com.getproofsnapPublished by getproofsnap.comOfficial publisherv1.0.1Updated Nov 6, 2026
Capture web pages as signed, timestamped evidence; compare, watch and verify them.
Overview
Hosted MCP server that lets an assistant capture public web pages as signed, timestamped evidence, then verify, compare and monitor them.
- What you can do
- Capture one page or up to 10 pages at once as signed evidence packages
- List, open and verify stored captures, and quote sealed page text with its hash checked
- Compare two captures of the same page and seal the comparison as its own package
- Certify a local file by its SHA-256 without uploading it
- Monitor a page on an interval, a cron schedule or on change
- On Legal plans, create matters, add captures and export a matter as a ZIP with a chain of custody report
- When to use it
- Useful when you need a defensible record of what a public web page said at a given time, for research, compliance, disputes or change tracking, and want the assistant to capture, verify and compare those records directly.
- Requirements
- A remote Streamable HTTP endpoint with OAuth 2.1 sign-in; no local package. A ProofSnap API account with a confirmed email address, separate from the browser extension. New accounts include a sandbox of 50 watermarked test captures. Live captures, schedules, matters and eIDAS timestamps depend on the plan.
Installation
In SourceWeft
- Open ProofSnap in the dashboard and add it to a workspace.
- Connect the required credentials. They are stored privately and never shown on public pages.
- 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/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.Other MCP clients
Add this to your client's mcpServers config. The client completes OAuth sign-in on first connect.

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.
