🔍 What Is It?

news48 is a self-hosted news pipeline that:

1. Ingests RSS/Atom feeds from sources you choose
2. Downloads full article content (with anti-bot bypass)
3. Parses unstructured HTML into structured data via LLM
4. Fact-checks claims against external evidence
5. Purges stale data on a 48-hour retention window

All of this runs autonomously through four AI agents that schedule themselves via Dramatiq + Periodiq. The agents also learn from mistakes — saving lessons that carry across runs so they get smarter over time.

---

🌐 Web Interface

news48 ships a FastAPI web interface that displays the last 48 hours of verified news. In Docker it's available at http://localhost:8765 (dev) or http://localhost:8000 (prod).

Pages

Route	Description
/	Homepage — top 10 stories, trending topics, expiring articles
/all	All stories with optional tone filter (?sentiment=positive|neutral|negative)
/category/{slug}	Category view with tone filter (e.g. /category/politics?sentiment=negative)
/article/{id}/{slug}	Article detail with fact-check breakdown and related coverage
/cluster/{slug}	Topic cluster — all stories sharing a tag
/sitemap.xml	Auto-generated XML sitemap
/health	Health check endpoint

Features

• AI-rewritten summaries — clear, plain-English summaries for every parsed story
• Fact-check breakdown — per-claim verdicts (verified, disputed, mixed, unverifiable) with evidence
• Tone filter — filter stories by sentiment (positive, neutral, negative) across all pages
• Trending topics — auto-generated topic clusters from article tags
• Expiring stories — catch time-sensitive reporting before it leaves the 48-hour window
• Deduplication — same story from multiple sources is shown once per category
• Category normalization — consistent category names (e.g. artificial-intelligence and artificial intelligence are merged)
• SEO-friendly — canonical URLs, Open Graph tags, JSON-LD structured data, XML sitemap
• Rate limiting — 120 req/min general, 20 req/min for search
• Security headers — X-Content-Type-Options, X-Frame-Options, CSP, Referrer-Policy

🤖 Agents

Four agents run on schedules through Periodiq → Redis → Dramatiq:

Agent	Cron	What it does
Sentinel	*/5 * * * *	Monitors health, creates fix plans, deletes bad feeds
Executor	* * * * *	Claims a plan, runs its steps, verifies outcomes
Parser	* * * * *	Claims articles, runs LLM parsing autonomously
Fact-checker	*/10 * * * *	Verifies claims, searches evidence, records verdicts

🧠 Self-Learning

Agents save lessons when they discover something useful. On the next run, all accumulated lessons are injected into every agent's prompt:

Run 1:  Executor fails with wrong timeout → discovers 600s works → saves lesson
Run 2:  Executor starts with "timeout for fact-check should be 600s" already loaded

Lessons are stored in data/lessons.db (SQLite), cross-pollinated across agents, and human-auditable.

news48 lessons list                              # view all
news48 lessons list --agent executor --json      # filter by agent
news48 lessons add -a executor -c "Timing" -l "Use 600s timeout for fact-checks"

🚀 Quick Start

Prerequisites

• Python 3.12+
• uv package manager
• An OpenAI-compatible LLM endpoint
• A Byparr instance

Install

Option A — Docker (recommended):

One-liner install:

curl -fsSL https://raw.githubusercontent.com/malvavisc0/news48/master/scripts/install.sh | bash

Or clone and run manually:

git clone https://github.com/malvavisc0/news48.git && cd news48
./scripts/install.sh

The interactive installer clones the repository, checks prerequisites, prompts for deployment mode (GPU or external LLM), generates secure passwords, and launches all services.

Option B — Local (uv):

git clone https://github.com/malvavisc0/news48.git && cd news48
uv sync --extra all
cp .env.example .env
# Edit .env with your API keys (see table below)
uv run news48 --help

Extras:

uv sync --extra cli    # CLI + agents only
uv sync --extra web    # Web server only
uv sync --extra all    # Everything

Development

# Start with live reload
docker compose up

# Web UI      → http://localhost:8765
# RedisInsight → http://localhost:8001
# Dozzle       → http://localhost:9999

# Run CLI inside container
docker compose exec dramatiq-worker news48 stats
docker compose exec dramatiq-worker news48 feeds list

# Logs
docker compose logs -f dramatiq-worker
docker compose logs -f web

# Stop
docker compose down        # keep data
docker compose down -v     # fresh start

Production

# Start
docker compose -f docker-compose.yml -f docker-compose.prod.yml up -d

# Web UI → http://localhost:8000

# Backup
docker compose exec mysql mysqldump -unews48 -pnews48 news48 > backup.sql

# Update
docker compose -f docker-compose.yml -f docker-compose.prod.yml build --no-cache
docker compose -f docker-compose.yml -f docker-compose.prod.yml up -d

# Stop
docker compose -f docker-compose.yml -f docker-compose.prod.yml down

Seeding in Docker

The sentinel agent auto-detects an empty database and creates a seed plan — so if seed.txt is in the image, seeding happens automatically.

# Manual seed
docker compose exec dramatiq-worker news48 seed /app/seed.txt

# Verify
docker compose exec dramatiq-worker news48 feeds list

Worker Observability

• RedisInsight → http://localhost:8001 — inspect queues and broker state
• Dozzle → http://localhost:9999 — container log viewer
• CLI → news48 agents status --json — queue depths and cron schedules

🔌 MCP Integration

news48 exposes tools via the Model Context Protocol so AI assistants can interact with your pipeline.

Local Server (stdio)

No auth required — ideal for Claude Desktop, Cursor, etc.

uv run news48 mcp serve

{
  "mcpServers": {
    "news48": {
      "command": "news48",
      "args": ["mcp", "serve"]
    }
  }
}

Tools: fetch_feeds, list_feeds, search_articles, get_article_detail, get_stats, parse_article

Remote Endpoint (HTTP)

The web app exposes an authenticated endpoint at /mcp/. Keys are stored in Redis.

# Create a key
uv run news48 mcp create-key --label "Claude Desktop"
# → Created MCP API key: n48-aBcDeFgHiJkLmNoPqRsTuVwXyZ...
# ⚠️  Copy it now — it can't be retrieved later

# List keys (masked)
uv run news48 mcp list-keys

# Revoke a key
uv run news48 mcp revoke-key n48-...

{
  "mcpServers": {
    "news48-remote": {
      "url": "https://your-domain.com/mcp/",
      "headers": {
        "Authorization": "Bearer n48-your-api-key-here"
      }
    }
  }
}

Tools: browse_articles, get_topic_clusters, article_detail, web_stats

🔒 All keys are prefixed n48- for secret scanner detection. If Redis is unreachable, all MCP requests are denied (fail-closed).
