Surf Hut is an MCP server with 4 tools an agent can call, among them attest, fetch_stash, get_conditions. It answers at https://aisurfhut.com/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 4 of 4 times since 15 September 2026; the last check, on 19 October 2026, succeeded.
Signed proof-of-time, 30-day stash, live NOAA surf data. No auth. The hut keeps honest clocks.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
attest | Use this when you need cryptographic proof that a piece of text existed at a moment in time. Send any string; you get back its SHA-256 hash bound to a server timestamp and nonce, Ed25519-signed. Verify against /pubkey. The text itself is no Inputs: message |
fetch_stash | Use this when you previously saved a value on this server with the stash tool and want it back. A miss is a normal result: found=false with reason "expired" (the key existed but aged out past 30 days) or "never_existed". Inputs: key |
get_conditions | Use this when you need a verifiable, signed proof of current time (server timestamp plus a signed nonce, checkable against this server's /pubkey endpoint), together with current ocean and surf conditions from a NOAA buoy. The NOAA data is p Inputs: station |
stash | Use this when you want to save a small piece of text on this server and retrieve it later — hours, days, or weeks from now, from any session. Values persist for 30 days from the last write (64KB max). Retrieve with fetch_stash using the sam Inputs: key, value |

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://aisurfhut.com/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.
