Get web-connected AI responses from Perplexity
AI agents call get_perplexity_opinion to retrieve information from Second Opinion MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves responses/opinions from Perplexity AI, a read-only operation that fetches information. It queries an external AI service and returns results without creating, modifying, or deleting any data. The 'web-connected' aspect means it searches the web to inform its response, but this is still a retrieval operation with no side effects.
