Add Neuronto Agentic Resource Discovery (ARD) Index remote MCP server

[neuronto]

Adds Neuronto Agentic Resource Discovery as a remote MCP server.

What it does. Most discovery servers search one catalog. Neuronto searches its own index and fans out to every other public ARD (Agentic Resource Discovery) registry in the same call, then fuses the rankings, so an agent does not have to pick the right directory first.

Endpoint	https://neuronto.com/mcp
Transport	streamable-http
Auth	None. No API key, no signup, no OAuth
Tools	find_resource, registry_stats (dynamic discovery)
Index	9,871 entries from 5,655 publishers
License	Apache-2.0
Docs	https://neuronto.com/about
Repo	https://github.com/neuronto/neuronto

Also published in the official MCP Registry as io.github.neuronto/agents-tools-search-discovery-ard-registry.

Notes for review

• Remote entry, so no Dockerfile. tools.json is [] per CONTRIBUTING (dynamic tool discovery).
• No secrets or headers block, because the server takes no credentials. Nothing to share on the test-credentials form: the endpoint is callable anonymously as-is.
• Apache-2.0, which the guidelines list as acceptable for consumption.
