## AI overview

This primer explains MCP (Model Context Protocol), an open protocol that gives AI models a standard interface for connecting to external tools and data sources. It also outlines current gaps in authentication, discovery, security, sandboxing, secret management, and audit trails.

Navigating Change The way we interact with software is shifting. Instead of clicking through web interfaces and learning different UIs for each system, some people are moving toward natural language as the interface - telling an AI what they want done, and it handles the task completion for them. This shift is happening now, but there's been a missing piece: how does the AI actually connect to and control those systems? MCP Defined MCP (Model Context Protocol) is an open protocol that gives AI models a standardised interface to external tools and data sources. Think of it as a USB-C for AI - before USB-C, every device needed its own connector. MCP does the same for AI-system integration. Instead of building custom integrations for every combination of AI model and external service, you implement MCP once and your AI can talk to everything it needs to. Instead of context-switching between Slack, JIRA, GitHub, and dashboards for example, we'll be able to describe what we need and have an AI assistant handle the interactions. Or as Anthropic defines it: "MCP (Model Context Protocol) is an open-source standard for connecting AI applications to external systems." Current State: A Nascent Protocol Yes, MCP has gaps. Here are a few: It's relatively new (launched November 2024) and the ecosystem is still figuring things out. Authentication and authorisation have a standard but implementation is patchy. Discovery is a work in progress, with a real need for global registry mechanics. Security is largely left to implementers - no built-in sandboxing, no secret management standard, no consistent audit trails. The community is actively working on all of these, and thing are moving very fast. But these are solvable problems and a lot of the changes are happening on the client side so building out servers feels a little more stable. These gaps shouldn't prevent you from getting value today - they just mean you'll need to handle some plumbing yourself and take an abundance of cauti
