Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.01125 | $0.01125 |
| Opus 5.5 | $0.00450 | $0.00450 |
| Sonnet 5.5 | $0.00225 | $0.00225 |
| Haiku 4.5 | $0.00112 | $0.00112 |
Grade A, and why
unofficial-HackerNews-MCP-CLI AGENTS.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 103 lines — stays where its author put it; the contents beside it link to each section on GitHub.

What this is
A read-only client for the official HackerNews API. One shared async client backs two entry points:
hn, a Typer CLI (src/hn/cli.py) for the terminal.hn-mcp, a FastMCP 4 server (src/hn/server.py) on MCP SDK v2. It exposes the same operations as MCP tools, read-only resources, and prompts.
The layers, in order:
src/hn/client.pyowns every network call. Keep the CLI and the server thin over it, so the two interfaces never drift. It handles the bounded concurrency, the API'snullsentinel for missing resources, and a short in-process cache (about 60 seconds) for item, user, and story responses.max_itemandupdatesare never cached.src/hn/models.pyholds the Pydantic models.StoryCategoryis the single source of truth for the six story lists (its endpoint stem, display title, and story-list cap). Add a category or a model field here, not in each interface.src/hn/cli.pydoes formatting and wire-up only. Every command takes--format, and--jsonis a shortcut for--format json.src/hn/server.pydoes the same over MCP and also exposeshn://resources and thedaily_digestandthread_summaryprompts.skills/holds the agent-facing skills and is the source of truth:hackernewsfor using the CLI and MCP server, andinstall-hackernewsfor installing them. The copies under.claude/skills/and.agents/skills/are local installs from the skills CLI; edit the source, not the copies. The rootskills-lock.jsonrecords that install, andskills.sh.jsongroups the skills on the skills.sh repo page.
The tools, resources, and CLI are read-only by design. The API has no
authentication and no rate limit. Timestamps are Unix epoch seconds. The
title, text, and about fields contain HTML.

What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
