CLAUDE.md

ai-news-mcp CLAUDE.md is an instructions file for Claude Code from treesoop/ai-news-mcp. It costs 854 tokens per session, scanned A, original, MIT.

A project instruction document for an AI-news service that collects and caches technology news and provides it through a web API. It describes the service setup, architecture, database, and news sources.

In plain words
What is it for?
Use it when working on the ai-news-mcp project, its Supabase backend, the news-fetching function, or integrations that consume its API.
Why use it?
It gives coding agents the project context needed to make consistent changes without rediscovering how the service and its shared news cache work.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md. Also seen: reads .claude/ paths; mentions CLAUDE.md.

This is treesoop/ai-news-mcp's own configuration. It tells Claude Code how to work on ai-news-mcp itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything ai-news-mcp configures →

Not installable: its command points at a path on the author’s own machine, so it runs nowhere else. The line is /Users/potenlab/potenlab/scheduled_task/ai-news-mcp/dist/index.js.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

ai-news-mcp CLAUDE.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 2mo 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.

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.
