Overview

AI-generated overview

A remote MCP server that checks C2PA content credentials and returns an official trust snapshot for media provenance triage.

What you can do
It provides C2PA 2.4 triage and a reproducible official trust snapshot, letting an assistant check content-credential evidence for media. The registry description states it handles no media, keys, or payment. No individual tools are listed in the manifest.
When to use it
Useful when an assistant needs to triage whether an image, video, or other asset carries valid C2PA content credentials, or to obtain a reproducible official trust snapshot for provenance checks.
Requirements
A remote streamable HTTP endpoint at No authentication, environment variables, headers, or packages are declared, so no credentials appear to be needed.
Before you install
The description says no media, keys, or payment are involved, so nothing sensitive appears to be requested. No tools are listed, so the exact actions and any data sent to the provider are not documented here.

Installation

In SourceWeft

  1. Open H/M Content Credentials Evidence Verifier 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/net.hogarmas%2Fcontent-credentials/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
