ar vs altium-designer-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.; altium-designer-mcp: altium-designer-mcp is an MCP server that provides file I/O and primitive placement tools so AI assistants such as Claude Code, Claude Desktop and VS Code Copilot can create and manage Altium Designer component libraries. The AI handles the decisions, such as IPC-7351B calculations and package layout, while the tool handles file I/O.
