ApexVol MCP server for ChatGPT
The same server,
in ChatGPT.
MCP is an open standard. ChatGPT accepts remote MCP servers as custom connectors, so the URL that connects Claude connects ChatGPT too.
The hosted server, recommended
Connected with
one URL.
ApexVol runs the server. ChatGPT signs in to your ApexVol account through the browser, so nothing is installed and no token is copied anywhere.
- In ChatGPT open Settings, then Connectors, then Advanced, and turn on Developer mode.
- Choose Create. Name it ApexVol, paste https://apexvol.com/mcp-server as the MCP server URL, and pick OAuth for authentication.
- ChatGPT sends you to apexvol.com. Sign in and approve the read-only request.
- In a new chat, enable the ApexVol connector and ask: what is SPY's IV rank?
https://apexvol.com/mcp-serverIs NVDA's earnings straddle overpriced compared with how much the stock usually moves?
ChatGPT calls the tool and answers from live data.- Read-only. The connector can read options analytics on your behalf and nothing else. It cannot see billing or change your account.
- Use the apex form of the URL, apexvol.com without www. The www form fails the audience check on purpose.
- Approving creates a token you can see and revoke under Account, then API Access.
- Custom MCP connectors in ChatGPT are available on its paid plans and require developer mode to be switched on.
The local client, for developers
Or run it
on your machine.
ChatGPT connects to remote servers only, so the hosted connector is the route. The local apexvol-mcp client is for editors and the Claude apps.
Tokens are created under Account, then API Access, shown once, and rotate in one click if one ever leaks. The same token calls the REST API from your own code.

Questions
Before you
paste the URL.
Does the ApexVol MCP server work with ChatGPT?
Yes. ChatGPT supports remote MCP servers as custom connectors. Add one in developer mode with the same URL Claude uses, sign in on apexvol.com, and the 43 tools are available in chat.
Which ChatGPT plans allow custom connectors?
ChatGPT's paid plans, with developer mode enabled under Settings, then Connectors, then Advanced. The ApexVol side is included with every paid ApexVol plan.
Can ChatGPT run the local apexvol-mcp client?
No. ChatGPT does not start local processes, so the hosted server is the only route. The local client is for Claude Desktop, Claude Code, Cursor, VS Code, Windsurf and Gemini CLI.
Is my ApexVol login shared with OpenAI?
No. ChatGPT receives an access token scoped to read options analytics, issued after you approve on apexvol.com. Your password never leaves apexvol.com, and the token can be revoked under Account, then API Access.
