About MCP Servers for Web Search & RAG

MCP servers for web search, retrieval-augmented generation, and knowledge base queries. Nerq tracks 7,902 MCP servers in the web search & rag category, each assessed against 52 global AI regulations including the EU AI Act, US state AI laws (California SB53, Colorado SB205), UK AI Bill, and more. Compliance scores are weighted by jurisdiction penalty severity — jurisdictions with higher fines (like the EU AI Act at up to €35M) have more impact on the score than voluntary frameworks.
