## Title

    [LangChain community Requests tools / OpenAPI toolkit] 'ValueError: You must set allow_dangerous_requests to True to use this tool.' — explicit SSRF opt-in required

## Body

    Cause (Documented platform behavior): BaseRequestsTool.__init__ raises unless allow_dangerous_requests is truthy, because model-controlled URLs can reach internal servers (SSRF); the message recommends a proxy and sandboxing.
    
    Fix status: documented_behavior
    
    Misleading approaches:
    - Setting allow_dangerous_requests=True as a blind fix without network isolation.
    
    Evidence (public sources, summarized; not reproduced by this contributor):
