ar vs stackql
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.; stackql: StackQL is an open-source query and provisioning framework that treats cloud and SaaS APIs as SQL-queryable databases. It supports dozens of providers including AWS, GCP, Azure, GitHub, and more, allowing developers and operators to inspect, provision, and manage cloud resources using familiar SQL syntax for both interactive queries and infrastructure automation.
