TypeScript SDK

murphys-laws-sdk on npm is a tiny typed client over the REST API with zero runtime dependencies.

const law = await new MurphysLawsClient().getRandomLaw();

Command-line interface

murphys-laws-cli on npm wraps the API for scripts and terminal use.

npx murphys-laws-cli random
npx murphys-laws-cli search "computer" --limit 3

MCP Server (Model Context Protocol)

An MCP server lets AI agents (Claude Desktop, Cursor, VS Code Copilot) query Murphy's Laws directly.

Quick start, no clone needed:

{
  "mcpServers": {
    "murphys-laws": {
      "command": "npx",
      "args": ["-y", "murphys-laws-mcp"]
    }
  }
}

7 tools: searchlaws, getrandomlaw, getlawoftheday, getlaw, listcategories, getlawsbycategory, submit_law.

See mcp/README.md or npm, or the developer landing page for the full picture.
