ChatGPT, Claude.ai and other OAuth connectors
MegaLens works with any tool that supports OAuth MCP connectors, such as ChatGPT and Claude.ai. You paste one URL, sign in to MegaLens and approve. There is no token to copy. Your first review is free and you do not need a card.
What this does, and what it does not
MegaLens reviews the code the chat sends it. When you ask for a review, the assistant passes the code to MegaLens. MegaLens selects AI models from different companies to read it and reports where they agree and where they disagree.
MegaLens cannot open your files. It only sees the code the assistant sends in that message. Paste the code into the chat, or attach the file, and ask for the full code to be sent.
The app acts as you on MegaLens. Reviews it runs use your free review, your credits or your plan. You can disconnect it at any time from MCP Setup in your MegaLens account.
Connect it
1. Add MegaLens as a connector
Use this URL exactly as it is:
https://megalens.ai/api/mcp
- ChatGPT: turn on developer mode first. On Business and Enterprise, a workspace admin turns it on in Workspace settings. Then create a new app or connector, paste the URL and choose OAuth. In a new chat, pick MegaLens from the tools menu.
- Claude.ai: Settings, then Connectors, then Add custom connector. Paste the URL and leave the client ID blank.
- Other apps: add a custom MCP connector that signs in with OAuth, and paste the URL.
2. Sign in and approve
The app opens a MegaLens page. Sign in, or create an account. You then see which app is asking and the address it will return to. If that is the app you are using, press Approve. You go back to the app, connected.
3. Ask for a review
Type this in the chat:
“Use MegaLens to review this code. Send it the full code, not just file names.”
If the app asks whether to allow the MegaLens tools, allow them. One review makes several calls: it starts the review, then checks for the result. A review takes a few minutes.
Your first review is free
It works here too, with no card. MegaLens selects two reviewing models for the free review.
After that you can buy prepaid pay as you go credits, or save your own OpenRouter key on Pro. Apps connected this way cannot send your OpenRouter key with each request, the way an editor config can, so a saved key on Pro or credits are the two ways to keep going. Both are on your billing page.
If something does not work
The app says it cannot connect
Check the URL has nothing added to it, then try again. If you pressed Deny by mistake, remove MegaLens from the app and add it again.
You disconnected it and want it back
Remove MegaLens from the app, add it again and approve it.
It is still not working
Email [email protected] and say which app you used and what came back.
