mcp-server

@zkdna/mcp-server

MCP server with zkDNA identity-based authentication for AI agent tool calls.

Quick Start

With Claude Desktop

Add to your claude_desktop_config.json:

{
  "mcpServers": {
    "zkdna": {
      "command": "npx",
      "args": ["tsx", "/path/to/zkDNA/packages/mcp-server/src/index.ts"]
    }
  }
}

Standalone

npx tsx packages/mcp-server/src/index.ts

Available Tools

Tool	Required Capability	Description
web_search	search:web	Search the web for information
read_document	read:documents	Read a document by ID
write_report	write:reports	Write a report
agent_info	(none)	View agent identity, capabilities, and audit log

How It Works

1. Server starts with a principal DID (human identity)
2. A default agent is registered with scoped capabilities
3. Each tool call is authenticated (verify agent credential) and authorized (check capability policy)
4. All actions are logged in a verifiable audit trail
5. Unauthorized tool calls are blocked with clear error messages
