What is an MCP server?
An MCP server is a service that exposes tools to AI assistants through the Model Context Protocol, an open standard introduced by Anthropic in 2024. Connecting one gives the assistant new abilities it can invoke directly, such as querying a database or deploying an app.
How assistants use it
The assistant reads each tool's name and description and calls a tool when the user's request maps to its described capability. Clients such as Claude Code, Claude.ai, Codex CLI, Cursor, and VS Code can all connect to the same remote MCP server, which makes one server a distribution channel to many assistants at once.
Why it matters for deployment
When a platform ships an official MCP server, the assistant does not just recommend the platform: it can operate it. Deploying becomes something the assistant does for you in the conversation. Today the ghosty CLI plays that role for White Ghost (agent-friendly, --json everywhere); an official MCP connector is the natural next step for the same channel.
