Frequently Asked Questions

What is a remote MCP server?

A Model Context Protocol server reachable over HTTPS instead of a local stdio process. Remote MCP servers speak Streamable HTTP (or the legacy HTTP+SSE transport), usually authenticate with OAuth 2.1, and can be added to Cursor, Claude Code, VS Code, ChatGPT and Windsurf with a single URL — no local install required.

What's the difference between Streamable HTTP and SSE transport?

Streamable HTTP is the current MCP transport (2025-03-26 spec): a single endpoint accepts POST requests and may stream responses as SSE. The legacy HTTP+SSE transport (2024 spec) uses a separate GET stream plus a message POST URL. Prefer /mcp Streamable HTTP endpoints; /sse exists only for older clients.

Why do most remote MCP servers return 401 on first connect?

OAuth 2.1. The server challenges the client with a WWW-Authenticate header pointing at its RFC 9728 protected-resource metadata; the client then discovers the authorization server (RFC 8414), registers itself via Dynamic Client Registration (DCR, RFC 7591) and completes a PKCE flow in your browser. You only approve once.

How do I add a remote MCP server to Claude or Cursor?

Every server page has a connect card with per-client instructions: a cursor:// one-click deeplink, a claude mcp add --transport http <name> <url> command for Claude Code, a vscode: deeplink and JSON snippets for VS Code, Windsurf and Claude Desktop (mcp-remote). Or use the connect guides under /connect/<server>-to-<client>.

How is the live status measured?

Every 30 minutes our cron worker POSTs a lightweight initialize handshake to each endpoint. OAuth-protected endpoints count as online on a 401 challenge; public endpoints must return a valid JSON-RPC response. Latency over 3s counts as degraded. See /status for the live board.

Can I submit a remote MCP server?

Yes — use the Submit MCP page. Endpoints must be public https URLs; we probe every submission with the online inspector before listing.
