Airtable MCP Server

# 🎯 Airtable MCP Server - Project Summary

## ✨ What We Built

A **Model Context Protocol (MCP) server for Airtable** that follows the same architectural pattern as your existing MCP servers (`asana-mcp` and `google-drive-mcp`). This server provides a standardized interface for AI-powered applications and n8n workflows to interact with Airtable.

## 🏗️ Architecture

### Core Components
- **`AirtableClientWrapper`** - Handles all Airtable API interactions
- **`tool_handler`** - Maps MCP tool calls to Airtable operations
- **HTTP Server** - Provides RESTful endpoints for MCP operations
- **TypeScript** - Full type safety and modern JavaScript features

### Design Pattern
Following your established MCP server pattern:
- **HTTP-based MCP protocol** instead of direct MCP SDK
- **Header-based authentication** (x-airtable-api-key, x-airtable-base-id)
- **Streaming responses** for real-time data
- **Render-ready deployment** configuration

## 🛠️ Available Tools (16 Total)

### Base Operations
- `get_base_info` - Get Airtable base information
- `list_tables` - List all tables in the base

### Table Operations  
- `get_table_info` - Get detailed table information
- `list_fields` - List all fields in a table
- `get_field_info` - Get detailed field information

### Record Operations
- `list_records` - List records with filtering, sorting, pagination
- `get_record` - Get a specific record by ID
- `create_record` - Create a new record
- `update_record` - Update an existing record
- `delete_record` - Delete a record

### Batch Operations
- `create_records` - Create multiple records (up to 10)
- `update_records` - Update multiple records (up to 10)
- `delete_records` - Delete multiple records (up to 10)

### View Operations
- `list_views` - List all views for a table
- `get_view_info` - Get detailed view information

## 🚀 Quick Start

### 1. Local Development
```bash
git clone <your-repo>
cd airtable-mcp
npm install
npm run dev:http
```

### 2. Test the Server
```bash
# Health check
curl http://localhost:3000/health

# List available tools
curl http://localhost:3000/tools
```

### 3. Deploy to Render
1. Fork the repository
2. Connect to Render
3. Deploy as Web Service
4. Set environment variables

## 🔌 n8n Integration

### HTTP Request Node Configuration
- **Method**: POST
- **URL**: `https://your-render-app.onrender.com/mcp`
- **Headers**:
  - `Content-Type: application/json`
  - `x-airtable-api-key: {{ $json.apiKey }}`
  - `x-airtable-base-id: {{ $json.baseId }}`
- **Body**: JSON-RPC 2.0 format

### Example n8n Workflow
1. **Set** node - Configure Airtable credentials
2. **HTTP Request** node - Call MCP tools
3. **Switch** node - Handle different responses
4. **Process** node - Format data for your needs

### Manual Testing
```bash
# Test individual endpoints
curl -X POST http://localhost:3000/mcp \
  -H "Content-Type: application/json" \
  -H "x-airtable-api-key: YOUR_API_KEY" \
  -H "x-airtable-base-id: YOUR_BASE_ID" \
  -d '{"method":"tools/list","params":{}}'
```
