OpenResearch
Zero-auth research MCP: web, academic, finance, news, weather, macro, social, and SEC data — no API keys needed.
OpenResearch provides zero-auth access to a broad range of research and data sources for AI agents, including general web search, academic literature, financial data, news, weather, macroeconomic indicators, social signals, and SEC filings. No API keys are required for core functionality; optional tokens (GitHub, OpenAlex, Stack Exchange) increase rate limits for those specific sources.
