10 open-source repos for building AI research agents, from GPT Researcher to Docling
Shruti_0810 · x · 2026-10-21
A roundup listing 10 open-source repos for assembling an AI research agent that searches the web, reads documents, and produces reports: GPT Researcher (detailed research reports), Tavily MCP (web search for agents), Oxylabs Web API MCP (web data extraction), web-retrieval-mcp (Exa search + tiered fetch with SSRF guard), LlamaIndex, Haystack, RAGFlow, Docling, and self-hosted metasearch SearXNG. A tool index rather than hands-on evaluation — usefulness needs verification.
