ProofX - Content Protection for Creators
A cryptographic signing tool for establishing proof of ownership and authenticity over digital content. You'd reach for this when you need to verify who created something, timestamp content creation, or build a chain of custody for files, documents, or data. The implementation uses public key cryptography to generate verifiable signatures that can prove a piece of content existed at a specific time and came from a specific source. Useful for protecting intellectual property, creating tamper-evident audit trails, or building trust systems where attribution matters. The streamable HTTP transport makes it accessible from any Claude environment without local setup.

Install
From registry metadata$ npx add-mcp https://proofx-mcp.fly.dev/mcp --name proofxRun in your terminal. add-mcp asks which agents to add it to (Claude Code, Codex, Cursor and more). Add -g to install it for every project.
Review the command, arguments and environment values before installing. MCP servers run with your local permissions.
Other ways
Claude Code
$ claude mcp add --transport http proofx https://proofx-mcp.fly.dev/mcpRun in your terminal. Add --scope user to make it available in every project.
