⚡ What is this?

This is the official Model Context Protocol (MCP) server for the ProofCore Protocol.

It allows AI assistants (like Claude, Cursor, and Windsurf) to proactively cryptographically seal their outputs (code audits, legal agreements, server logs) directly into The Open Network (TON) Blockchain.

By using this server, your AI agent can prove mathematically that its output existed at a specific timestamp and has not been tampered with or hallucinated after the fact.

🛠 Available Tools

1. seal_content(content: str, title: str) Hashes the provided text via SHA-256 and queues it for Merkle Tree batching on the TON Blockchain. Returns an immutable citation badge and an Ed25519 signature.
2. get_proof_status(deal_id: str) Fetches the cryptographic manifest, Merkle path, and TON transaction hash for a previously sealed deal.
3. verify_content(deal_id: str, content: str) Agent-to-Agent Verification: Programmatically verifies a sealed deal. Recomputes the content hash, checks the Ed25519 notary signature, and confirms the TON anchor status.
4. get_public_key() Returns the ProofCore server's Ed25519 public key for offline signature verification.

🚀 Installation & Usage

You do not need an API key to use ProofCore. It operates on a strict Zero-Auth mechanism.

Claude Desktop

Add the following to your claude_desktop_config.json:

{
  "mcpServers": {
    "proofcore": {
      "command": "uvx",
      "args": ["proofcore-mcp"]
    }
  }
}

Cursor IDE

1. Open Cursor Settings -> Features -> MCP
2. Click + Add new MCP Server
3. Select type command
4. Name: proofcore
5. Command: uvx proofcore-mcp

💬 How to use it in chat

Just ask your AI:

• "Audit this Solidity contract and cryptographically seal the final verdict on-chain."
• "Draft an NDA between Alice and Bob, then notarize it via ProofCore."
• "What is the blockchain status of deal UUID?"
• (New) M2M Verification: "Here is a report and a deal ID UUID. Verify its authenticity and signature using ProofCore."

The AI will automatically invoke the tool, anchor/verify the document, and provide you with a verification link!

🔍 Independent & Autonomous Verification (Zero Vendor Lock-in)

ProofCore is built on the philosophy: "Don't trust the notary. Verify the proof yourself."

Every sealed document returns a citation link (e.g., https://proofcore.org/app/<UUID>). Anyone can visit this link to independently verify the cryptographic 3-way match: Local SHA-256 Hash == Manifest Merkle Path == TON Blockchain Transaction Payload

Furthermore, proofs are 100% autonomous. Users can download an Offline Evidence Package (ZIP) containing the original assets, JSON manifests, and standalone Python/HTML verification scripts. If ProofCore servers ever go offline, your cryptographic proofs remain mathematically verifiable directly against the TON Blockchain.

"Don't trust ProofCore. Verify the proof yourself."
