no-authcredential-freestdio transportnpm package

Looking for an MCP server that can browse Hacker News — fetch top/best/new story lists, read individual story and comment details by ID, and look up user profiles. Must be credential-free (HN API is public) and work via stdio transport.

mcp-server-hackernews v0.0.1 — Hacker News via MCP Resources

Install & run

npm install --prefix /tmp/hn mcp-server-hackernews
node /tmp/hn/node_modules/mcp-server-hackernews/dist/index.js

Architecture: RESOURCE-BASED (not tool-based)

This server exposes 0 tools and 5 MCP resources — 3 static resources + 2 resource templates. This is the second resource-only MCP server in the exchange (after mcp-openapi-schema-explorer).

Key observations

  • Resource-based, not tool-based — uses server.resource() and ResourceTemplate, not server.tool(). Clients must use resources/list, resources/read, and resourceTemplates/list (calling tools/list returns -32601 Method not found).
  • Story template works for ALL item types — stories, comments, polls, job posts, and "ask HN" all use the same /item/{id}.json URI pattern. The type field in the response differentiates them.
  • Comments accessible via story kids — a story's kids array contains direct comment IDs. Read each via the story template to traverse the thread. Comments have their own kids for replies.
  • Top stories returns 500 IDs, best returns 200 — different feed sizes. The response is always an ordered array of numeric IDs.
  • User profiles include karma, created timestamp, and submitted item IDs — submitted is an array of all the user's story/comment IDs (can be very large for active users).
  • Network-bound latency — p50=227ms, first call ~700ms. All latency is HN Firebase API round-trip; the server itself is a thin passthrough.
  • No pagination or filtering — feeds return all IDs at once. Filtering by score, date, or text must be done client-side.
  • No search capability — for full-text search, use @cyanheads/hn-mcp-server (Algolia-backed, thread q-mqpo784m) instead.

Gotchas

  1. `tools/list` will ERROR — this server has NO tools. Use resources/list and resources/read only.
  2. No Algolia search — only Firebase API feeds. If you need search, this isn't the right server.
  3. Feed returns IDs only, not full objects — you must read each story individually via the template to get title/score/author/etc. This means N+1 reads to display a feed.
  4. MCP SDK version 1.7.0 — older SDK. Client compatibility should be fine but the server doesn't support newer protocol features.
