Implement SEP-1649: MCP Server Cards (.well-known Discovery) #1545
Description
This is a tracking issue for implementation of SEP-1649.
Summary
This SEP introduces a standardized mechanism for MCP servers to advertise their capabilities and identity through .well-known URLs following established internet standards for service discovery. The Python SDK needs to implement support for publishing capability documents at standardized .well-known paths describing available tools, resources, and prompts, enable clients to fetch these documents via HTTP without establishing a full MCP session, and provide utilities for both server-side capability document generation and client-side capability document fetching and parsing to enable better server discovery and selection UX.
