vexis-mcp

Vexis MCP Server — give any MCP-compatible AI agent cryptographic identity and trust infrastructure in minutes. This server wraps the Vexis SDK and exposes its core functions as MCP tools, so agents running in Claude Desktop, Cursor, or any MCP-compatible host can issue passports, verify other agents, record attestations, and query the trust graph.

Quick Setup

Claude Desktop

Add to ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "vexis": {
      "command": "npx",
      "args": ["-y", "vexis-mcp"],
      "env": {
        "VEXIS_API_KEY": "your-api-key-here",
        "VEXIS_BASE_URL": "https://vexis-api.vexis.workers.dev"
      }
    }
  }
}

Cursor

Add to your Cursor MCP config (~/.cursor/mcp.json or workspace .cursor/mcp.json):

{
  "mcpServers": {
    "vexis": {
      "command": "npx",
      "args": ["-y", "vexis-mcp"],
      "env": {
        "VEXIS_API_KEY": "your-api-key-here",
        "VEXIS_BASE_URL": "https://vexis-api.vexis.workers.dev"
      }
    }
  }
}
