What is the Model Context Protocol (MCP)?

Model Context Protocol (MCP) is presented as a crucial emerging specification for managing how AI models access enterprise data across multiple applications. It addresses the security and permission challenges arising from AI's ability to interact with diverse data sources by ensuring models operate with proper identity, access rights, and full auditability. MCP acts as an "operating system" for AI data access, enforcing rules, tracking user requests, filtering visible data, orchestrating complex actions, and logging all activity. The increasing reliance on API-based data requests in AI-forward organizations highlights the necessity of MCP to prevent data leaks and ensure secure AI workflows. Introduced in late 2024, MCP has rapidly gained adoption by major industry players and is projected to become a foundational standard for enterprise AI integrations.
