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.\n\n### Related Issues \u0026 PRs\n\n- **Implementation PRs**: n/a\n- **Related PRs**: n/a\n- **Related Issues**: n/a","author":{"url":"https://github.com/felixweinberger","@type":"Person","name":"felixweinberger"},"datePublished":"2025-10-30T11:48:52.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":1},"url":"https://github.com/1545/python-sdk/issues/1545"}
