Vtimestamp

MCP server for verifying and querying vtimestamp proofs on the Verus blockchain.

Enables AI agents (Claude Desktop, VS Code, etc.) to verify document timestamps and list all timestamps on a VerusID — directly from the blockchain.

Installation

Claude Code

claude mcp add --transport stdio --scope user vtimestamp-read -- npx vtimestamp-mcp@latest

Claude Desktop

Add to your claude_desktop_config.json:

{
  "mcpServers": {
    "vtimestamp": {
      "command": "npx",
      "args": ["-y", "vtimestamp-mcp@latest"]
    }
  }
}

Using yarn:

{
  "mcpServers": {
    "vtimestamp": {
      "command": "yarn",
      "args": ["dlx", "vtimestamp-mcp"]
    }
  }
}

Using pnpm:

{
  "mcpServers": {
    "vtimestamp": {
      "command": "pnpm",
      "args": ["dlx", "vtimestamp-mcp"]
    }
  }
}

VS Code

Add to your VS Code MCP settings:

{
  "mcp": {
    "servers": {
      "vtimestamp": {
        "command": "npx",
        "args": ["-y", "vtimestamp-mcp@latest"]
      }
    }
  }
}

Tools

vtimestamp_verify

Verify whether a file or text has been timestamped on a VerusID. Provide either a file path or text — the server computes the SHA-256 hash and checks it against the on-chain record.

Parameter	Type	Required	Description
identity	string	Yes	VerusID name (e.g., alice@)
file_path	string	One of	Path to a file to verify
text	string	One of	Text string to verify

Either file_path or text must be provided (mutually exclusive).

Example prompts:

• "Check if the file at /path/to/report.pdf has been timestamped on alice@"
• "Verify this text was timestamped on bob@: I attest that invoice #4521 was approved"

vtimestamp_list

List all timestamps recorded on a VerusID.

Parameter	Type	Required	Description
identity	string	Yes	VerusID name (e.g., alice@)

Example: "What documents has alice@ timestamped?"

vtimestamp_info

Get information about the vtimestamp service.

No parameters.

Example: "What is vtimestamp?"

How It Works

The server queries the public Verus RPC endpoints to read on-chain data. No wallet interaction, no API keys, no authentication required.
