Relin MCP server

Relin is a remote MCP server that gives an AI agent 52 tools, among them archive_source, cancel_queued_retries, check_portal_host. It answers at https://relin.app/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 22 October 2026, succeeded.

How do I add Relin to Cursor?

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://relin.app/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.

Does Relin need an API key?

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.

Where this comes from

Publisher: io.github.earonesty. Endpoint host: relin.app. ARD identifier: urn:air:io.github.earonesty:mcp:relin. First indexed 10 September 2026. The tools are exactly what the server returned; nothing on this page is inferred from its name. Ranking in Neuronto search is never for sale.
