  mcp_server_card feature flag read from the portal's own SSR payload at
  https://developers.pypestream.com/reference/get_multi-agent
name: Pypestream Documentation MCP Server
status: published
deployment:
  mode: remote
  endpoint: https://developers.pypestream.com/mcp
  auth: unknown
  verified: probed
evidence:
- probe: GET https://developers.pypestream.com/mcp
  status: 200
  body: 'This URL can only be accessed with a MCP client.'
- probe: 'POST https://developers.pypestream.com/mcp {"jsonrpc":"2.0","id":1,"method":"initialize"}'
  status: 401
  body: '{"jsonrpc":"2.0","error":{"code":-32001,"message":"Authorization required"},"id":null}'
- probe: 'POST https://developers.pypestream.com/mcp {"jsonrpc":"2.0","id":1,"method":"tools/list"}'
  status: 401
  note: >-
    No WWW-Authenticate header is returned and no OAuth metadata is served -- both
    /.well-known/oauth-authorization-server and /.well-known/oauth-protected-resource 404 on this
    host -- so an MCP client that follows RFC 9728 cannot discover how to authenticate. The auth
    scheme is therefore recorded as unknown rather than oauth.
tools:
  status: gated
  note: >-
    tools/list is auth-gated, so the live tool schemas were not read and none are asserted here.
    This is the MCP server ReadMe provisions for a documentation portal; its tools operate over
    Pypestream's documentation corpus, not over the six Pypestream API surfaces. No Pypestream API
    operation is known to be exposed as an MCP tool. See mcp/pypestream-tool-crosswalk.yml.
llms_txt_fallback:
  url: https://developers.pypestream.com/llms.txt
  status: 200
  note: >-
    The documentation index the MCP server would serve is available anonymously at llms.txt and is
    saved verbatim to llms/pypestream-llms.txt -- 1 guide and 66 API reference pages. Every
    reference page additionally returns its full OpenAPI fragment when .md is appended to the URL,
    which is how an unauthenticated agent can still read the contracts.
related_surfaces:
  markdown_negotiation: true
  markdown_negotiation_note: >-
    Appending .md to any developers.pypestream.com page returns the markdown source, confirmed on 12
    pages. The portal's SSR payload also declares link_headers true and markdown_negotiation true.
  agent_skills_index: false
  agent_skills_index_note: >-
    The portal declares agent_skills_index true, but /.well-known/agent-skills.json, /skills.txt,
    /.well-known/skills.json, /agents.md and /AGENTS.md all 404.
