ChatGPT Quickstart

This guide walks you through connecting ChatGPT to your autoGMS Garage so you can manage your shop through conversation.

Prerequisites

• A ChatGPT Plus or Team subscription with MCP support.
• An autoGMS account on a Pro or Business plan.
• Membership in at least one Team and Garage.

Step 1: Get Your MCP URL

1. Log in to autoGMS.
2. Navigate to your Garage dashboard.
3. Go to Settings → MCP.
4. Copy the MCP endpoint URL:

   https://your-domain.com/api/mcp?workspace=my-team&project=my-garage

Step 2: Add the MCP Server in ChatGPT

1. Open ChatGPT.
2. Go to Settings → Connected Apps (or the MCP configuration section).
3. Click Add MCP Server.
4. Paste your autoGMS MCP URL.
5. Authorize with OAuth when prompted. The autoGMS endpoint is protected by OAuth 2.1 and accepts Bearer tokens only (no cookie/browser-session fallback). ChatGPT discovers the authorization server from /.well-known/oauth-protected-resource, dynamically registers itself (no client ID/secret to enter), then sends you to sign in at autoGMS (/auth/sign-in) and approve access on the /consent screen. ChatGPT then stores the Bearer access token for all requests.

Step 3: Verify

Ask ChatGPT:

"List my bookings for this week"

If you see your bookings, the connection is working.

Example Prompts

• "Search for customer Sarah Connor"
• "Create a new expense for $50 for shop supplies"
• "What is the profit and loss for last month?"
• "Create a booking for the vehicle with plate XYZ-789"

If Something Goes Wrong

• No MCP option in ChatGPT — MCP support requires ChatGPT Plus or Team. Verify your subscription.
• Authentication errors — Your Bearer access token is missing, invalid, or expired. Reconnect the server in ChatGPT to re-run the OAuth sign-in and consent flow and obtain a fresh token.
• Feature gated — Ensure your Team is on a Pro or Business plan.
