It's not that hard to roll your own web search MCP.

I made one for Crush a while ago.

I'm not sure about the issues with reddit though? Do they block Claude's web fetch tool? I think Codex runs it thru some kind of cache proxy.

Rolling your own is not the solution for the common case where you’re asking an LLM a question that may or may not be supported or supplemented by a web search. ChatGPT decides by itself when and how to consult the web, and then links the relevant sources in its result. You don’t get that functionality from Claude chat, you’d have to completely build your own chat harness and apps.

Sites like Reddit are blocking AI providers, they have to have some contract with them for access. OpenAI does seem to have that.
