Receipts Guard

Receipts Guard extends your AI assistant with the ability to eRC-8004 identity, x402 payments, and arbitration protocol for autonomous agent commerce. The three rails for the machine economy. Rather than leaving your conversation to handle this manually, you can ask your Claude agent directly — and it will take care of the task end-to-end, using Receipts Guard as its underlying capability.

Receipts Guard works across Claude, Cursor, OpenClaw through the Model Context Protocol (MCP) — an open standard that lets AI clients share tools and skills without lock-in. Because MCP is platform-agnostic by design, you install Receipts Guard once and it becomes available across all your AI clients. Whether you're working in Claude for focused sessions or Cursor for integrated workflows, the skill behaves consistently.

Receipts Guard installs like any other MCP skill: drop the folder into `~/.claude/skills/receipts-guard/` for global access, or `.claude/skills/receipts-guard/` to keep it scoped to one project. After a quick restart of Claude, you can trigger it explicitly with `/receipts-guard`, or let the AI decide when it's the right tool for your request.

Receipts Guard has been installed 2,013 times, making it one of the more actively used skills in the AI Agent & Automation category. The install rate suggests it solves a real, recurring need rather than a niche edge case. Like all skills on DiscoverAISkills, it is free to install and use. The broader AI skills ecosystem continues to expand as developers contribute new capabilities across categories like developer tools, data analysis, writing, automation, and more.
