Overview

AI-generated overview

A remote MCP endpoint that returns a signed timestamp receipt for a SHA-256 hash you supply.

What it does
The server issues signed timestamp receipts for a SHA-256 hash. According to its description, you send only the hash and the document itself is never seen by the service. No tool list is published in the manifest, so the exact tool names and parameters are not documented here.
When to use it
Worth considering when an assistant needs a verifiable proof that a given hash existed at a certain time, for example to timestamp a file or record without uploading its contents. It is a narrow, single-purpose service rather than a general utility.
Requirements
A remote MCP client that supports streamable HTTP, connecting to the provider's hosted endpoint. No packages, environment variables, headers, or authentication are declared in the manifest.
Before you install
The manifest declares no authentication, so anyone who can reach the endpoint may be able to request receipts. Only a hash is described as being sent, but a hash of a low-entropy or guessable input can still be matched back to the original. The published description does not state whether receipts are free, retained, or publicly visible.
