# pipeworx `hackernews` — Hacker News

## Coverage
Search stories, get top stories, and retrieve items from Hacker News via Algolia and Firebase APIs

Catalog `tool_count`: 5. Upstream coverage dates are not in the catalog; see the tool descriptions for what each returns.

## Access
MCP endpoint `https://gateway.pipeworx.io/hackernews/mcp` — JSON-RPC `tools/list` and `tools/call` over POST, SSE-framed response (`event: message`, one `data:` line; the answer is in `result.structuredContent`). `tools/list` on 2026-10-01 returned 41 tools: these 5 plus the 36 platform tools every pack endpoint lists.

Tools (names and first sentence of each description as served on 2026-10-01):

- `search_hn` — Full-text search Hacker News via Algolia. Required: `query`.
- `get_top_stories` — Fetch the current live top-ranked Hacker News stories from the Firebase API. No required arguments.
- `get_stories` — Fetch Hacker News stories of a given TYPE: top (default), new (newest), best, ask (Ask HN), show (Show HN), or job (jobs/hiring). No required arguments.
- `get_item` — Fetch a Hacker News story or comment by ID (e.g., "42153809"). Required: `id`.
- `get_hn_comments` — Fetch the discussion (top-level comments, actual text) on a Hacker News story by its item ID. Required: `id`.

Client setup: `claude mcp add pipeworx-hackernews -- npx -y mcp-remote https://gateway.pipeworx.io/hackernews/mcp`.

## Auth
Catalog `auth.shape`: `keyless`. Verbatim detail: "No key required — open upstream, callable as-is." No credential is needed at the gateway to list or call (anonymous tier; see the gateway record).

## Rate limits
Gateway anonymous tier: 50 calls per day per IP, reset 00:00 UTC, printed in `x-ratelimit-*` headers (observed 2026-10-01 on the fred and weather packs; this pack was listed, not called). Upstream limits are not stated in the catalog.

## Freshness
Not stated in the catalog. Reliability: measured 100% over 22 synthetic checks in 7d (last checked 2026-10-01).

## Known gaps
- Cost per call as quoted: 50 credits ($0.0050), category `gov`, basis `list`.
- No catalog notes on cost or licence.
- This record is the catalog's description plus one `tools/list`; it is not a test of the upstream data. Reuse it to find the tool, then observe the upstream yourself.
