# MCP Server Card

> Category: API, Auth, MCP & Skill Discovery

A Model Context Protocol Server Card tells an agent that you run an MCP server, where it lives and which transport it speaks.

## Why it matters

MCP is how an agent stops scraping your site and starts calling tools you chose to expose.

## Pass criteria

/.well-known/mcp/server-card.json describes the server with a serverInfo.name.

## How to implement it

Goal: Publish an MCP Server Card for agent discovery

/.well-known/mcp/server-card.json describes the server with a serverInfo.name.
