Connect ChatGPT to Odel modules via MCP
ChatGPT Setup
ChatGPT supports the Model Context Protocol (MCP) in developer mode, allowing you to connect your Odel modules. This guide shows you how to set it up.
Developer Mode Required
MCP support in ChatGPT requires developer mode. Make sure you have access to this feature before proceeding.
Prerequisites
- A ChatGPT account with developer mode access
- An Odel account with modules installed
Configuration
Enable Developer Mode
In ChatGPT, navigate to Settings → Developer Settings and enable developer mode if you haven't already.
Open MCP Configuration
In the developer settings, find the MCP Servers or External Tools section.
Add Your Modules
For each module you want to use, add a new MCP server:
| Field | Value |
|---|---|
| Name | A descriptive name (e.g., Calculator) |
| URL | The module's URL (e.g., https://mcp.odel.app/Odel/calculator-basic) |
| Transport | HTTP |
Find the module URL on the module's config page in the marketplace. Repeat this step for each module.
Save and Connect
Save your configuration. ChatGPT will attempt to connect to the Odel server.
Authenticate
When prompted, complete the OAuth flow to connect your Odel account. This gives ChatGPT access to your installed modules.
Verification
After setup, you can verify the connection by asking ChatGPT about available tools:
What Odel tools do you have access to?ChatGPT should list the tools from your installed Odel modules.
Using Odel Modules
Once connected, you can use your Odel modules naturally in conversation:
You: Use my email module to check for new messages
ChatGPT: I'll check your email using the Odel email module...
[Uses the email module tool]
You have 3 new messages:
1. From: team@example.com - "Weekly Update"
2. From: support@service.com - "Your ticket has been resolved"
...Tips for Best Results
- Be explicit — Mention "Odel" or the specific module name for clarity
- Check module docs — Review tool descriptions on the Odel marketplace
- Configure secrets — Ensure API keys are set up for modules that need them
Troubleshooting
Limitations

- Feature availability depends on your ChatGPT plan and developer mode access
- Some advanced MCP features may not be fully supported
- Authentication tokens may expire and require re-authentication
- Response times may vary based on ChatGPT's processing
