Newsline

Headlines from 17 news outlets across the political spectrum, with left/center/right bias tags and blindspot detection — stories covered by only one side. Free, unauthenticated, no rate limit.

Three ways in: a web reader, a JSON API, and an MCP server.

MCP

claude mcp add --transport http newsline https://news.heyitsmejosh.com/mcp

Stateless streamable HTTP, no auth. Works with any MCP client — Claude Desktop, Claude Code, Cursor.

API

GET https://news.heyitsmejosh.com/api/stories — every parameter is optional.

CORS open to all origins. Feeds are re-pulled at most every 2 minutes; responses themselves are no-store (see below). ts is epoch ms, or 0 when the feed published no date (those sort to the bottom). Full spec: openapi.yaml · orientation for agents: llms.txt.

How it works

One Cloudflare Worker (worker.js) polls 17 RSS feeds and serves the page, the API, and MCP off a single cached pull:

• latest — flat reverse-chronological feed across all sources.

• stories — headlines clustered by title-keyword overlap, each source tagged left/center/right, one-sided clusters flagged blindspot.

Only the feed pull is cached, under a constant key. Filtering happens per-request in shape() downstream of it, and responses go out no-store — the zone's CDN cache ignores query strings, so caching them would serve one caller's ?outlet= to everyone. Nothing is refetched either way; only the cheap filtering runs again.

Clusters are filtered after clustering, and the flat feed before its 120-item cap. Both orderings matter: narrowing the input first would destroy the cross-outlet comparison, and filtering after the cap would hide low-volume outlets.

Bias scores

Each source carries a score from -2 (left) to +2 (right); 0 is center, or non-political for tech outlets like Hacker News and Daring Fireball. These are hand-assigned in FEEDS, not a third-party rating — treat them as a rough lean.

CBC · The Guardian · CNN · NPR · BBC · Global News · National Post · Fox News · NY Post · Daily Wire · Hacker News · Daring Fireball · NBC News · Wall Street Journal · NY Post Opinion · Vancouver Sun · The Province

Add one by appending [outlet, bias, url] to FEEDS at the top of worker.js. Any RSS 2.0 or Atom feed works.

npm test         # node test.mjs — parser, sort, cluster, shape filters
npm run deploy   # wrangler deploy

Cloudflare Workers + Workers Static Assets — one deploy serves the page, /api/stories, and /mcp.
