Utilito is also available as an MCP server. Connect directly from Claude Desktop, Cursor, or any MCP-compatible client:
{"mcpServers": {"utilito": {"command": "npx", "args": ["-y", "tsx", "https://raw.githubusercontent.com/mattpartida/utilito/main/mcp/index.ts"]}}}The MCP server runs all tool logic locally — no API calls to external servers. Works offline.
