Overview

AI-generated overview

A remote MCP gateway that lets an assistant create blockchain timestamps proving when creative work was made.

What you can do
This remote MCP server exposes a gateway for blockchain timestamping of creative work, so an assistant can register a proof of existence for a piece of content. The registry description frames it as a way to prove you made something first, and it is reachable over streamable HTTP at a hosted endpoint. No individual tools are listed in the manifest, so the exact operations available are not documented here.
When to use it
Consider it when you need a verifiable, time-anchored record of authorship or creation order for creative work, and you want an assistant to submit that record. It is less relevant if you only need local file handling or general productivity tasks.
Requirements
A remote MCP client that supports streamable HTTP, plus network access to the hosted gateway endpoint. The manifest declares no authentication, environment variables, headers, or packages, so no credentials are documented as required.
Before you install
The manifest declares no authentication, which means anyone who can reach the endpoint may be able to submit timestamps; treat that as a risk before relying on it. Timestamping writes a permanent record to a blockchain, so submitted content or its hash may become public and cannot be removed. No tool list is provided, so verify what data is sent and whether any cost applies before use.

Installation

In SourceWeft

  1. Open spArxx.io in the dashboard and add it to a workspace.
  2. Connect the required credentials. They are stored privately and never shown on public pages.
  3. 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/io.sparxx%2Fmcp-gateway/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

Other MCP clients

Add this to your client's mcpServers config. The client completes OAuth sign-in on first connect.

This server asks you to sign in, so SourceWeft could not read its tools without an account and has not indexed them. What a connected account sees can depend on that account and its permissions.
