How to set up a remote MCP server and connect it to ChatGPT deep research

I had a similar issue a few days ago. For me, it was a missing query parameter, so you probably have issues somewhere in the input schema as well.

What I have found so far regarding ChatGPT MCP requirements:

  • It is still in beta, so expect issues and breaking changes.
  • The closest thing to MCP integration requirements is this OpenAI documentation article.
  • MCP must have search and fetch tools with the correct schema. It may be just a mock implementation, but it must be present.
  • All naming must be snake_cased.
