OpenAI developer mode

[Arminova]

Hi

OpenAI recently added a developer mode to ChatGPT that allows us to use MCP. Unfortunately, there’s a blocking issue:

• ChatGPT Developer Mode only supports OAuth for MCP connections.
• MetaMCP, however, does not support OAuth for endpoints — only API keys.
• As a result, the only way to connect is by exposing MCP endpoints unprotected, which is a security risk.

Please add OAuth support to MCP endpoints.

There is already OAuth feature supported and I tested OpenAI, which version are you on? Check out the OAuth toggle on endpoint settings.

I am encountering this with sequential thinking and sequential thinking tool.

@zhjch05 how are you able to get pass this? When trying to create the mcp in connector I encounter:

This MCP server can't be used by ChatGPT to search information because it doesn't implement our specification: search action not found

For my own mcp, i had just implement the fetch and search...

I see. Then its ChatGPT's own requirement and some safety compliance we have to meet unfortunately..

I created a metamcp with hacker-news and seq thinking, and ask ChatGPT to list available tools.

I was able to get it to work with the /mcp endpoint. I also created a generic mcp with the search and fetch tool hoping to fill the gap, but does not seem to silence the error.
