How to Register Your Findexar Upstream Connector as an App on ChatGPT

This guide walks you through registering your Findexar upstream connector as a ChatGPT App or Agent.

Prerequisites

  • A Findexar upstream connector (see Create an Upstream MCP Connector)
  • Access to ChatGPT (ChatGPT Plus or Enterprise)
  • MCP endpoint URL from your upstream connector

Understanding ChatGPT Apps and Agents

ChatGPT Apps and Agents are custom GPTs that users can create and share. They can:

  • Use custom tools and functions
  • Access external data and services
  • Provide specialized functionality
  • Be shared with other users

Findexar upstream connectors provide the MCP endpoint that ChatGPT connects to.

Step 1: Get Your MCP Endpoint URL

  1. Log in to your Findexar organization
  2. Navigate to your Upstream Connector
  3. Copy the MCP Endpoint URL - This is the URL you'll use in ChatGPT
  4. Save any API Keys or credentials if needed

Note: The MCP endpoint URL should look like: https://your-org.findexar.com/api/v1/flows/org/project/deployment/connector/mcp

Step 2: Access ChatGPT GPT Creation

  1. Log in to ChatGPT
  2. Navigate to Explore GPTs or Create a GPT
  3. Click Create to start creating a new GPT

Step 3: Configure Your GPT

Configure the basic settings for your GPT:

  1. Name - Give your GPT a name (e.g., "My Findexar App")
  2. Description - Describe what your GPT does
  3. Instructions - Provide instructions for how your GPT should behave
  4. Conversation Starters - Add example prompts users can try

Step 4: Add MCP Connection

Add your Findexar MCP endpoint:

  1. Navigate to Configure tab
  2. Scroll down to Actions or Tools section
  3. Click Add Action or Add Tool
  4. Select MCP or Custom API option
  5. Enter your MCP Endpoint URL from Step 1
  6. Add Authentication if required (API key, OAuth, etc.)

MCP Configuration

  • Endpoint URL - Your Findexar MCP endpoint URL
  • Authentication - OAuth 2.0 (automatic) or API key if needed
  • Tools - Tools should be automatically discovered from your upstream connector

Step 5: Configure Tools

Configure which tools to use:

  1. Available Tools - Review tools discovered from your MCP endpoint
  2. Select Tools - Choose which tools your GPT should use
  3. Tool Descriptions - Add descriptions for each tool to help ChatGPT understand when to use them
  4. Tool Parameters - Configure default parameters if needed

Step 6: Test Your GPT

Test your GPT to ensure it works:

  1. Switch to Preview tab
  2. Test Tool Calls - Try using tools to verify they work
  3. Test Authentication - Verify that user authentication works
  4. Test Billing - Verify that credits are deducted correctly (if applicable)

Step 7: Publish Your GPT

Once testing is complete, publish your GPT:

  1. Review Settings - Make sure all settings are correct
  2. Set Visibility - Choose who can access your GPT (Only me, Anyone with a link, Public)
  3. Publish - Click Publish to make your GPT available

Step 8: Share Your GPT

Share your GPT with users:

  1. Get Share Link - Copy the share link for your GPT
  2. Share with Users - Share the link with your target users
  3. Monitor Usage - Track usage and billing in your Findexar dashboard

Troubleshooting

Connection Issues

  • MCP endpoint not accessible - Check your Findexar connector status and deployment
  • Authentication failing - Verify authentication configuration in both Findexar and ChatGPT
  • Tools not discovered - Check that your upstream connector is properly configured

Tool Issues

  • Tools not working - Verify tool mapping and downstream connector status
  • Tool calls failing - Check tool parameters and server response format
  • Billing not working - Verify billing configuration and subscription plans

ChatGPT Issues

  • GPT not responding - Check GPT instructions and tool configurations
  • Tools not being used - Improve tool descriptions and GPT instructions
  • User access issues - Verify GPT visibility settings and user permissions

Next Steps

Now that your GPT is registered:

  1. Monitor Usage - Track usage and billing in your Findexar dashboard
  2. Gather Feedback - Collect user feedback to improve your GPT
  3. Iterate - Make improvements based on usage and feedback
  4. Scale - Add more tools or features as needed
