ar vs mcp-for-beginners

ar: Agent Receipts is an open protocol for generating cryptographically signed audit trails for AI agent actions. It provides SDKs in Go, TypeScript, and Python, plus an MCP proxy that intercepts and signs agent tool calls using Ed25519 signatures. The receipts can be verified independently, enabling accountability and traceability in agentic systems.; mcp-for-beginners: This curriculum introduces the Model Context Protocol (MCP), an elegant solution for AI applications to communicate with various tools and services in a standardized way. It offers hands-on practice in multiple programming languages, guiding beginners from fundamental concepts to building and deploying their own MCP servers and clients.
