Best for
  • Traders and investors who want real-time financial and crypto news at their fingertips.
  • Developers seeking AI-powered market insights with scores and signals.
  • Researchers aggregating news within AI assistant environments like Claude.
  • Developers needing quick, API-key-free web search capabilities
  • Privacy-conscious users who prefer local search execution
  • AI application development with Claude Desktop or Claude Code
  • Privacy-conscious developers who want local data storage.
  • Researchers who need AI-assisted management of large note collections.
  • Users of Markdown editors like Obsidian.
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.
  • Enterprise applications requiring high-scale, reliable search APIs
  • Users needing advanced search features like custom ranking or filters
  • Accessing sites blocked by TLS fingerprinting without installing the optional browser backend
  • Users needing cloud sync and mobile access (unless using the paid cloud service).
  • Minimalists who want zero configuration.
  • Scenarios requiring large-scale vector databases and complex retrieval (local SQLite may be insufficient).
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.
  • Outbound network access to DuckDuckGo and other websites
  • Reads environment variables for SafeSearch, region, and CA certificates
  • Optionally reads a CA certificate file (for TLS-intercepting proxies)
  • Read and write to the local filesystem (default: ~/basic-memory).
  • Perform file and directory operations (create, edit, delete).
  • Access local SQLite database (or Postgres/Milvus if configured).
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.
  • Search endpoints may occasionally return empty results or errors, especially when blocked
  • Content fetching may be subject to SSRF protection, blocking private or loopback addresses by default
  • Misuse could lead to rate limiting or IP blocking
  • Tools have write operations that may unintentionally modify or delete notes.
  • Edit operations may overwrite existing content, though there are protections.
  • Semantic search and reranking features may require model downloads, adding latency.
  • Local data backups are the user's responsibility.
