Python FastAPI metasearch backend with an MCP server over stdio for Claude Desktop and similar clients. Aggregates results from many providers (Google via direct scraping or SerpBase/Serper keys, DuckDuckGo, Brave, arXiv, PubMed, package registries, and more), normalizes them into a stable JSON schema, deduplicates across engines, and tolerates per-provider failures with timeout isolation and fallback.

Ask Claude to search across multiple engines and return deduplicated results in structured JSON format.
Automate fallback searches when primary search provider fails during agent workflows.
Generate aggregated search results from Google and alternative sources for competitive analysis.
