[Support]: Find the function definitions of installed MCP servers.

[Te-eMster]

What features would you like to see added?

Where can I find the function definitions of the installed MCP servers? How are they derived?

I installed duckduckgo-mcp-server via smithery on my freshly installed local LibreChat instance (https://smithery.ai/server/@nickclyde/duckduckgo-mcp-server). I also tried to install it via uvx, but the result was the same.

In the docs, it states that the "max_results" parameter in the search-function is defined as an integer. However, when I invoke this function in the prompt, the llama-cpp-logs (running llama-cpp-server with GPT-OSS-120b) tell me that the call mentions has definition:
"max_results":{"anyOf":[{"anyOf":[{"not":{}},{}]},{"type":"null"}

I can neither find the equivalent in the duckduckgo-mcp-server docs nor in the repo (https://github.com/nickclyde/duckduckgo-mcp-server/blob/main/src/duckduckgo_mcp_server/server.py).
