The OpenNews MCP server is a community-maintained MCP server that provides comprehensive financial and cryptocurrency news aggregation with AI analysis. It requires an API token for authentication and communicates with external services via HTTP and WebSocket. Installation involves setting environment variables and configuring the client JSON. Since the server has network permissions and reads local configuration, there is a risk of API key leakage, but a source code review can help verify that the server only connects to expected endpoints. It is suitable for traders, researchers, and AI assistant users interested in real-time market information.
The OpenNews MCP server (developed by 6551Team) aggregates financial and cryptocurrency news from over 85 sources, including major media outlets, exchanges, on-chain data, social media, and market data. All articles are AI-analyzed with an impact score (0-100), trading signal (long/short/neutral), and bilingual summaries (EN/ZH). It provides search, filtering, company information, and real-time WebSocket subscriptions.

Fit and risk
Not for
- Users who require fully local data processing or no API key.
- Users needing historical data or deep archive access.
- Users who need purely offline news aggregation without external dependencies.
Required permissions
- Requires network access to connect to the 6551 API (ai.6551.io) and WebSocket server.
- Requires an API token (OPENNEWS_TOKEN) for authentication.
- Requires filesystem permissions to read the config file (config.json) and run commands in the local project directory.
Risks and side effects
- This server is not an official product; it is third-party (6551Team) and relies on an external API.
- API key could be exposed if misconfigured or leaked in logs.
- News content may be subject to copyright or usage terms; users should ensure compliance.
- External API could be down or change, affecting functionality.
- Server may send push notifications or inaccurate data due to third-party sources.
Troubleshooting
- Ensure OPENNEWS_TOKEN environment variable is correctly set and the token is valid.
- Check network connectivity and firewall blocking ai.6551.io.
- Verify the `/path/to/opennews-mcp` path is correct and the project is properly synced.
- If connection fails, check the API base URL and WebSocket URL configurations.
- Ensure that the MCP client supports stdio transport and the uv command is correctly configured.
- Check server logs for detailed errors.
