newsroom-mcp

A private AI news curation MCP server. It ingests AI-related content from RSS/Atom feeds and Hacker News, and exposes MCP tools that let an AI agent cluster that content into curated "stories" and read back a ranked feed — without the server itself making any relevance, clustering, summarization, or ranking decisions. See IDEA.md for the original design spec.

Quick start

npm install
cp .env.example .env   # optional — sensible defaults exist without one
npm run dev             # serves http://localhost:3000/mcp + the Inspector

Two ways to run the server — pick whichever fits your client:

• HTTP (default) — npm run dev / npm run start. Point a client at http://localhost:3000/mcp. Requires the server to stay running.

• stdio — npm run start:stdio (or configure your MCP client to run npx tsx stdio.ts directly). The client spawns the process itself, so nothing needs to be kept running in the background. Both entrypoints share the same tool registrations (src/composition.ts) and the same SQLite database.

Connecting an MCP client

HTTP

Requires npm run dev (or npm run start) already running on port 3000.

claude mcp add (creates/updates .mcp.json):

claude mcp add --transport http newsroom-mcp http://localhost:3000/mcp

Equivalent .mcp.json:

{
  "mcpServers": {
    "newsroom-mcp": {
      "type": "http",
      "url": "http://localhost:3000/mcp"
    }
  }
}

stdio

No server needs to be running — Claude spawns the process itself and kills it when the session ends.

claude mcp add:

claude mcp add newsroom-mcp -- npx tsx /absolute/path/to/newsroom-mcp/stdio.ts

Equivalent .mcp.json:

{
  "mcpServers": {
    "newsroom-mcp": {
      "command": "npx",
      "args": ["tsx", "/absolute/path/to/newsroom-mcp/stdio.ts"]
    }
  }
}

stdio.ts resolves its working directory relative to itself, so the command works from anywhere — but npx tsx still needs to run with this repo's node_modules in scope, hence the absolute path rather than a relative one.

Content sources

• RSS/Atom — curated AI-news feeds (OpenAI, DeepMind, Hugging Face, TechCrunch AI, VentureBeat AI, MIT AI, Anthropic, xAI, and more); see src/config/providers.ts.

• Hacker News — via the Algolia search API, query configurable via NEWSROOM_HN_QUERY.

More on each provider's incremental-fetch strategy in docs/providers.md.

Feed site

The curated feed is also published as a standalone read-only site (GitHub Pages, served from the feed branch), a Vite React app (site/) sharing its story-card UI with the in-app get-feed MCP View via views/_shared/feed/. npm run build:site builds it; .github/workflows/deploy-feed-site.yml deploys it to the feed branch's GitHub Pages root on every main push touching site/**/views/_shared/**. The feed.json data it reads is published separately by npm run publish-feed after a curation run.

Development

npm run lint        # ESLint
npm run test         # Vitest: unit + protocol tests, no network
NEWSROOM_LIVE_TESTS=1 npm run test:live   # opt-in live sanity tests against real APIs
npm run typecheck    # mcp-use typecheck
npm run verify        # lint + test + typecheck
npm run build          # build with mcp-use

Testing strategy explained in docs/testing.md. Architecture and layering in docs/architecture.md. SQLite schema in docs/sqlite-schema.md.

Environment variables

See .env.example for the full list (NEWSROOM_DB_PATH, NEWSROOM_LOG_LEVEL, NEWSROOM_HN_QUERY, NEWSROOM_FETCH_TIMEOUT_MS, NEWSROOM_LIVE_TESTS). None are required — every var has a working default.
