ResultRail by LarryBuildsAI is a remote MCP server that gives an AI agent 3 tools, among them enrich_domain_result, extract_url_result, quote_data_result. It answers at https://proofbeforepay.vercel.app/resultrail/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 6 of 6 times since 11 September 2026; the last check, on 20 October 2026, succeeded.
Five-to-twelve-cent source-attributed public URL and domain result packs for AI agents.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
enrich_domain_result | Fetch a public domain/homepage and return one source-attributed result pack: company/title/description, industry guess, technographic signals, useful paths, confidence, sources, and receipt hash. Inputs: domain, max_price_usdc, pii_mode, required_fields, url |
extract_url_result | Fetch one public URL and return title, description, headings, text preview, links, confidence, source URL, and receipt hash. Designed for pay-per-success agent extraction. Inputs: max_price_usdc, output, url |
quote_data_result | Free pre-payment quote for one ResultRail public-data result. Returns price, paid endpoint, success contract, and whether the buyer's max price covers the result. Inputs: input, max_price_usdc, task, task_type |

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://proofbeforepay.vercel.app/resultrail/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.
