opennews-mcp-news-aggregation

Install the OpenNews MCP server with an API token from 6551.io, then call get_latest_news or subscribe_latest_news. The server streams articles from 84+ sources with AI impact scores and trading signals over REST or WebSocket.

Use search_news_by_coin with a coins array such as ["BTC", "ETH"], or combine coins with keywords and engine types via search_news_advanced. Results include tagged coins, AI scores, and signals.

It aggregates 84+ sources in six engine types: news (Bloomberg, Reuters, CoinDesk), listing (Binance, Coinbase, OKX), onchain (Hyperliquid whale trades), meme, market (funding rates, liquidations), and prediction signals.

Yes, an OPENNEWS_TOKEN from https://6551.io/mcp is required. Set it as an environment variable or in config.json; environment variables take precedence over the config file.

Empty results usually mean filters are too restrictive or the coin has no recent news. Increase the limit parameter, verify engine_type and news_type codes with list_news_types, or start with a broad get_latest_news call.

Confirm the token is passed as a URL query parameter and that your network permits WebSocket connections. Implement reconnection with exponential backoff and ensure subscription messages follow JSON-RPC 2.0 format.
