserator.com)
2. Sign up for free account
3. Generate API key from dashboard
4. Start with 1,000 free parses per month

### **Claude Desktop Integration**

Add to your `claude_desktop_config.json`:

```json
{
  "mcpServers": {
    "parserator": {
      "command": "npx",
      "args": ["parserator-mcp-server", "pk_live_your_api_key"],
      "description": "Intelligent data parsing for AI agents"
    }
  }
}
```

### **Other Agent Frameworks**

The MCP server works with any MCP-compatible system:

- **LangChain**: Use MCP tool integration

- **Custom Agents**: Standard MCP protocol

## 🛠️ **Available Tools**

### **`parse_data`** - Main Parsing Tool

Transform unstructured data into structured JSON:

```javascript
// Example: Email processing
{
  "inputData": "From: john@company.com\nSubject: Q4 Report Due\nHi team, please finish the quarterly report by Dec 15th.",
  "outputSchema": {
    "sender": "string",
    "subject": "string", 
    "deadline": "string",
    "priority": "string",
    "tasks": "string_array"
  },
  "instructions": "Extract actionable information"
}

// Result:
{
  "success": true,
  "parsedData": {
    "sender": "john@company.com",
    "subject": "Q4 Report Due",
    "deadline": "December 15th",
    "priority": "normal",
    "tasks": ["finish quarterly report"]
  },
  "metadata": {
    "confidence": 0.96,
    "tokensUsed": 245,
    "processingTime": 850
  }
}
```

### **`suggest_schema`** - AI-Powered Schema Generation

Let AI suggest the optimal structure for your data:

```javascript
{
  "sampleData": "John Smith, Senior Engineer, john@tech.com, (555) 123-4567"
}

// Result:
{
  "suggestedSchema": {
    "name": "string",
    "title": "string", 
    "email": "string",
    "phone": "string"
  },
  "confidence": 0.91
}
```

### **`validate_schema`** - Data Validation

Ensure parsed data matches expected structure:

```javascript
{
  "data": {"name": "John", "email": "john@email.com"},
  "schema": {"name": "string", "email": "string", "phone": "string"}
}

// Result:
{
  "valid": false,
  "errors": ["Missing required field: phone"],
  "suggestions": ["Add phone field or mark as optional"]
}
```

### **`test_connection`** - Health Check

Verify API connectivity and account status:

```javascript
// No parameters needed

// Result:
{
  "connection": "healthy",
  "latency": "245ms",
  "apiEndpoint": "https://app-5108296280.us-central1.run.app"
}
```
