| Best for | - Developers needing keyless multi-engine search.
- Agent workflows integrated into MCP clients (Claude Desktop, Cursor).
- Service scenarios requiring a local daemon with HTTP API.
| - 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 | - Production-grade search services requiring high reliability and compliance.
- Applications sensitive to search engine terms of service.
- Scenarios requiring guaranteed real-time results, as scraping may be blocked.
| - 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 | - Network access to perform searches and fetch content.
- Local port 3000 when running in HTTP mode (configurable via PORT).
- No API keys or authentication required.
- Optional: Playwright browser automation (requires installing Chromium or connecting to a remote browser).
| - 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 | - Search engines may block frequent requests, causing temporary unavailability.
- Results depend on engine HTML structure, may fail when engines update.
- Some pages may not expose readable content (e.g., JS-heavy landing pages).
- Network compliance when using proxies or fake-IP CIDRs.
| - 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.
