Check by manifest SHA-256, without an account, whether the ProofSnap API issued an evidence package.

Overview

AI-generated overview

A public ProofSnap ledger lookup that tells an assistant whether ProofSnap issued a given evidence package, and when, from its manifest SHA-256.

What you can do
  • Look up an evidence package's manifest SHA-256 in ProofSnap's public ledger
  • Get back whether ProofSnap issued exactly this manifest and when it was issued
  • Check packages issued through the ProofSnap API or dashboard; browser-extension packages are not in this ledger
When to use it
Useful when you have an evidence package or its manifest hash and want an independent, account-free check that ProofSnap issued it and when. It is a verification-only companion to the main ProofSnap capture server.
Requirements
A remote Streamable HTTP endpoint; no account, API key, environment variable or header is needed.
Before you install
It only reports issuance in ProofSnap's ledger, so a package made with the browser extension will not be found there. The lookup sends the manifest hash to ProofSnap's servers.

Installation

In SourceWeft

  1. Open ProofSnap Verify 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.getproofsnap%2Fproofsnap-verify/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

ProofSnap MCP server

Preserve public web pages as signed, timestamped evidence packages from your AI assistant, then verify them, compare versions and monitor pages for changes.

ProofSnap is a hosted remote MCP server. ProofSnap's own servers load the page, not the assistant, and seal a full-page screenshot, the HTML, the page text, metadata and a chain of custody into a signed manifest of SHA-256 hashes with an OpenTimestamps (Bitcoin) proof. On request, an eIDAS qualified timestamp from Disig a.s., a qualified trust service provider on the EU Trusted List, is added.

  • Server URL: https://mcp.getproofsnap.com/mcp (Streamable HTTP)
  • Sign-in: OAuth 2.1 with PKCE, Client ID Metadata Documents and Dynamic Client Registration
  • Documentation and setup for every app: https://getproofsnap.com/api/mcp.html
  • Official MCP Registry: com.getproofsnap/proofsnap

A second public server, com.getproofsnap/proofsnap-verify at https://mcp.getproofsnap.com/verify/mcp, needs no sign-in and checks, by the SHA-256 of its manifest.json, whether ProofSnap's API or dashboard issued an evidence package.

This repository holds the connection files for the directories and apps listed below. The server itself is a hosted service; its code is not part of this repository.

What you can do

  • Capture one page, or up to 10 pages at once, as evidence
  • List, open and verify stored captures
  • Quote the sealed page text, with its hash checked against the signed manifest
  • Compare two captures of the same page and seal the result as its own package
  • Certify a file by its SHA-256 (the file stays on your device)
  • Monitor a page at an interval, on a cron or when it changes
  • On the Legal plans, create matters, add captures and export a matter as one ZIP with a chain of custody report

Example: "Capture https://example.com as evidence."

The connector cannot delete anything, change billing or API keys, or see your password.

What you need

A ProofSnap API account with a confirmed email address, created at https://app.getproofsnap.com/. It is separate from the ProofSnap browser extension. Every new account includes a sandbox of 50 watermarked test captures that are not billed. Live captures count toward your plan; schedules need a paid plan; matters need a Legal plan; an eIDAS timestamp costs $1.99 per stamp. Before a costly request, ProofSnap returns the cost first and runs the request only after you confirm it. Plans: https://getproofsnap.com/api/index.html#pricing

Connect

When you connect, sign in with your ProofSnap account and choose Read only or Read and create.

lookup_manifest

Check whether ProofSnap issued a manifest

Looks up the SHA-256 of an evidence package's manifest.json in ProofSnap's public ledger: whether ProofSnap issued exactly this manifest, and when. It covers packages issued by the ProofSnap API and dashboard; packages made with the browser extension are not in this ledger. Returns issued (true or false) and, when issued, issued_at, the package type and eidas (whether the package carries an eIDAS qualified timestamp). Reads public ledger data only; no account is needed.
