# MCP Server Card

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

## When to use this skill

Use this when a site fails the "MCP Server Card" check and you need to implement it.

## Goal

Publish an MCP Server Card for agent discovery

## Pass criteria

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

## Implementation

This skill covers the diagnosis. The step-by-step implementation prompt is part
of the paid tier and is served per scan by the API — see https://agent-ready.t0ols.com/llms-full.txt.

## Specifications

- https://modelcontextprotocol.io/
- https://github.com/modelcontextprotocol/modelcontextprotocol

## Verifying

Re-run the scan against the site and confirm the check reports a pass:

    curl -s https://agent-ready.t0ols.com/api/scan \
      -H 'content-type: application/json' \
      -d '{"url":"https://example.com","enabledChecks":["mcpServerCard"]}'
