Overview
Infrastructure for connecting AI agents to external tools, data sources, and services via standardized protocols. The Model Context Protocol (MCP), introduced by Anthropic in November 2024, became the de facto standard for AI-tool integration by 2026. Donated to the Agentic AI Foundation (Linux Foundation), co-founded with Block and OpenAI. 2026 roadmap focuses on four priorities: transport scalability (horizontal scaling without state), enterprise readiness (OAuth 2.1 with PKCE for Q2, SAML/OIDC integration), agent communication, and governance maturation. MCP adopted by all major platforms (ChatGPT, Cursor, Gemini, Copilot, VS Code). 10,000+ active servers, 97M+ monthly SDK downloads, 50+ enterprise partners.
