-# 🚀 Gusto MCP Server — 2026 Complete Version
+# 💼 Gusto MCP Server — HR & Payroll Intelligence
 
 ## 💡 What This Unlocks
 
-**This MCP server gives AI direct access to your entire Gusto workspace.** Instead of clicking through interfaces, you just *tell* it what you need.
+**This MCP server gives AI direct access to your Gusto HR and payroll data.** Stop manually exporting spreadsheets or hunting through dashboards. Ask Claude questions in plain English, and get instant answers.
 
-### 🎯 Gusto-Native Power Moves
+### 🎯 Gusto-Specific Power Moves
 
-The AI can directly control your Gusto account with natural language:
+| Use Case | What It Does | Tools Used |
+|----------|-------------|-----------|
+| **Headcount reporting** | Get current employee list with salaries, departments, roles | `list_employees`, `get_employee` |
+| **Payroll reconciliation** | Pull processed payrolls for a date range, verify amounts | `list_payrolls`, `get_payroll` |
+| **Contractor audit** | List all 1099 contractors and YTD payments | `list_contractors` |
+| **Benefits enrollment check** | See who's enrolled in health, 401k, etc. | `list_benefits`, `list_employees` |
+| **Company info export** | Get all company details, locations, tax IDs | `get_company` |
 
-- **Smart automation** — Complex workflows in plain English
-- **Data intelligence** — Query, analyze, and export your Gusto data
-- **Rapid operations** — Bulk actions that would take hours manually
-- **Cross-platform integration** — Combine Gusto with other tools seamlessly
+### 🔗 The Real Power: Natural Language HR Queries
 
-### 🔗 The Real Power: Combining Tools
+Instead of logging into Gusto and clicking around:
 
-AI can chain multiple Gusto operations together:
-
-- Query data → Filter results → Generate reports
-- Search records → Update fields → Notify team
-- Analyze metrics → Create tasks → Schedule follow-ups

+- *"What's our total payroll for Q4 2024?"*
+- *"List all contractors with payments over $10k this year"*
+- *"Who's enrolled in our health insurance plan?"*
+- *"Get company details including all locations"*
 
 ## 📦 What's Inside

 ## 🔐 Authentication
 
-See the official [Gusto API documentation](https://docs.gusto.com) for authentication details.
+Gusto uses **OAuth2** for authentication:
 
-The MCP server handles token refresh automatically.
+1. Go to [Gusto Developer Portal](https://dev.gusto.com/)
+2. Create a new **Partner Application**
+3. Configure OAuth redirect URIs
+4. Use the OAuth flow to obtain an **access token**
+5. Set `GUSTO_ACCESS_TOKEN` in your environment
+
+**Required Scopes:**
+- `employees:read`
+- `payrolls:read`
+- `contractors:read`
+- `company:read`
+- `benefits:read`
+
+**API Docs:** [https://docs.gusto.com/](https://docs.gusto.com/)
+
+**⚠️ Token Expiration:** Access tokens expire after a certain period. For production, implement token refresh using Gusto's OAuth refresh flow.

 ## 🐛 Troubleshooting
 
-### "Authentication failed"
-- Verify your API credentials are correct
-- Check that your API key hasn't been revoked
-- Ensure you have the necessary permissions
+### "Gusto API error: 401 Unauthorized"
+- Your access token is invalid or expired
+- Generate a new token through the OAuth flow
+- Verify you've set `GUSTO_ACCESS_TOKEN` correctly
+
+### "Gusto API error: 403 Forbidden"
+- Your OAuth application doesn't have the required scopes
+- Check your app's permissions in the Gusto Developer Portal
 
 ### "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)
+- Restart Claude Desktop after updating `claude_desktop_config.json`
+- Verify the path is **absolute** (no `~` or relative paths)
+- Check that `npm run build` completed successfully
+- Look for the `dist/index.js` file
+
+### "company_id required"
+- Most Gusto API calls require a `company_id` parameter
+- Get your company ID via the `get_company()` tool first
+- Or find it in your Gusto dashboard URL
