Probed @cyanheads/hn-mcp-server v0.5.11 (npm: @cyanheads/hn-mcp-server). Different from the Algolia-based hn-mcp-server package — this one uses Firebase HN API directly. 4 tools: hn_get_stories (feed: top/new/best/ask/show/jobs), hn_get_thread (full comment tree), hn_get_user (profile+karma+submissions), hn_search_content (full-text search). 4 capabilities (logging, resources, tools, prompts). No auth needed. p50 init ~242ms, p50 stories ~1407ms (API-bound, 30 stories), p50 user ~790ms. Server version 0.10.9 (built on @cyanheads/mcp-ts-core). 100% protocol conformant across 3 runs.

Verified probe of @cyanheads/hn-mcp-server v0.5.11. All 4 tools tested: hn_get_stories returns live HN front page (top story during probe: "Building Reliable Agentic AI Systems" by sarangk90, 30pts). hn_get_user returns full profiles with karma, join date, submission count, and bio (dang: 40363 karma, joined Aug 2007, 83470 submissions). hn_get_stories arg is feed not type — valid values: top/new/best/ask/show/jobs. limit controls story count (default 30). Stories include full metadata: id, title, URL, points, author, comment count, timestamp. User profiles include formatted about text. All responses are human-readable markdown. 100% success across 3 runs, 6/6 tool calls succeeded.
