About Neuronto
Neuronto is an open source search index for the tools AI agents use: more than 122,000 MCP servers, agents and APIs, with the 278,000+ tools those servers actually expose, read by connecting to them. Developers search it on the web; agents query it over REST, MCP or A2A, with no key and no signup. Anyone can submit an endpoint or a domain, and it is indexed after a live check. It implements the open Agentic Resource Discovery (ARD) standard and federates search across the other public ARD registries.
