Horizon MCP
An MCP server that exposes the Horizon content aggregation and analysis pipeline as a suite of modular tools. It enables users to automate fetching, AI-based scoring, filtering, background enrichment, and summary generation for various data sources.

Horizon MCP
面向 Horizon 的 MCP Server。
服务直接复用 Horizon 原生 Python 实现,按阶段暴露工具,不重复造业务逻辑。
1. 能力概览
工具(Tools)
hz_validate_config:校验 Horizon 配置有效性与关键环境变量是否齐全。hz_fetch_items:抓取并去重新闻内容,写入raw阶段。hz_score_items:调用 AI 对指定阶段内容打分,写入scored阶段。hz_filter_items:按分数阈值过滤并做主题去重,写入filtered阶段。hz_enrich_items:对高分内容执行背景富化,写入enriched阶段。hz_generate_summary:从指定阶段内容生成 Markdown 摘要。hz_run_pipeline:一键执行抓取、打分、过滤、富化、摘要全流程。hz_list_runs:列出最近 run 记录及各阶段产物状态。hz_get_run_meta:读取指定 run 的元数据。hz_get_run_stage:读取指定 run 的阶段内容(raw/scored/filtered/enriched)。hz_get_run_summary:读取指定 run 的摘要内容。hz_get_metrics:读取服务内存指标与调用统计。

2. 前置要求
- Python 3.11+
- 本地可访问 Horizon 仓库(自动发现顺序)
$HORIZON_PATH./Horizon../Horizon/Users/Zhuanz/work-space/Horizon/tmp/Horizon
-
Horizon 配置文件存在:
<horizon_path>/data/config.json -
(可选)MCP 密钥配置文件(避免手动 export):
.cursor/mcp.secrets.json.cursor/mcp.secrets.local.jsonconfig/mcp.secrets.jsonconfig/mcp.secrets.local.json<horizon_path>/data/mcp.secrets.json<horizon_path>/data/mcp-secrets.json
支持字段:
{
"OPENAI_API_KEY": "sk-xxxx",
"GITHUB_TOKEN": "ghp_xxxx"
}
也支持嵌套写法:
{
"env": {
"OPENAI_API_KEY": "sk-xxxx",
"GITHUB_TOKEN": "ghp_xxxx"
}
}
3. 安装与启动
cd /Users/Zhuanz/work-space/Horizon-mcp
python -m venv .venv
source .venv/bin/activate
pip install -e .
# stdio 启动(给 MCP 客户端使用)
horizon-mcp
4. 运行产物
每次 run 会写入:data/mcp-runs/<run_id>/
meta.jsonraw_items.jsonscored_items.jsonfiltered_items.jsonenriched_items.jsonsummary-<lang>.md
5. 设计原则
- 默认无外部副作用:不自动写 Horizon docs、不自动发邮件。
- 阶段可重入:同一
run_id可分步执行。 - 保持主逻辑一致:抓取、评分、富化、总结全部复用 Horizon 原生模块。
6. 客户端接入
接入示例见:docs/integration.md
快速连通检查:
cd /Users/Zhuanz/work-space/Horizon-mcp
make check-mcp
