Use cases
- 01Find corroborated events by topic
- 02Monitor breaking news as it develops
- 03Backtest agents against historical events
MCP support
Exposes event and article search, source listings and corpus statistics to MCP clients through Streamable HTTP at `https://newsflash.sh/mcp`.
Configuration
Remote servers need no local install. Pick your client, then copy the config or install in one click.

| category | enum | No | Source categorycrypto | tradfi | business | tech | politics | world | science | health | energy | sports |
| semantic | boolean | No | Rank by meaning (embedding similarity) instead of keyword match — requires q; better for concepts ('monetary easing') than exact strings |
| min_sources | integer | No | Only events corroborated by at least this many distinct outlets — use 2-3 for briefings/headlines to skip single-source noise |

Newsflash
Five years of corroborated news events, queryable by agents. newsflash.sh watches 260+ outlets across geographies and languages and collapses the noise into a deduped event graph — one happening, every source that corroborated it, a confidence score — live to the minute and backfilled five years deep, so agents can backtest on history and act on the wire. Served over MCP, a CLI, a real-time SSE stream, and a plain HTTP API.
Humans read; agents query. No account needed to start.
For agents: Newsflash is a hosted service —
newsflash.shis a domain, not a shell script. There is no local binary or server to install: callhttps://newsflash.sh/api/*(REST) orhttps://newsflash.sh/mcp(MCP) directly. Verify withcurl "https://newsflash.sh/api/events?limit=1".
# keyless test drive — 50 requests/day, straight from your shell
npx newsflash events -q "etf" -c crypto -n 5
npx newsflash stream -c crypto --min-sources 2 # the live wire, corroborated only
curl "https://newsflash.sh/api/events?q=fed&category=tradfi&limit=5"
MCP (primary — for agents)
The event graph is served over MCP's Streamable HTTP transport at
https://newsflash.sh/mcp — listed in the official MCP registry as
sh.newsflash/newsflash, and in Claude's connector directory (in claude.ai
or Claude Desktop: Settings → Connectors → Browse connectors → search
"Newsflash" → Connect). Any other MCP host, point it at the URL:
// Claude Code / Claude Desktop — remote MCP server
{
"mcpServers": {
"newsflash": {
"type": "http",
"url": "https://newsflash.sh/mcp",
"headers": { "Authorization": "Bearer nf_your_key" } // optional — raises limits
}
}
}
Claude Code plugin install:
/plugin marketplace add zatmonkey/newsflash
/plugin install newsflash@newsflash
The endpoint is stateless (each request independent). Tools: get_events,
get_event, search_articles, list_sources, corpus_stats. Setup guides for
Claude, Cursor, ChatGPT and other hosts: newsflash.sh/docs.
OpenClaw
A ready-made skill ships in this repo (skills/newsflash/) —
personalized daily briefings + real-time breaking-news alerts:
clawhub install newsflash # or: openclaw skills install git:zatmonkey/newsflash
Then tell your agent "set up my news briefing". It interviews you for interests, schedules a daily brief, and (if you enable alerts) watches the live stream and pings you when a story crosses your corroboration threshold.
CLI
A standalone, zero-dependency npm package (./cli, published as
newsflash):
npm i -g newsflash
newsflash events -q "etf" -c crypto --from 2026-07-10 -n 5
newsflash events --json -q fed | jq '.[0].sources' # --json for agents
newsflash sources
newsflash stats
newsflash login [email protected] # free API key via emailed one-time code
newsflash me # tier + today's usage
HTTP API
Base URL https://newsflash.sh:
| Method | Route | Purpose |
|---|---|---|
| GET | /api/events?q=&source=&category=&from=&to=&limit= | Deduped events |
| GET | /api/events/:id | One event + corroborating articles |
| GET | /api/articles?… | Raw article search |
| GET | /api/sources | Tracked sources + counts |
| GET | /api/stats · /api/health | Corpus size & freshness |
| GET | /api/stream | Real-time SSE push — event.new / event.corroborated as clustering commits |
| POST | /mcp | MCP server (Streamable HTTP) — the agent-facing surface |
Categories: crypto tradfi business tech politics world science
health energy sports.
OpenAPI
The full REST surface is described in openapi.yaml — an
OpenAPI 3.1 spec with exact request/response schemas for every endpoint above
(including the SSE stream and the auth flow), derived from the live API. Import
it into Pipedream, RapidAPI, Postman, or a custom GPT Action to drive Newsflash
from your own tooling, or generate a typed client with any OpenAPI generator.
Tiers
| Tier | Auth | Limit | How |
|---|---|---|---|
| test | none | 50 req/day (per IP) · 24h lookback · 1 stream | just call the API or MCP endpoint |
| free | API key | 1,000 req/day · 30-day lookback · 2 streams | newsflash login — email + one-time code |
| premium | subscription | 50,000 req/day · full 5-year archive · 10 streams | newsflash upgrade — $29/mo |
Pass the key as Authorization: Bearer nf_… (or x-api-key) — same gate for REST
and /mcp. Every response carries X-RateLimit-Limit / X-RateLimit-Remaining /
X-Newsflash-Tier; limits reset at midnight UTC. Keys are shown once and stored
only as hashes.
How the event graph works
New articles are normalized and matched against recent events using trigram
similarity — across categories, so a crypto outlet and a tradfi outlet
reporting the same happening corroborate one event. Above the similarity
threshold → the article attaches to the event and bumps its corroboration;
otherwise it seeds a new event. confidence = min(1, distinct_sources / 3) — an
event corroborated by 3+ independent outlets maxes out.
That makes the graph a signal instrument: agents can distinguish a
single-outlet rumor (confidence 0.33) from a story the whole press corps is
running (confidence 1.0, sources listed), and query the full archive to
backtest on history.
About this repository
This repo holds the open-source (MIT) client surface of Newsflash: the
zero-dependency CLI (cli/), the Claude Code plugin manifests
(.claude-plugin/), and the MCP registry manifest
(server.json). The Newsflash backend is a hosted service
operated at newsflash.sh and is not part of this
repository.
CLI development: cd cli && npm install && npm run build && node dist/index.js stats.
No runtime dependencies — Node ≥ 20 built-ins only.

New to MCP?
From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
