About MCP Servers for Web Search & RAG

MCP servers for web search, retrieval-augmented generation, and knowledge base queries.

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.
