ar vs Godot-MCP

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.; Godot-MCP: Godot-MCP is a C# editor addon that exposes Godot Editor operations as AI tools and connects them to an MCP server. Any MCP-aware agent can inspect and drive a Godot project.
