Overview

AI-generated overview

A remote MCP server offering Ed25519-signed proof-of-time, a 30-day text stash, and live NOAA buoy surf conditions, with no authentication.

What you can do
Get a signed timestamp with a nonce, plus current ocean and surf conditions from a NOAA buoy, verifiable against the server's public key endpoint. Save a small text value under a key and retrieve it later from any session. Store text for up to 30 days from the last write, 64KB maximum, and get a clear miss result when a key expired or never existed. Request cryptographic proof that a given string existed at a moment in time: a SHA-256 hash bound to a timestamp and nonce, Ed25519-signed, without storing the text itself.
When to use it
Useful when an assistant needs a verifiable timestamp or existence proof for a piece of text, a short-lived cross-session scratchpad, or quick public surf and ocean readings.
Requirements
A remote streamable HTTP endpoint; no authentication, environment variables or headers are declared. Verification of signatures relies on the server's public key endpoint, and surf data comes from a NOAA buoy.
Before you install
Stash contents are stored on a third-party server for up to 30 days, so avoid secrets or sensitive text. Attestation sends the text to the server to be hashed, though the text itself is not stored. Signed timestamps are only as trustworthy as the server's key; verify against the published key.

Installation

In SourceWeft

  1. Open Surf Hut in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/com.aisurfhut%2Fsurf-hut/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Tools

get_conditions

Get signed freshness + surf 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 public and also available directly from ndbc.noaa.gov; the signed freshness bundle is what only this server can give you.

Parametersstation

stash

Stash a value

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 same key.

Parameterskeyrequiredvaluerequired

fetch_stash

Fetch a stashed value

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".

Parameterskeyrequired

attest

Signed proof-of-time for your data

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 not stored.
