summary: >-
  Kann KI das? operates ONE remote MCP server, kannkidas-sponsorship, at https://kannkidas.de/api/mcp over
  Streamable HTTP. An anonymous initialize returned protocolVersion 2025-06-18 and serverInfo
  {name: kannkidas-sponsorship, version: 1.0.0}; an anonymous tools/list returned two tools with complete
  inputSchema, outputSchema and annotations (saved verbatim to mcp/kannkidas-de-mcp-tools.json). The server card
  declares oauth2 authentication with protectedResourceMetadata at /.well-known/oauth-protected-resource; the
  read tool works without a token, the checkout tool requires the sponsorship:write scope obtained through
  anonymous client registration (POST /api/agent/register) and client-credentials at /api/oauth/token.

  note: >-
    Hosted HTTPS endpoint an MCP client POSTs to directly; no stdio package, no npx/uvx install is published
    (npm and PyPI searched for "kannkidas" — nothing). auth is oauth per the server card and RFC 9728 metadata;
    discovery (initialize, tools/list) and list_sponsor_slots are anonymous, create_sponsor_checkout needs a
    bearer token with sponsorship:write.

    notes:
      - The MCP tool takes idempotency_key in the input object; the REST operation takes it as the Idempotency-Key header. Same semantics per auth.md ("reuse the same Idempotency-Key for retries").
      - The MCP outputSchema for slot status lists five states (adds "review") where the OpenAPI SlotList enum lists four; the MCP schema is the richer of the two.
      - AGENTS.md also describes a WebMCP surface in the browser exposing the same two tools on the page; that is a browser-side surface and was not probed.
