# MCP Server Card

A **Server Card** is a proposed static, discoverable document that describes an MCP server: what it is, who publishes it, and how to reach it, without requiring a client to first open an MCP session. The mechanism is defined in SEP-2127, a Model Context Protocol enhancement proposal opened 21 January 2026 and still being updated as of 3 September 2026, which recommends serving the card at a `/server-card` path relative to the server's own endpoint rather than at a single global well-known location such as `/.well-known/mcp`; an earlier well-known-path proposal (SEP-1649) was superseded. Static cards intentionally omit the live list of tools, prompts and resources, which a client still has to fetch at runtime. Server cards can be advertised to an ARD registry with the media type `application/mcp-server-card+json`. As of the SEP's own text, implementation is limited to experimental SDK work and a demo; mainstream client auto-discovery of server cards is not established. Used by: mcp, ard.
