+# 🚀 FreshBooks MCP Server — 2026 Complete Version
+
+## 💡 What This Unlocks
+
+**This MCP server gives AI direct access to your entire FreshBooks workspace.** Instead of clicking through interfaces, you just *tell* it what you need.
+
+### 🎯 FreshBooks-Native Power Moves
+
+The AI can directly control your FreshBooks account with natural language:
+
+- **Smart automation** — Complex workflows in plain English
+- **Data intelligence** — Query, analyze, and export your FreshBooks data
+- **Rapid operations** — Bulk actions that would take hours manually
+- **Cross-platform integration** — Combine FreshBooks with other tools seamlessly
+
+### 🔗 The Real Power: Combining Tools
+
+AI can chain multiple FreshBooks operations together:
+
+- Query data → Filter results → Generate reports
+- Search records → Update fields → Notify team
+- Analyze metrics → Create tasks → Schedule follow-ups
+
+## 📦 What's Inside
+
+**82 API tools** covering the entire FreshBooks platform (Accounting).
+
+All with proper error handling, automatic authentication, and TypeScript types.
+
+## 🚀 Quick Start
+
+### Option 1: Claude Desktop (Local)
+
+1. **Clone and build:**
+   ```bash
+   git clone https://github.com/BusyBee3333/FreshBooks-MCP-2026-Complete.git
+   cd freshbooks-mcp-2026-complete
+   npm install
+   npm run build
+   ```
+
+2. **Get your FreshBooks API credentials** (see Authentication section below)
+
+3. **Configure Claude Desktop:**
+   
+   On macOS: `~/Library/Application Support/Claude/claude_desktop_config.json`
+   
+   On Windows: `%APPDATA%\Claude\claude_desktop_config.json`
+
+   ```json
+   {
+     "mcpServers": {
+       "freshbooks": {
+         "command": "node",
+         "args": ["/ABSOLUTE/PATH/TO/freshbooks-mcp/dist/index.js"],
+         "env": {
+           "FRESHBOOKS_API_KEY": "your-api-key-here"
+         }
+       }
+     }
+   }
+   ```
+
+4. **Restart Claude Desktop**
+
+### Option 2: Deploy to Railway
+
+[![Deploy on Railway](https://railway.app/button.svg)](https://railway.app/template/freshbooks-mcp)
+
+1. Click the button above
+2. Set your FreshBooks API credentials in Railway dashboard
+3. Use the Railway URL as your MCP server endpoint
+
+### Option 3: Docker
+
+```bash
+docker build -t freshbooks-mcp .
+docker run -p 3000:3000 \
+  -e FRESHBOOKS_API_KEY=your-key \
+  freshbooks-mcp
+```
+
+## 🔐 Authentication
+
+See the official [FreshBooks API documentation](https://docs.freshbooks.com) for authentication details.
+
+The MCP server handles token refresh automatically.
+
+## 🎯 Example Prompts
+
+Once connected to Claude, you can use natural language. Examples:
+
+- *"Show me recent activity in FreshBooks"*
+- *"Create a new record with these details..."*
+- *"Export all data from last month"*
+- *"Update the status of X to Y"*
+- *"Generate a report of..."*
+
+## 🛠️ Development
+
+### Prerequisites
+- Node.js 18+
+- npm or yarn
+- FreshBooks account with API access
+
+### Setup
+
+```bash
+git clone https://github.com/BusyBee3333/FreshBooks-MCP-2026-Complete.git
+cd freshbooks-mcp-2026-complete
+npm install
+cp .env.example .env
+# Edit .env with your FreshBooks credentials
+npm run build
+npm start
+```
+
+### Testing
+
+```bash
+npm test                  # Run all tests
+npm run test:watch        # Watch mode
+npm run test:coverage     # Coverage report
+```
+
+## 🐛 Troubleshooting
+
+### "Authentication failed"
+- Verify your API credentials are correct
+- Check that your API key hasn't been revoked
+- Ensure you have the necessary permissions
+
+### "Tools not appearing in Claude"
+- Restart Claude Desktop after updating config
+- Check that the path in `claude_desktop_config.json` is absolute
+- Verify the build completed successfully (`dist/index.js` exists)
