The Protocol

What is MCP, and why does it matter?

An open standard that lets AI assistants connect to external tools, one protocol, any client.

MCP in plain English

One protocol, any AI client

Instead of writing custom integrations per tool, MCP gives you one server definition that works with every client that speaks the protocol.

SelfHost MCP Server

Your databases, as AI-native tools

@selfhost.dev/mcp-server exposes your SelfHost databases as structured tools — query, inspect, migrate, and monitor, all from the IDE.
