ResultRail by LarryBuildsAI — questions

Answers built from our own checks of this server.

What can ResultRail by LarryBuildsAI do?

It exposes 3 tools, read directly from the server on our last check. Among them: enrich_domain_result, extract_url_result, quote_data_result. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is ResultRail by LarryBuildsAI working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 73 of 91 checks got a reply (80.2%), average response time 242 ms. The bar chart above shows every period we have measured.

The registry lists ResultRail by LarryBuildsAI as active — why does it not respond?

The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.

How do I connect ResultRail by LarryBuildsAI?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does ResultRail by LarryBuildsAI need an API key?

No. ResultRail by LarryBuildsAI completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 3 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is ResultRail by LarryBuildsAI?

It answers our handshake in 242 ms on average, which is faster than 60% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is ResultRail by LarryBuildsAI open source?

We cannot say either way: 0 stars on GitHub, but we could not determine the licence, and without one the code is not open source by default.
