# Dual Model MCP Server

> Use this tool when you need to generate multi-perspective responses to a query, leveraging the strengths of both Claude Sonnet 4.6 and OpenAI GPT-5.5 models in parallel. It solves problems requiring diverse viewpoints and cross-validation, taking in natural language queries as input and returning structured comparative responses as output. Ideal for use cases where a single model's limitations may lead to biased or incomplete results.
