01 · Install Signet MCP Tools

Claude Code

claude mcp add prismer-ai-signet -- npx -y @signet-auth/mcp-tools

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "prismer-ai-signet": {
      "command": "npx",
      "args": [
        "-y",
        "@signet-auth/mcp-tools"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.
