horizon: AI news and AI regulation tracking for agents
Adds Horizon's free, no-key MCP server — AI news, the daily AI briefing, and an AI regulation tracker for the EU AI Act, US federal & state bills, and UK policy — plus three skills:
| Skill | Ask it |
|---|---|
/ai-news | "What happened in AI today?" · "Anything from Chinese labs this week?" |
/ai-regulation | "Where does the EU AI Act stand?" · "Any new state AI laws?" |
/ai-receipts | "Is that benchmark claim independently verified?" · "How much of the Anthropic coverage is Anthropic talking?" |
The skills exist because the tools return more than headlines: every item carries the shape of its evidence (self-reported vs independently evaluated, legislative stage from the source). The skills tell Claude to relay that rather than flatten it.
Install in Claude Code:
/plugin marketplace add Alchemy-Lab-Infra/horizon-mcp
/plugin install horizon@alchemylab
This folder is also a portable Agent Plugin, for hosts that read that format.

What it runs, sends and stores
The plugin runs nothing on your machine: it is three skills (instructions for Claude) and a pointer to Horizon's remote MCP server at https://horizon.alchemylab.sh/api/mcp. When Claude calls one of its tools, the call goes to that server over HTTPS and carries only the tool's arguments, such as a date, a region, a topic, a search term or a company name, plus the name your app gives itself. It sends no credentials, files or conversation. Horizon keeps a daily count of calls per app name and nothing that identifies you; the details are in the privacy policy at https://horizon.alchemylab.sh/privacy.
