This is neural search powered by Exa's MCP server, and the big selling point is no API key required. You get three main tools: web search for current news and facts, code search that pulls from GitHub and Stack Overflow, and company research for business intel. There are six more advanced tools available if you tweak the config URL, including deep research and people search. The free tier is legitimately useful for quick lookups. If you're already using mcporter and need search without managing yet another API key, this slots right in. Performance on code search seems solid based on the token range options they expose.
