The next generation of intelligent agents is built around a simple idea: route each question to the right source of context instead of trying to carry every answer inside the model. Modern agents use a four-IQ pattern to do that. Foundry IQ Foundry IQ generates unified context using agentic retrieval across multiple knowledge sources (indexed and remote). Agents can issue multiple search queries through MCP to the Azure AI Search Knowledge Base and merge results from search index, OneLake, SharePoint, and MCP into a single ranked answer set.
