# Overview

As agents multiply, every enterprise needs an authoritative directory of the tools they can call. What a governed MCP registry must do, what the official registry leaves to you, and the mistakes to avoid.[^s1]

# What it covers

- Why a directory turns into a control plane
- What the official registry gives you, and what it leaves out
- Requirements I would hold a design to
- The agent registry is the other half
- Three mistakes I would avoid

# Bottom line

MCP standardizes the connection. A governed registry decides which connections are allowed. Build the second before you scale the first.
