Connect MCPBundles on ChatGPT
For how MCP works in ChatGPT — connectors, developer mode, and remote MCP URLs — read How to Connect MCP Servers to ChatGPT.
This page covers connecting MCPBundles MCP servers only.
Requirements
- A ChatGPT plan that supports custom apps/connectors on the web (Plus, Pro, Business, Enterprise, or Education — see OpenAI’s current docs)
- An MCPBundles account and at least one MCP server Ready in your workspace
- Provider connections completed in MCPBundles (Connections on the server page)
Steps (match Quick Setup on the server page)
1. Prepare the MCP server in MCPBundles
- Open MCP Servers and select your server.
- Finish Connections until the header shows Ready.
- On Quick Setup, copy the MCP server URL (HTTPS, from MCPBundles — not localhost for hosted servers).
2. Enable Developer mode in ChatGPT
- In ChatGPT (web), go to Settings → Apps & Connectors → Advanced settings.
- Turn on Developer mode.
- Return to Apps & Connectors.
OpenAI renamed “Connectors” to “Apps” in late 2025; the flow is the same.
3. Create the app
- Click Create (or Create app).
- Set Name to match your MCP server (Quick Setup shows a suggested name).
- Set MCP Server URL to the URL you copied from MCPBundles.
- Set Authentication to OAuth when Quick Setup indicates OAuth (MCPBundles handles sign-in when ChatGPT connects).
- Save and complete any OAuth prompt from ChatGPT or MCPBundles.
ChatGPT talks to MCPBundles over the network; you do not run a local proxy for hosted servers.
MCPBundles-specific issues
| Symptom | Fix |
|---|---|
| Connector added but tools error | Open the server in MCPBundles; fix Needs attention items under Connections, then retry in ChatGPT. |
| URL rejected | Use the full HTTPS URL from Quick Setup, not a localhost address (unless you use Desktop for local servers). |
| Server still Needs setup | Connect every required provider on the MCP server page before testing in ChatGPT. |
