What is MCP and why does it matter for enterprise AI agents?

MCP, the Model Context Protocol, is a standard for exposing tools to AI agents as a declarative surface. Instead of every agent integrating against every system through bespoke code, the system publishes its tools through MCP and the agent discovers and calls them through a single protocol. For enterprise rollouts, MCP matters because tool boundaries become enforceable. You grant an agent access to specific tools rather than to whole systems, and you can revoke access without rewriting the agent. Core dna's MCP server exposes 80+ tools across 400+ APIs, in production today.
