Hashproof

Overview

Hashproof is a Model Context Protocol server that enables AI agents to issue verifiable credentials on-chain via x402 for $0.10 per credential. Credentials are stored on Celo and pinned to IPFS, providing a low-cost, decentralized way to generate cryptographic proof of AI-generated claims.

The server runs locally on your machine via the npm package hashproof-mcp, which communicates over stdio with your MCP client. It requires an API key for authentication. The latest release is v0.1.2, with source code available at csacanam/hashproof on GitHub.

Hashproof is listed in the AI & Agents category and works with Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed, and other MCP clients. If you maintain Hashproof, claim this listing to verify ownership and keep information up to date.
