About Ihor-Sokoliuk/MCP-SearXNG
MCP-SearXNG is an open-source MCP server that connects AI assistants (Claude, Cursor, and any MCP client) to SearXNG instances for private web search. It provides a range of features including web search with filters, failover across multiple instances, URL content reading with Markdown conversion, intelligent caching, SSRF protection, and more. It is self-hosted, privacy-focused, and requires no API keys.
Key Features
Web Search: General, news, and article queries with pagination, time-range/language/safe-search filters, relevance filtering, and formatted-text or raw-JSON output.
Instance Failover Fan-out: Configure interchangeable SearXNG replicas; searches fail over or query all in parallel and merge results.
Direct Answers Metadata: Surfacing SearXNG answers, corrections, suggestions, and infoboxes.
Search Suggestions: Query autocomplete via SearXNG's /autocompleter endpoint.
Instance Capability Discovery: Inspect configured categories, engines, defaults, locales, and plugins.
URL Content Reading: Content-type-aware Markdown conversion with pagination, section filtering, paragraph ranges, and heading extraction.
Intelligent Caching: In-memory cache with configurable TTL and LRU eviction for search results and URL content.
SSRF Protection: Blocks private/internal URLs and redirects by default in all transport modes.
HTTP Transport: Optional Streamable HTTP mode with bearer-token auth, CORS allowlist, and rate limiting.
HTML Fallback: Optionally parse results from HTML page for public instances that reject format=json.
